Answer:
Divide the number of minutes by 60.
Step-by-step explanation:
Answer:
29.4
Step-by-step explanation:
if 5 painters takes 21 hours that makes it 4.5 per person so multiply that by 7 and there you go!
It will take her 8 weeks to have enough money for a bike. I made the equation 125+15x=245 and multiplied 15 by 8 to get exactly 245
This is a one-step equation. All you need to do is multiply the 2.5 over to the 20 to get x by itself.
x=50
Hope this helps!
The equation seems to be
1
-------- = 5 ^ (x + 4)
25
In that case, this is the solution, stept by step:
1) factor 25: 25 = 5^2
1
=> ----------- = 5^(x + 4)
5^2
2) invert 5^2
=> 5^(-2) = 5^(x+4)
3) Given that the bases are equal, the exponents also have to be equal:
=> - 2 = x + 4
3) transpose +4:
=> - 2 - 4 = x
=> x = - 6
Answer: - 6
