2 : 3 (reduced by a factor of 7 from 14 : 21) and 56 : 84 (increased by a factor of 4)

Let's turn that ratio into a fraction: 14/21

14/21... Let's pull some common factors out.

If I remember my times tables, 7 fits into both 14 and 21 so let's divide the top and bottom by 7:
2/3

And 2/3 is the same as 2:3

Answer:

100 Candy Bars

Step-by-step explanation:

Hey!

==================================================================

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?

--------------------------------------------------------------------------------------------------------------

We can create an algebraic Equation to solve this.

<u>- We know that Each Candy Bar costs $1.50.</u>

<u>-We multiply the Amount of Candy Bars with the price. </u>

<u>-We know the profit should be $150</u>

⇒ 1.50x = 150

-<u>Divide</u> by 1.50 on both sides

⇒ 1.50x/1.50 = 150/1.50

-<u>Simplify</u>

⇒ x = 100

==================================================================

A triangle has side lengths of (q+r)(q+r) centimeters, (5q-10s)(5q−10s) centimeters, and (5s-7r)(5s−7r) centimeters. Which expre
Stolb23 [73]

The expression represents the perimeter, in centimeters, of the triangle is 6q - 6r - 5s

<h3>What is the perimeter?</h3>

The formula for perimeter of a triangle is expressed as;

Perimeter = a + b + c

Where a , b and c are the lengths of its side

  • (q+r)
  • (5q-10s)
  • (5s-7r)

Now, let's substitute the values

Perimeter = (q + r) + (5q - 10s) + (5s - 7r)

expand the bracket

Perimeter = q + r + 5q - 10s + 5s - 7r

collect like terms

Perimeter = q + 5q + r - 7r -10s + 5s

Add like terms

Perimeter = 6q - 6r - 5s

Thus, the expression represents the perimeter, in centimeters, of the triangle is 6q - 6r - 5s
