Need answers before 8pm!!
GaryK [48]

We have similar triangles so

12/x = (12+78)/(x+13)

We can skip some algebra by doing the ratio on the pieces.  We'll show it works at the end.

12/x = 78/13

x = 12(13)/78 = 2

We check

12/2 = 6

(12+78)/(2+13) = 90/15 = 6, good

Answer: x=2

Explain your answer !! <br> Have a nice day <br><br> Will give braisnlt
DochEvi [55]

Answer:

(-2,3)

Step-by-step explanation:

Step 1. Isolate x for 3x + 5y = 9

3x + 5y - 5y = 9 - 5y

3x = 9 - 5y

3x/3 = 9/3 - 5y/3

x= (9-5y)/3

Step 2. Simplify

-3*((9-5y)/3) + 3y = 15

-3*((9-5y)/3) = 9 - 5y = -(-5 + 9) + 3y

-9+5y+3y

-9+8y = 15

Step 3 Isolate y for -9+8y=15

-9+8y+9=15+9

8y=24

8y/8 = 24/8

y=3

Step 4 Substitute y = 3

x = (9-5*3)/3

-(6/3) = (-2)

x = -2

What is 15% of $32.50 and please explain how you got your answer please
Ann [662]
You can say : 15% ⇒ ? if 100% ⇒ 32.50 $ 
so next you can say : 15/100 = ?/32.50 ⇒ ? = (15/100) × 32.50 = 15 × 32.50 ÷ 100 = 4.875 ⇒ so the answer is 4.785 $ ;D i hope this will be helpful :))
