Question

Solve each equation.


1. 8/11(n - 10) = 64
2. -0.6(r + 0.2) = 1.8
3. (w - 4/9)(-2/3) = -4/5

Answer 1

Step-by-step explanation:

8/11(n-10)=64

8(n-10) =64 * 11

8n-800= 704

8n = 704+800

8n= 1504

n=1504/8

n=188

-0.6(r+0.2)=1.8

-0.6r-0.12=1.8

-0.6r = 1.8+0.12

-0.6r=1.92

r=1.92/-0.6

r = -3.2

.

(w-4/9)(-2/3)= -4.5

(9w/9-4/9)(-2/3)= -4.5

-18w/27 +8/27=-4.5

-18w +8= 4.5*27

-18w +8= 121.5

-18w = 121.5 -8

-18w = 113.5

w = 113.5/-18

w = -6.305

i hope this is clear to you
