Answer: x = 10
Step-by-step explanation:
Since B is the midpoint, segment AB and segment BC are equal to each other
3x - 8 = x + 12
Subtract x on both sides.
2x - 8 = 12
Add 8 to both sides
2x = 20
Divide by 2 on both sides
x = 10
That's impossible. Are you factoring?
Answer:
15 minutes
Step-by-step explanation:
The formula is
1/a + 1/b = 1/c to determine joint time where a and b are the times alone and c is the time together
1/10 + 1/ 30 = 1/c
Multiply each side by 30c to clear the fractions
30c( 1/10 + 1/ 30) = 1/c * 30c
3c + c = 30
4c = 30
Divide by 4
4c/4 = 30/4
c = 7.5 minutes
This is the time for 50 pages
We want 100 pages, so multiply by 2
7.5 *2 = 15 minutes
Answer:
10
Step-by-step explanation:
First, you would solve the parentheses, then the brackets then the rest.
So, 40 ÷ [24 - 4 × (2+3)] simplified would be 40÷[24 - 4 × 5]::40÷24-20::40÷4=10
