Answer:
3a+5p= 45
Step-by-step explanation:
If a bag of apples costs $3 and a bag of pears costs $5 and you buy 11 bags that costed 45$, then to find out how many bags you bought for each you would need to set up an equation. I go this equation by a being amount of bags of apples and p being amount of bags of pears. since each bag of apples cost $3 and you do not know how many you got you would use 3 times amount of bags of apples (3a) this would be 3a because each bag costs 3 dollars and since you do not know how many bags of pears you bought you would use 5 times the amount of bags of pears (5p) this would be 5p because each bag of pears costs 5 dollars. It equals 45 because you spent $45 total.
Answer:
The numbers are 7 and 42
Step-by-step explanation:
Let x and y be the numbers
x = 6y
x-y = 35
Substitute the first equation into the second equation
6y -y = 35
Combine like terms
5y = 35
Divide by 5
5y/5 = 35/5
y = 7
Now find x
x = 6*y
x = 6*7
x = 42
