Answer:

x=41.2

Step-by-step explanation:

First, subtract 7.8 from both sides of the equation, resulting in x-18=23.2

Then, add 18 to both sides of the equation, creating x=41.2

4. The triangles are similar. If QR = 9, QP = 6, and TU = 19, find TS. Round to the nearest tenth.A. 16

B. 28.5

C. 2.8

D. 12.7

Answers

Set up a proportion since the two triangles are proportional.

QP/TS= QR/TU
6/TS= 9/19
cross multiply
(6*19)= (9*TS)
114= 9TS
divide both sides by 9
12.666666= TS
round up to the tenths decimal place
12.7= TS

ANSWER: D) 12.7 is TS

Hope this helps! :)

The correct answer is ;
QR=9
QP=6
TU=19
TS=?
Okay so the triangles are kindred, now the equation can be made
9/16=6/x
So now we are going to cross multiply
9x=114
Now divide both sides by
912 2/3
Your answer is:
TS=12.6 the correct answer is D.12.7

An equation is shown below:5(2x - 8) + 15 = -15

Write the steps you will use to solve the equation and explain each step.

Answers

The first step would be to multiply the parenthesis, ex. 5(2x-8) is 10x-40. Once you simplify the equation, you continue to solve it like a regular equation. The equation should look like: 10x-40+15=-15
Me personally I substitute random numbers till I find the correct number, this takes longer but it works best for my understanding. X= 1. 10(1)-40+15=-15. 10-40 is -30, -30+15=-15. So, x=1

Original Equation.

5(2x - 8) + 15 = -15

First do what is in the parenthesis.

2 x 1 = 2

2 - 8 = -6

5(-6) + 15 = -15

Multiply 5 x -6 to get -30

-30 + 15 = -15

add 15 + -30 to get -15

-15

x = 1

Hope This Helps!
