Answer:
r = 9.50x
Step-by-step explanation:
First, we need to find how much money Derrick earns per hour. To do that, we divide how much money he earned by the three hours that he worked:
- = $9.50 earned/hour
So <em><u>every hour, Derrick makes $9.50</u></em>. Now that we know the hourly rate, we can make an equation that will always tell us how much money he makes (r), given the hours (x):
- r = 9.50x (where " <em>x</em> " is the number of hours and " <em>r</em> " is the amount of money he makes)
<u>CHECK:</u>
Let's check our answer. Since we have the equation, let's see if in 3 hours, Derrick actually earned $28.50:
- Equation: <em>r = 9.50x</em>
- x = 3 hours, r should equal $28.50
- r = 9.50(3 hours) = 28.50
- r = $28.50 ✓
The equation works! By substituting the number of hours, we got the right answer.
I’m going to assume the numbers are the other angles so..
Answer: 40 degrees
Why? Every triangles interior angles add up to be 180 so
180-122-18= 40
Answer:
should be 15...
Step-by-step explanation:
Simply divdie
8. 2/5= .4
9. 2/4= .5 TIP( think of quarters, two quarters=.5 or 0 cents)
10.9/10= .9
15/20
Step-by-step explanation:
do 20/100 then would get that answer divide by 100 that would be the expression
