Answer:
36 years
Step-by-step explanation:
Let
x = Elga's age
Alvin's age = x + 7
Sum of their ages = 79
Sum of their ages = Alvin's age + Elga's age
79 = (x + 7) + x
79 = x + 7 + x
79 = 2x + 7
79 - 7 = 2x
72 = 2x
x = 72/2
x = 36
Elga's age = x = 36 years
Alvin's age = x + 7
= 36 + 7
= 43 years
it's 3/2 because it rises three and goes over two. hope this helps !!
Given:
Number of jelly beens in the car: 785,000
Number of jelly beans in a bag: 800
Number of bags needed to fill the car?
785,000 / 800 = 981.25
Randall claimed = more than 981 bags
Susie claimed = exactly 981 bags.
Randall is correct. More than 981 bags.
981 x 800 = 784,800
There is a missing 200 jelly beans if exactly 981 bags were used. Thus, a quarter of the 982nd bag is used to complete the 785,000 jelly beans.
