Answer:
perimeter = 25.13feets
Step-by-step explanation:
width = 25/6 feet
Area = 35 square feet
lenght = Area/width = (35*6)/25 = 8.4feets
perimeter of the rectangle = 2(25/6 + 8.4) = 25.13 feets
X+6=11
X-11=-6
5x=25
2x=10
2x+15=25
Side = 12xy+1
Perimeter = 4(12xy+1)
Perimeter = 48xy + 4 (Answer B)
Answer:
a) 3.375 cents
b) 26 Apples
Step-by-step explanation:
a) Each apple costs .1875 cents, multiply .1875 by 18 to get the cost of 18 apples
b) divide 5 by .1875 to get your 26.6666667 Apples, which would round down because you can't have .6666667 of an apple
We are given that there are a total of 78 students. If we set the following variables:

Then, the sum of all of these must be 78, that is:

Since there are 15 in chemistry and physics and 47 in chemistry, we may replace that into the equation and we get:

Simplifying:

Now we solve for P by subtracting 62 on both sides:

Therefore, there are 16 students in physics
