Charge per hour: $25
Number of hours: h
Total charge: $75
So, to find the number of hours spent on the job, we have to multiply the charge per hour (25) by the number of hours (h); and that expression must be equal to the total charge (75).
Mathematically speaking:
25h=75
Answer:
C.
Step-by-step explanation:
If the radius is 5, that means that from anywhere from the outside edge to the center is 5.
So, if you want to triple the area you have multiply the radius by 3, because a circle is not a oval, meaning that it is still the same all the way around.
U multiply 1 x 17 x 2
The answer is 34 cm3(cubed)
The 3 behind cm is an exponent
Answer:
x = 4
Step-by-step explanation:
- = 6x - - 5
Multiply through by 15 ( the LCM of 5 and 3) to clear the fractions
5(7x + 14) - 3(17 - 3x) = 90x - 5(4x + 2) - 75 ← distribute parenthesis on both sides
35x + 70 - 51 + 9x = 90x - 20x - 10 - 75 , that is
44x + 19 = 70x - 85 ( subtract 44x from both sides )
19 = 26x - 85 ( add 85 to both sides )
104 = 26x ( divide both sides by 26 )
4 = x
