Step-by-step explanation:
Answer:
soccer balls = 80
basketballs = 120
Step-by-step explanation:
let S = number of soccer balls sold
let B = number of basketballs sold
If the store sold 40 more basketballs than soccer balls, then
B = S + 40
If the store sold $4800 worth of soccer and basketballs last month at a cost of $33 for a soccer ball and $18 for a basketball, then:
33S + 18B = 4800
Substitute the first equation B = S + 40 into the second equation and solve for S:
33S + 18(S + 40) = 4800
33S + 18S + 720 = 4800
51S + 720 = 4800
51S = 4080
S = 80
Substitute S = 80 into B = S + 40 to find B:
B = 80 + 40 = 120
R=rita's age
m=mother's age
g=grandmother's age
mother is 4 times as old as rita
m=4r
grandmother is 2 times as old as mother
g=2m
sum is 104
r+m+g=104
subsitute 4r for m and 2m for g
r+4r+2m=104
subsitute 4r for m
r+4r+2(4r)=104
r+4r+8r=104
13r=104
divide both sides by 13
r=8
4r=m=32
8r=2m=g=64
rita is 8
mother is 32
grandmother is 64
5x-2 is a factor.
The complete factored expression is 3(5x-2)(y-3)
