Answer:
1x
Step-by-step explanation:
Sweater = 400
coats = 100
difference= 300
in an equation it would be
4x-x=300
so
3x=300
x=100
sweaters= 4x= 400
coats= x= 100
So, I'm assuming that the x represents multiplication...
Because multiplication has a higher precedence over addition, we'll multiply the numbers first:
18 + 48
Then we simply add:
66
Answer:
Levi is 53 yrs now
Step-by-step explanation:
sum = 76yrs
Levi = 3x -8
Monique = x - 8
8yrs ago
sum= 76 - 8 - 8( the two 8s are from each of the two brothers).
= 60yrs
Levi=3x
Monique=x
3x + x = 60
4x = 60
x = 15yrs
Levi = 3x
= 15 x 3
= 45 yrs(8yrs ago)
now = 45 + 8
= 53yrs now
Monique = x
= 15
now = 15 + 8
23yrs now
