7x - 5y = 21....(4,?)...so sub in 4 for x and solve for y
7(4) - 5y = 21
28 - 5y = 21
-5y = 21 - 28
-5y = - 7
y = 7/5
check..
7(4) - 5(7/5) = 21
28 - 35/5 = 21
28 - 7 = 21
21 = 21 (correct)
the other coordinate is 7/5......(4,7/5)
Answer:
(-26, 32)
Step-by-step explanation:
Not to good with math but the answer may be B
For this case, the first thing to do is to model the rectangular sandbox as a rectangular prism.
The volume of the prism is given by:

Where,
- <em>w: width
</em>
- <em>l: length
</em>
