Answer:
Step-by-step explanation:
5 consecutive multiples of 5....
x , x + 5, x + 10, x + 15, x + 20
the average is 20...
(x + x + 5 x + 10 + x + 15 + x + 20) / 5 = 20
(5x + 50) / 5 = 20
5x + 50 = 20 * 5
5x + 50 = 100
5x = 100 - 50
5x = 50
x = 50/5
x = 10......smallest number
x + 5 = 10 + 5 = 15
x + 10 = 10 + 10 = 20
x + 15 = 10 + 15 = 25
x + 20 = 10 + 20 = 30 <=== largest number

First, we must find the unit price:
20.25/3=6.75
Now we divide:
47.25/6.75=7
I hope you are having a great day, buddy :)
Please mark me as brainliest:)
Answer:
Divide the price by the amount of kgs
Unit price` $ per pound.
1 pound Potato = 2.52/4.5 = 0.56$
1 pound broccoli = 7.75/2.5 = 3.1$
1 pound pear = 2.45/2.5 = 0.98$
If the area is 90 square units. Then the dimension of the rectangle will be 5 units and 18 units.
<h3>What is the area of the rectangle?</h3>
Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W square units
The width of a rectangle is 13 units less than the length.
If the area is 90 square units.
W = L – 13
Then we have
90 = L(L – 13)
L² – 13L – 90 = 0
L² – 18L + 5L – 90 = 0
L(L – 18) + 5(L – 18) = 0
(L – 18)(L + 5) = 0
L = -5, 18
Then the width will be
W = 18 – 13
W = 5 units
Then the dimension of the rectangle will be 5 units and 18 units.
