3x + 12
The GCF here is 3.
3x / 3 = x
12 / 3 = 4
So we have 3(x + 4)
7y - 7
The GCF here is 7.
7y / 7 = y
-7 / 7 = -1
So we have 7(y - 1)
5x + 30y
The GCF here is 5.
5x / 5 = x
30y / 5 = 6y
So we have 5(x + 6y)
8m + 36n
The GCF here is 4.
8m / 4 = 2m
36n / 4 = 9n
So we have 4(2m + 9n)
Answer:
(1 gallon)/(100 ft^2)
Step-by-step explanation:
(1 gallon)/(100 ft^2) is a good conversion factor. We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:
(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.
Answer : The selling price when you visit the store will be, $435.49
Step-by-step explanation :
Given:
Cost price = $193.55
Profit percent = 125 %
First we have to calculate the total profit.
Total profit = 
Total profit = 
Total profit = $241.94
Now we have to calculate the selling price.
Selling price = Cost price + Total profit
Selling price = $193.55 + $241.94
Selling price = $435.49
Therefore, the selling price when you visit the store will be, $435.49
Let the number of quarter be x and that of nickels be y
total number of coins will be:
x+y=85
thus
x=85-y.........i
total amount of money will be:
0.25x+0.05y=14.25....ii
substituting i in ii we get:
0.25(85-y)+0.05y=14.25
21.25-0.25y+0.05y=14.25
7=0.2y
y=7/0.02
y=35
thus
x=85-35=50
the number of quarters was 50 and that of nickels was 35
