Answer:
10.8
Step-by-step explanation:
The answer is approx. 10.8 per hour.
If you want to round it up, it would be 11. I prefer you not to round though as this is Money. Money should have decimals included.
Divide 432 and 8. You should get 54. Then, divide by 5 and you will get 10.8. Divide by 5 because you still need the rate even though she worked 4 hours one day
1. 4(6+4)
2. 5(1+3)
3. 4(4+5)
4. 4(1+2)
5. 5(2+5)
6. 12(1+3)
7. 24(1+3)
8. 8(5+2)
9. 5(4+10)
10. 4(3+11)
11. 6(6+7)
12. 10(1+6)
Substitute the given number in your formula and solve for the remaining variable.
.. 300 = 100e^(0.7t)
.. 3 = e^(0.7t) . . . . . . . . . divide by 100
.. ln(3) = 0.7t . . . . . . . . . .take the natural logarithm
.. ln(3)/0.7 = t . . . . . . . . . divide by the coefficient of the variable
.. 1.6 = t
Selection B is appropriate.
Answer:
x = 17/3
Step-by-step explanation:
3(2x - 3) + x = 4(x + 2)
7x - 9 = 4x + 8
Add 9 to both sides:
7x - 9 + 9 = 4x + 8 + 9
Simplify:
7x = 4x + 17
Subtract 4x from both sides:
7x - 4x = 4x + 17 - 4x
Simplify:
3x = 17
Divide both sides by 3:
3x/3 = 17/3
x = 17/3
Hope this helps!!
