Answer:

32

Step-by-step explanation:

to form a linear pair means when the two angles are added, they equal 180 degrees

3x + 20 + x + 32 = 180

4x + 52 = 180

4x = 128

x = 32

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer

Answers

Answer:

2(3x+7) -15

Step-by-step explanation:

Let x = unknown number

7 is added to 3 times a number

3x+7

Multiply the sum by 2

2(3x+7)

Subtract 15

2(3x+7) -15

Answer:

Let the required number be " x "

Now, 7 is added to 3 times a number : (3x + 7)

Next, the sum is multiplied by 2 : 2(3x + 7)

And then, 15 is substracted from it : 2(3x + 7) - 15

2(3x + 7) - 15 is the final answer.

Step-by-step explanation:

Point V is on the line segment UW. Given VW=5x-4, UV=2x, and UW=5x, determine the numerical length of VW

Answers

So UV+VW=UW
Or 2x+5x-4=5x
So 7x-4=5x
This means that x is generally a low amount as x has to be less than 3 (as 3x7, 21-4=17 and 3x5=15.)
I then tried to input 2 and got 14-4=10 which is correct.
So x=2
We then input x=2 into 5x-4 for the answer.

5(2)-4
10-4

The final answer is 6

Answers

Step-by-step explanation:

• C. P = Cost Price.. , S. P (Sell Price) ,

→ C.P = 100×S.P/100+Profit (when profit)

(a) C.P = 100 × 55/100 + 10 = 5500/110

C.P » $ 50(b) C.P = 100 × 558/100+24 = 55800/124

C.P » $ 450→ C. P = 100 × S.P/100 - loss (when loss)

(c) C. P = 100 × 680 / 100 - 15 = 68000/85

C. P » $ 800

(d) C. P = 100 × 11.78 / 100 - 5 = 1178/95

C. P » $ 12.4

We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.

Answer:

no solution

Step-by-step explanation:

[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2

[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )

[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )

year at a certain high school, there were 60 boys on the honor roll and 130 girls
on the honor roll. This year, the number of boys on the honor roll increased by 5%
and the number of girls on the honor roll increased by 20%. By what percentage did
the total number of students on the honor roll increase? Round your answer to the
nearest tenth (if necessary).

3 ÷ 8

Step-by-step explanation:

1. A fraction has two parts: a numerator and a denominator. The numerator is the dividend (the number that is to be divided by the divisor), and the denominator is the divisor (the number that is divided into the dividend).

2. Given the information above, we know that 3 is the numerator, and 8 is the denominator. This means 3 ÷ 8 = 3/8.
