8x+7 and x-3=10

first add 3 to both side so x is by itself. x=13

Plug 13 to 8x+7

8(13)+7

104+7

=111

3 0

X=13
8*13+7=104+7=111

The equation you need to find x is,

$12x^{\circ}+30^{\circ}=90$ .

Then solving for x gives you $x=5$ .

Hope this helps.

What you need to do is divide 32 by 40 so you end up with 1%. Then you need to multiply that by 25 and you will get 25%

32÷40=0.8

0.8x25=20
