Answer:
9.5,7.5
Step-by-step explanation:
let x and y be the numbers.
let x>y
x=y+2
or x-y=2
(x-y)(x+y)=23
2(x+y)=23
2(y+2+2)=23
2(y+4)=23
2y+8=23
2y=23-8=15
y=15/2=7.5
x=y+2=7.5+2=9.5
Answer:
You know you got one solution if when you solve your equation its not for example 5=5 because that's infinite solutions or 5=6 because that's no solution so one solution would be like y=5
Answer:
I need the following to answer
Step-by-step explanation:
The answers are 2 4 6 and 8
Profit for each bicycle=$180-$70=$110
hence, if you want to find the number of bicycles the store must sell to even out the cost of operating the store, $3300÷$110=30.
Hence you need to sell 30 bicycles.
