Answer:
222 2/9 hours
Step-by-step explanation:
Income = hours * dollars per hours
We need an income of 2000
We get $9/ hour
Substitute in what we know
2000 = hour * $9
Divide by 9 on each side
2000/9 = hours
222.222(repeating) = hours
222 2/9 hours
If we want to know how many days, we will divide by 5 since she works 5 hours a day
222 2/9 ÷5
44 4/9 days
Answer:
5 more weeks
Step-by-step explanation:
5 more weeks if he already sold 15. 10 more weeks if you exclude the 15 he already sold.
If you have questions like this, you have to multiply the number of things that are bought by their prize per things:
so here the number is 10 gallons, and the prize is 3.26 per gallon.
and the answer is 10*3.26, which is 32.6 (multiplying fractions by 10 means "moving" the perdioD by 1 to the right, a tip!)
Answer:
The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.
Answer: 30
Step-by-step explanation:
Example
x=y
x+z=y+z
If we subtract the same number from both sides of an equation, both sides will remain equal.
Example
x=y
x−z=y−z
If we divide both sides of an equation by the same number, both sides will remain equal.
Example
x=y
x÷z=y÷z
If we multiply both sides of an equation by the same number, both sides will remain equal.
x=y
x⋅z=y⋅z
