625 sq ft.
100 ft of fence = a square with 25 feet per side
25 x 25 = 625
First, add up all the prices.
3.50 + 1.25 + .76 = 5.51
I tested a few numbers and I discovered that Mike bought 37 pencils.
5.51 * 37 = 203.87
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
Answer: 2/5
Step-by-step explanation: Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
The, multiply the numerators and denominators and get 12/30, then simply by 6 and get 2/5
Key word: sum
twice a number = 2n
Sum of that and 15 = 2n + 15
is = equals
Answer: 2n + 15 = 9
