C=cost per orange ×no. of oranges purchased
Answer:
2640 feet
Step-by-step explanation:
Let's make a proportion using this:
feet/seconds=feet/seconds
We know the car travels 88 feet in 2 seconds.
88/2=feet/seconds
We don't know how many feet the car can travel in 1 minute (which is equal to 60 seconds).So, the car travels x feet in 60 seconds.
88/2=x/60
We want to solve for x. To do this, we have to get x by itself. x is being divided by 60. Multiply both sides by 60, because multiplication is the opposite of division.
60*88/2=x/60*60
The 60s on the right will cancel, so we are left with
60*88/2=x
60*44=x
2640=x
The car can travel 2640 feet in 1 minute.
A=2(l+w)h+l×w
A=2(4+2)×3+4×2
A=36+8
A=44 square feet, so there are 44 square feet of glasses were used to build aquarium. Hope it help!
Answer:
The equation is x= (7.74 /9) 6
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.
Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.
Mathematically speaking:
x= (7.74 /9) 6
Where:
x = Cost of 6 pencils in $
Solving:
x = 0.86 x 6 = $5.16
