Contact [7]

Answer:

$x=3y+6$

$x+y=110$

The number of CDs sold last week was 84 and the number of CDs sold this week was 26

Step-by-step explanation:

Let

x ---> number of CDs sold last week

y ---> number of CDs sold this week

we know that

Last week she sold 6 more than 3 times the number of CDs that she sold this week

$x=3y+6$ ----> equation A

Ms. Lott’s sold a total of 110 CDs over the 2 weeks

$x+y=110$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$3y+6+y=110$

solve for y

$4y+6=110\\4y=110-6\\4y=104\\y=26$

Find the value of x

$x+26=110\\x=110-26\\x=84$

therefore

The number of CDs sold last week was 84 and the number of CDs sold this week was 26

7 times as much as the sum of 1/3 and 4/5

Aliun [14]

The sum of 1/3 and 4/5 is 17/15 because I turned the fractions into fractions with common denominators.

7 x 17/15 is 119/15 or 7 14/15. You do whole number x numerator and leave the denominator so you get 119/15. The answer is 7 14/15 :)
