3/4x = 9....multiply both sides by 4 <==
3x = 9 * 4
3x = 36
x = 36/3
x = 12
Answer:
3/28
Step-by-step explanation:
James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam.
The total fraction of the book he read in 8 nights = 6/7
Hence,
8 nights = 6/7
1 night = x
Cross Multiply
8x = 6/7 × 1
x = 6/7 ÷ 8
x = 6/7 × 1/8
x = 3/28
Therefore, every night, the fraction of the book he has read is 3/28.

N=43
N-5=38
You add five on both sides, to isolate n.
N=43
Let us assume the number of times Bill saved $75 from his paycheck = x
Let us assume he number of times Bill saved $150 from his paycheck = y
Since he saved 75$ or 150$ for the 8 paychecks.
So, x+y=8
y=8-x (Equation 1)
Since Bill saved $825 from his last 8 paychecks using $75 or $150.
So, 75x+150y=825 (Equation 2)
Substituting the value of 'y' from equation 1 in equation 2,
x = 5
Therefore, Bill saved $75, 5 times from his paycheck.
