Answer:
r = -3.2
Step-by-step explanation:
-0.6(r+0.2) = 1.8
Divide by -.6
-0.6/-.6(r+0.2) = 1.8/-.6
r+.2 = -3
Subtract .2 from each side
r+.2-.2 = -3-.2
r = -3.2
Answer:
The number of places correctly identified is 110 places
Step-by-step explanation:
The number of places he correctly identified will be;
11 + 4 + 86 + 9 = 110 places
By using compatible numbers, we refer to the fact that she use an estimate by making sure each of the numbers are closer to the nearest 10th or 5
so 4 will be 5
11 will be 10
86 will be 85
9 will be 10
Adding all of these together, we have
5 + 10 + 85 + 10 = 110
Answer:
$1200
Step-by-step explanation:
First, round the amount paid per month to the nearest hundred.
When rounding, follow this rule: If 5 or more, round up. If 4 or less, round down.
Round 80 to the nearest hundred. Round up because 8 is 5 or more
$80 ⇒ $100
Now calculate amount Joey pays each year.
Since there are 12 months in a year, multiply the rounded payment ($100) per month by 12.
$100 X 12 months = $1200 per year
Therefore, an estimate of how much Joey pays each year for a math tutor is $1200.
