Answer:

x = 12.5 or 25/2

Step-by-step explanation:

Distribute the 4

60 - 4x =10

Subtarct 60 from each side

-4x = -50

divide -50 by -4

x = 12.5 or 25/2

The value of x in the expression is 12.5

An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation.

Given that an expression, (15-x)4=10, we need to find x,

Simplifying, we get

Distributing 4

60 - 4x =10

Subtract 60 from each side

-4x = -50

divide -50 by -4

x = 12.5 or 25/2

Hence, The value of x in the expression is 12.5

Answer:

Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.

So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:

image

You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.

Let’s do some math!

image

So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.

Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.

His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.

8 mins per mile

The runner is talking about part (b)

Part a) is miles per minute and the runner said they did 10 minutes every mile same thing as minutes per mile or part b

Step-by-step explanation:

Since your doing per minute you do you do the amount of miles over the amount of minutes so you can see how many miles the runner went in each minute

And when doing per mile its the same idea you just minutes over miles now so you get for every mile the number of minutes.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Step-by-step explanation:

First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.

Question 17

Using a calculator, you get 6.48074069… for your decimal.

Rounding it to the nearest tenth, your answer would be 6.5

Now, to find the two consecutive whole numbers the square root is between…

However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.

Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!

Question 18

Using a calculator, you get 9.380833151… for your decimal.

This rounds to 9.4

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.

In non-decimal form (simplified radical), your answer can be 2√22.

Question 19

Using a calculator, you get 7.93725393… for your decimal.

This rounds to 7.9

The whole numbers surrounding this decimal are 7 and 8.

You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.

In non-decimal form (simplified radical), your answer can be 3√7.

Question 20

Using a calculator, you get 8.66025403… for your decimal.

This rounds to 8.7

The whole numbers surrounding this decimal are 8 and 9.

You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.

In non-decimal form (simplified radical), your answer can be 5√3.

Question 21

Using a calculator, you get 5.47722557… for your decimal.

This rounds to 5.5

The whole numbers surrounding this decimal are 5 and 6.

You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.

Question 22

Using a calculator, you get 9.84885780… for your decimal.

This rounds to 9.8

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.

Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.

Answer: explanation

Step-by-step explanation:

I am unsure about number 1, but for number 4, you have to fund the unit rate.

Answer:

Answer for Number 1: 54 1/2

Answer for Number 4: $2.36

Step-by-step explanation:

Explanation for number 1:

    1.  length x width = area right? So area divided by length = width!

        159 3/8 divided by 18 3/4 = 8 1/2

    2. width + width + length + length = perimeter right? Now you know the

        width,  you can do...

         8 1/2 + 8 1/2 + 18 3/4 + 18 3/4 = 54 1/2

Explanation for number 4:

    1.  You know that 4 cup = 1 quart right?

        9.44 = 1 quart

    2. So you divide it:

        9.44 / 4 = $2.36

Answer:

Step-by-step explanation:

midpoint of AC=((-3+3)/2,(-5+5)/2)=(0,0)

midpoint of BD=((2-2)/0,(-3+3)/2)=(0,0)

coordinates  of midpoint of AC and BD are same.

∴ AC and BD bisect each other.

\(AC=\sqrt{(3-(-3))^2+(5-(-5))^2 } =\sqrt{6^2+10^2} =\sqrt{136} =2\sqrt{39} \\BD=\sqrt{((-2-2)^2+(3-(-3))^2} =\sqrt{16+36} =\sqrt{52} =2\sqrt{13}\)

Midpoint of AC and BD is ( 0, 0 ), so both bisects each other.

The value of AC = 2 √39 and BD = 2 √13

Here, points given as,

A(–3, –5), B(2, –3), C(3, 5), and D(–2, 3).

We have to find,  AC and BD.

What is distance between two points?

Distance between two points \(P(x_{1} ,y_{1} )\) and \(Q(x_{2} ,y_{2} )\) is given by:

\(d(P, Q) = \sqrt{(x_{2}- x_{1} )^2 +(y_{2}- y_{1} )^2 }\)

Now,

Midpoint of AC = \((\frac{-3+3}{2} ), (\frac{-5+5}{2} ) = ( 0, 0 )\)

Midpoint of BD = \((\frac{-2+2}{2} ), (\frac{-3+3}{2} ) = ( 0, 0 )\)

Hence, Both AC and BD bisects each other.

And, Distance between A and C is,

AC = \(\sqrt{(3 - (-3))^2 +(5 - (-5))^2 } = \sqrt{36 + 100} = \sqrt{136} = 2\sqrt{39}\)

Distance between B and D is,

BD = \(\sqrt{( -2 -2))^2 +(3 - (-3))^2 } = \sqrt{16 + 36} = \sqrt{52} = 2\sqrt{13\)

Answer:

\(x=-6\dfrac{7}{8}\)

Step-by-step explanation:

\(Solve\:9\:\dfrac{1}{4}\:+\:x\:=\:2\:\dfrac{3}{8}\)

Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract

Mixed fraction \(a\dfrac{b}{c}\) can be converted to an improper fraction using

\(a\dfrac{b}{c}=\dfrac{a\cdot \:c+b}{c}\)

\(9\dfrac{1}{4}=\dfrac{9\cdot 4+1}{4} = \dfrac{37}{4}\)

\(2\dfrac{3}{8}=\dfrac{2\cdot 8+3}{8} =\dfrac{19}{8}\)

Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:
\(\dfrac{37}{4}+x=\dfrac{19}{8}\)

Step 3
Solve for x

Answer:

y = 3

Step-by-step explanation:

Since the equation is parallel to the x-axis, it is a horizontal line, which means it has a slope of 0. Since anything times 0 is 0, that means x times 0 is 0, so we can take that out of the equation. That only leaves the y-intercept, which is 3. Substituting it into the equation, we get y = 3.
