15 + 15 + 7.50 equals $37.50
Answer:
L = 3t + 6
108 = L + t
Step-by-step explanation:
first, define the variables:
L = # of CDs sold last week
t = # of CDs sold this week
then, let's write what the words of problem tells us in numbers:
"Last week (L), she sold 6 more (+ 6) than 3 times the number of CDs she sold this week (3t)
L = 3t + 6
"She sold a total of 108 CDs over 2 weeks (L + t)
108 = L + t
Answer:
x = 4
Step-by-step explanation:
6(+4)=48
6+24=48
6+24=48
6+24−24=48−24
6=24
6=24
6/6=24
...
(2x+7)+(3x+58)=90
5x+65=90
5x=25
x=5
