Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
Answer:
x=4
Step-by-step explanation:
Answer:
First one.
Step-by-step explanation:
0.3/3=0.1 ==> 0.1$ per meter
0.77/7 ==> 0.11$ per meter
The first option is cheaper, therefore better to buy if you agree with "the cheaper. the better".
if x= 7 what is the value of x-4
7 - 4
=3
if y=3 what is the value of 8y
8 x 3
= 24
if x=7 what is the value of 3x-4
(3 x 7) - 4
= 17
if x=7 and y=3 what is the value of 2x-7y
(2 x 7) -(7 x 3)
= - 7
if x=7 and y=3 what is the value of 4y-X
(4 x 7) - 3
= 25
Hope this helps
I believe it would be 12.16
