Answer:
=g-1(4)
Step-by-step explanation:
x=3y+8 ---> y=
y=
9x+15=8x
subtract 15 and 8x from both sides to get
x=-15
Yes because 10 squares is 100 6*20 = 120 which is more than 100
Answer:
$19
Step-by-step explanation:
First you need to make a equation out of given information and this will be easiest to solve as an equation.
3.5 $66.50
1 x
-----------------------
3.5:1=66.50:x
3.5x=66.50/:3.5
x=19
On the right side you put one information(in this case number of yards) and on the left other information(cost) and you make proportion from up to down and solve for x.
