Answer:
sorry for the questions i am not able to give answer
A) Volume = l * w* h --> V = 7 * 5 * 4 --> V = 140 units³
B) 140 units³: Prism B has the same length, width, and height as A, just rotated.
C) As long as the tree numbers' product is 140 units³, it works.
Prism C: 140 * 1 * 1
Prism D: 14 * 2 * 5
Since y is the original cost, let z represent the final cost. So, we set up the expression, (0.12y + y) - 0.03y = z. That shows first the sale, then the tax. From there, we simplify to get 1.12y - 0.03y = z, then simplify it more to get 1.09y = z. We take away the z, and get that the cost, which is 1.09, or 109%, or y (1.09y).
Answer:
B. 1,4
Step-by-step explanation:
1. substitute 4x for y in the second equation since we know y=4x(to find x)
6x-4(4x)=-10
2.solve for x
6x-4(4x)=-10
-4•4x=-16x
6x-16x=-10
6x-16x=-10x
-10x=-10
-10x/-10=-10/-10
x=1
3.substitute 1 for x in either equation(since x=1)to find y
y=4(1)
y=4
x,y=1,4
hope this helps!
