Answer:
Simplifying
44 = 2(3x + -5)
Reorder the terms:
44 = 2(-5 + 3x)
44 = (-5 * 2 + 3x * 2)
44 = (-10 + 6x)
Solving
44 = -10 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
44 + -6x = -10 + 6x + -6x
Combine like terms: 6x + -6x = 0
44 + -6x = -10 + 0
44 + -6x = -10
Add '-44' to each side of the equation.
44 + -44 + -6x = -10 + -44
Combine like terms: 44 + -44 = 0
0 + -6x = -10 + -44
-6x = -10 + -44
Combine like terms: -10 + -44 = -54
-6x = -54
Divide each side by '-6'.
x = 9
Simplifying
x = 9

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Your help would be highly appreciated
Answer: We can add the fractions 2/9 and 5/9 together by adding the numerators and keeping the same denominator.
Step-by-step explanation:
if the denominators are different, we can't combine them because the pieces are not the same size. In the first problem, both the denominators are 9 so they have a common denominator. We can add the fractions 2/9 and 5/9 together by adding the numerators and keeping the same denominator.

how to solve 6r - 1 + 6r =11
Answer:
r = 1
Step-by-step explanation:
The equation is,
→ 6r - 1 + 6r = 11
Now the value of r will be,
→ 6r - 1 + 6r = 11
→ 12r = 11 + 1
→ r = 12/12
→ [ r = 1 ]
Hence, the value of r is 1.
Answer:
The answer is 1 r is equal to 1

100 = 100%
60 = 60%

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

Which linear function has the greatest y-intercept? y = 6 x + 1 On a coordinate plane, a line goes through points (0, 2) and (5, 0). On a coordinate plane, a line goes through points (1, 2) and (0, negative 3). y = 3 x + 4.
Answer:
y = 6x + 1 (0,2) (5,0)
Step-by-step explanation:
Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.

Several students measured a 25-mm-long nail and wrote the measurements shown in the table below. Whose measurement had the greatest percent error? Round to the nearest percent.
Please answer the question completely and correctly so I can give you a 5-star rating and thanks.
Answer:
The student whose measurement had the greatest percent error was student 5. Their measurement was 27 mm, and the actual length of the nail was 25 mm. To find the percent error, we use the formula:
percent error = |(measured value - actual value) / actual value| x 100%
Plugging in the values we get:
percent error = |(27 - 25) / 25| x 100% = 8%.
So student 5's measurement had a percent error of 8%.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%

Inequality is a statement of an order relationship between two numbers or algebraic expressions.
The statement that represents the inequality 12x > 10x + 4 is
"The cost of 12 roses is $4 greater than the price of 10 roses".
What is inequality?It is a statement of an order relationship between two numbers or algebraic expressions.
- greater than
- greater than or equal to
- less than
- less than or equal to
We have,
The inequality where a flower shop sells each rose for x dollars is given by:
12x > 10x + 4
We have the following statement provided:
- The cost of 12 roses is $4 greater than the price of 10 roses.
This can be written as:
12x > 10x + 4
- The cost of 12 roses is less than the cost of 10 roses plus a $4 vase.
This can be written as:
12x < 10x + 4y where y = vase
- The cost of 12 roses is greater than the cost of 10 roses plus a $4 vase.
This can be written as:
12x > 10x + 4y where y = vase
- The cost of 12 roses is greater than the cost of 10 roses with a $4-off coupon.
This can be written as:
12x > 10x - 4
We see that
The cost of 12 roses is $4 greater than the price of 10 roses represents the inequality 12x > 10x + 4.
Thus the statement that represents the inequality 12x > 10x + 4 is
"The cost of 12 roses is $4 greater than the price of 10 roses".

The value of (7x²+14x) ÷ (x+2) is
Answer:
7x
Step-by-step explanation:
First, let's factor the expression 7x² + 14x. The greatest common factor of 7x² and 14x is 7x. 7x² / 7x = x, and 14x / 7x = 2, so our factored expression becomes 7x(x + 2).
If we write our expression as a fraction now, we have
\(\dfrac{7x(x+2)}{x+2}\)
And cancelling the x + 2 in the numerator and denominator gives us the value 7x.
