Answer:
76
Step-by-step explanation:
A + B = 127
5.80A + 4.25B = 657.55
Solve with substitution.
5.80A + 4.25(127 − A) = 657.55
5.80A + 539.75 − 4.25A = 657.55
1.55A = 117.80
A = 76
If one cup of sugar needs five cups water than divide the cup of water by five to get 1/5 cups sugar per cup of water :)
The formula is : A=6a^2
So lets say its a cube with edge lengths of 4
We first find out the area of each side by multiplying 4*4
They you multiple the answer of that, 16, by 6, for each of the sides.
A = 96 Units ^2
I think the answer is the 3rd rectangle but I'm not too sure I'm sorry
