Answer:
12
Step-by-step explanation:
5(x-1) +3x = 7(x + 1)
5 × x - 5×1 + 3x = 7 × x + 7 × 1
5x-5+3x=7x+7
8x-5=7x+7
8x-7x=7+5
x=12

Answer:
24 hours
Step-by-step explanation:
Kristen = 8 hours
Kristen and Courtney = 6 hours
Courtney = x hours
in six hours kirsten can do 6/8 of the job
6/8 = 3/4
So kirsten is going to be doing 3/4 of the job
Courtney is only going to do 1/4 of the job
Number of hours it takes Courtney to do the job
6/x = 1/4
Cross product
6 * 4 = x * 1
24 = x
x = 24 hours
It will take Courtney 24 hours to type a 50-page paper on her own
Answer:
B. $2.14
Step-by-step explanation:
Given that
The price of the five supermarkets would be $1.92, $2.01,
$1.89, $2.22, and $2.16
And, each supermarket would be increased by $0.10
So, the today mean price would be
= ($1.92 + $2.01 + $1.89 + $2.22 + $2.16 + $0.10 × 5) ÷ (5)
= $10.7 ÷ 5
= $2.14
Therefore the second option is correct
