4( ) + 12 - 2( ) + ( )
4(4) + 12 - 2(3) + 3
16 + 12 - 6 + 3
28 - 6 + 3
22 + 3
25
Helping in the name of Jesus.
Therefore, 4a + 12 - 2c + c = 25
Step-by-step explanation:a = 4
c = 3
Swap letters for numbers:4a + 12 - 2c + c
(4)(4) + 12 - (2)(3) + 3
16 + 12 - (2)(3) + 3
28 - (2)(3) + 3
28 - 6 + 3
22 + 3 = 25
Draw a conclusion:
Hence your answer is:4a + 12 - 2c + c = 25

Which of the following number lines represents the solution to m/-2 - 7 = -9?
Answers
Answer:
Step-by-step explanation:
the answer is a. (the first one)
Number lines are used to represent relationship between numbers at regular intervals
The number line that represents the equation \(\frac{m}{-2} - 7 = -9\) is number line (c)
The equation is given as:
\(\frac{m}{-2} - 7 = -9\)
Add 7 to both sides of the equation
\(\frac{m}{-2} = -2\)
Multiply both sides of the equations by -2
\(m = 4\)
This means that, the solution to the equation is \(m = 4\)
The number line that represents \(m = 4\) is number line (c)

Find the circumference of the circle. Round your answer to the nearest hundredth. Use 3.14 or 227 for π. the circle is 3
Answers
Answer:
18.84 ft
Step-by-step explanation:
The formula for the circumference of a circle is to multiply the radius (The line that's 3 ft in this case) by 2 and then multiply by π, which the problem says to substitute 3.14 in. Since the radius of this circle is 3, we multiply 2 by 3 and then multiply that by 3.14 to find our circumference. 3 * 2 = 6 and 6 * 3.14 = 18.84. The circumference of this circle is 18.84 ft.
Answer:
18.84 ft

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
b. The resulting product must be greater than 0.
c. The resulting product cannot be less than 10.
Answers
Answer:
a. The resulting product cannot be greater than-10. (False)
b. The resulting product must be greater than 0. (True)
c. The resulting product cannot be less than 10. (True)
Step-by-step explanation:
Explaining Statement (a):
The integer that is given is -10,
Let it will b multiplied with another negative integers let say (-1). Starting with the smallest one in order to clarify all statement.
So, if the resultant product is represented by x, So:
x = (-10)(-1)
Using the sign Multiplication rule which is {(-)*(-)} = +
x = 10
While looking at the result It is greater than -10 because 10 is greater than -10 (So, First Statement is False)\Similarly, the resulting product is greater than 0 because 10 is greater than 0 (So, 2nd statement is true)At the end, the minimum integer choose to multiply with the -10 will be -1. It neither be -0.5 because -0.5 is not an integer. Hence answer will never ever be less than 10. (Last statement is True)Please help and THANK YOU

step 2: find the common denominator between 5 and 4 (20)
step 3: cross multiply them 36/5 x 4 which is going to make the fraction 144/20
step 4: do the same for the other side 21/4 x 5 105/5
step 5: now replace the old fractions with the new ones, 144/20 - 105/20
the answer should be 39/20
simplify to 1 19/20
The solution of the given expression is-
\(7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}\)
We must first transform mixed fractions into improper fractions before we can subtract them.
Let's transform \(7\frac{1}{5}\) it into an improper fraction :
\(7 \frac{1}{5} = \frac{(7 * 5 + 1)}{5} = \frac{36}{5}\)
Let's change \(5\frac{1}{4}\) into an improper fraction now:
\(5\frac{1}{4} = \frac{(5 * 4 + 1)}{4} = \frac{21}{4}\)
We can now subtract the fractions:
To subtract fractions, we need to find a common denominator. The least common multiple or the LCM of 5 and 4 is 20.
Converting the fractions to have a common denominator of 20:
(36/5) * (4/4) = 144/20
(21/4) * (5/5) = 105/20
So the subtraction will be as follows:
\(\frac{36}{5} -\frac{21}{4} =\frac{(36*4)+(21*5)}{4*5} =\frac{144-105}{20}=\frac{39}{20}\)
Therefore, \(7\frac{1}{5} -5\frac{1}{4}\) is equal to \(\frac{39}{20}\) or, \(1\frac{19}{20}\) .
The solution of the given expression is-
\(7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}\)

Answer:
27°
Step-by-step explanation:
XWY and VWY are supplementary
∴ XWY + VWY = 180°
∴ XWY = 180° - VWY
XYW and ZYW are supplementary
∴ XYW + ZYW = 180°
∴ XYW = 180° - ZYW
ΔXWY is a right triangle at X
∴ XWY + XYW = 90°
∴ 180° - VWY + 180° - ZYW = 90°
∴ 180° - 6x + 180° - 4x = 90°
∴ 360° - 10x = 90°
∴ 10x = 270°
∴ x = 27°

Answer: 7221.76 m2
Step-by-step explanation:
Let's first find the area of the rectangle.
The formula is lengthxwidth or LxW
Therefore the area of the rectangle is 85x56= 4760 m2
Now let's find the area of the semicircles. They are two equal semicircles, so we can put it together into one circle.
The formula for the area of a circle is πr2
They gave us the diameter not the radius, so we have to find the radius.
To find the radius, we take the diameter/2 which 56/2 = 28 m
Area= 28x28x3.14= 2461.76
The total area= 2461.76+4760= 7221.76 m2
A number is increased by 20%. Work out the original number of the increase is 600
Answers
Answer:
The answer would be 480
Step-by-step explanation:
The first step is to find out 20% of 600 and that would equal 120, the next step is to subtract 120 from 600 and the answer is 480.
Answer:
480
Step-by-step explanation:
If the number increased by 20% we can decrease it by 20% to get our number before it was increased.
20% of 600 is 120
600-120=480
