13 bikes
You would do 65 divided by 5 because there are 5 times as many new bikes compared to used ones
Brother's weight * 5/8 = 110
Brother's weight * 5/8÷5/8 = 110÷ 5/8
Brother's weight = 176
Answer:


Step-by-step explanation:

Ignore the A before the ±. It wouldn't let me type it correctly.
x² + 2x - 5 = 0
a = 1
b = 2
c = - 5









Two separate equations




Answer:
Theo worked on it for 12 hours. Kade worked on it for 15 hours.
Step-by-step explanation: 12 plus 15 equals 27.
Simplifying
5n + 3 = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n
Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n
Add '-5n' to each side of the equation.
3 + 5n + -5n = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 + 0 = 4 + 5n + -5n
3 = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 = 4 + 0
3 = 4
Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.
