Adam plans to choose a video game from a section of the store where everything is 75%
Minchanka [31]

Answer:

Look below

Step-by-step explanation:

In Adam's expression, d represents the original price of the game. 0.75d represents 75% of the original price; this is the amount of the discount, since everything is 75% off.  Taking the difference of the original price and the discount, d-0.75d, gives us the total price of the game. In Rena's expression, 0.25 represents 25%.  This is because taking 75% off of the price means we still pay 100-75 = 25% of the original price. Multiplying the original price, d, by the 0.25, gives us 25% of the original price; this is the total price.

In a zoo, there are 5 times as many monkeys as there are bears, and the number of bears is 2 fewer than the number of elephants.
HACTEHA [7]

m = 5b

b = e - 2

e = 6


first, solve for the number of bears by replacing e with 6.

b = 6 - 2

b = 4


now do the same for the monkeys.

m = 5b

m = 5(4)

m = 20


check the answer if you wish. the zoo has 20 monkeys.

Use the value of the ratio to determine which ratios are equivalent to 7: 15.
Alexandra [31]

Answer:

a. 21: 45

d. 63: 135

Step-by-step explanation:

Ratio or Relationship of two quantities is the result of comparing two quantities.

Such a comparison could be indicated as a reason, in four different ways, in this way:

1)a: b

2)a ÷ b

3)a/b

d)The reason for a is a b.

Equivalent ratios can be used to show the same relationship between two quantities. Remember that the word "equivalent" means the same.

Problem development

We observe what are the equivalent relationships 7:15 and conclude that they are the following:

a.To find the equivalent ratio, we divide the numerator and denominator by the same number , In this case we divide by 3:

21: 45 = 21/45 = 21÷3 /45÷3 = 7/15

d.To find the equivalent ratio, we divide the numerator and denominator by the same number , In this case we divide by 9:

63: 135= 63/135 = 63÷9 /135÷9= 7/15
