Part 1 :
if the number of hours (h) is greater than 7.
Equation for the amount(A) in dollar is
Amount (A) = 210 + (h-7)x20
Part 2 :
if she earns 410,
with the same equation
410 = 210 + (h-7)x 20
200 =(h-7)x 20
10 = h-7
17 = h
therefore, number of hours tutored is 17.
Answer:
47 rows
Step-by-step explanation:
To find the amount of needed rows, we will use the math operation division. We will take the total and divide it by the amount in each row.
846/18=47
To seat 18 people in each row, you will need 47 rows.
12 tables seat 4 people = 48 seats
28 tables seat 2 people= 56
therefore there are 104 seats
Answer:
8:16
Step-by-step explanation:
Answer:
n = -6
Step-by-step explanation:
2 ( n + 5 ) = -2
First, solve the brackets.
2n + 10 = -2
Now take 10 to the right side.
2n + 10 -10 = -2 - 10
2n = -12
Then divide both sides by 2.
And now you'll the value of n.
n = ( -6 )
