First we need to know both the formula of A and B.
The formula of A is
C = 5 + 0.25p
with C representing total cost and p representing the amount of checks.
The formula of B is
C = 6 + 0.15p
with C representing total cost and p representing the amount of checks.
To find the point where A and B cost the same, we solve the following equation:
5 + 0.25p = 6 + 0.15p
Collecting terms gives us
-1 = -0.1p
Now we have to divide by -0.1 and we get.
10 = p
p = 10
So our answer: after 10 checks both accounts cost the same amount of money. Answer A.
90% in a fraction is the same as 90/100 simplified, is 9/10.
Hope this helps
Step-by-step explanation:
That's it bro hope it helps you
y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
The volume is the height times the lenght times the width (order does not matter in this case).
4.5 x 3.5 x 7= 110.25
The volume of this block of wood is 110 inches.
