Answer:
.50 cents
Step-by-step explanation:
Yes...thats what u want to do. you want to get the x terms on one side and everything else on the other side.
8x = 7x + 3....so we will subtract 7x from both sides
8x - 7x = 7x - 7x + 3....simplify
1x, or just x = 3 (because ur 7x's cancelled each other out)
so ur answer is : x = 3
and u can check ur answer by subbing it back into the original equation.
8x = 7x + 3
8(3) = 7(3) + 3
24 = 21 + 3
24 = 24 (correct)
Answer:
x=0, y=5
Step-by-step explanation:
Here's the graph below.

Check the picture.
The bases of the 2 prisms are on 2 parallel planes,
a and
b.
Let
c be a third plane, between
a and
b, parallel to both.
Then,
the cross-sections
A and
B , of the 2 prisms, formed by plane c, have
Equal Areas,
this is by
Cavalier's Principle.
