Solve the equation for y in terms of x.
4x + 2y = 8
1 answer:
Answer:
y = 4 , x = 0
Step-by-step explanation:
4x + 2y =8----------equ{1}
make 4x subject of the formula
4x = 8- 2y.................equ(2)
now, substitute 4x into equ{1}
4(8-2y) + 2y = 8
32 - 8y + 2y = 8
Collect like terms
-8y + 2y = 8 - 32
-6y = -24
divide both sides by -6
y = 4
Substitute y into equ(2)
4x = 8-2(4)
4x = 8 - 8
4x = 0
divide both sides by 4
x = o
CHECK
4(0) + 2(4) =8
0 + 8 = 8

Answer:
84 cubic feet
Step-by-step explanation:
First, multiply the numbers to get the volume.
5 2/5 * 4 2/3= 25 1/5
25 1/5 * 4 4/9= 112
Then, we can find 3/4 of that.
112*3/4=84.
