Answer:
Step-by-step explanation:
Start with the given inequality and solve it for x.
First, add 4 to both sides: 5x > 25
Next, divide both sides by 5: x > 5
The solution (set) is x > 5.
Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
A will be the right answer
I believe the mean its 14!
A) x= 5
b) x= 1
basically, 5x5x5=125 so that mean 5 to the power of 3 equals 125. This says x-2, so 5-2=3 which completes the equation of 5 to the power of 3. same with the second one.
