7 Hours. 315 divided by 45 equals 7.
Hello!
You can make two expressions based on what you know
let x equal the larger number
let y equal the smaller number
x + y = 95
x + 2y = 120
We can use elimination to get rid of x
You can subtract the two equation to get rid of x
-y = -25
Since y is negative we can multiply both sides by -1 to make y positive
y = 25
Now we can put this into one of the other equations to find x
x + 25 = 95
subtract 95 from both sides
x = 70
The answers are 70 and 25
Hope this helps!
Answer:2m^2+mn+2m+9n-3
Step-by-step explanation:
m(2+n-m)+3(3n+m^2-1)
open brackets
2m+mn-m^2+9n+3m^2-3
Collect like terms
3m^2-m^2+mn+2m+9n-3
2m^2+mn+2m+9n-3
