Shawna, Dexter, and Tilana are solving the equation Negative 2.5 (5 minus n) + 2 = 15.

Shawna says, “I can begin by dividing each side of the equation by –2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.”
Dexter says, “I can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.”
Tilana says, “I can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.”

Kareem's mother's age, in years, is 5 years less than 8 times Kareem's age. If Kareem is k years old, which expression represents his mother's age? 5−8k years 5k−8 years 8−5k years 8k−5 years

Answers

8k-5 years.

k is his age so. 8 times his age would be 8k. 5 years less is 8k-5

Answer:

8k - 5

Step-by-step explanation:

since k represents kareems age, you would have to multiply that by 8. the expression 8•k can be simplified to 8k. the question states that the mothers age is 5 less than 8k, so the correct expression to represent the mothers age is 8k-5

Salama makes fruit baskets with oranges and bananas.
She uses between 8 and 16 oranges and bananas in a ratio of 3 oranges to 2 bananas.

Drag the correct number of fruit into the box to meet these requirements.

Answers

Answer:

9 oranges: bananas

Step-by-step explanation:

ok so I just did somthinglike this with my cuz so here is what I got

Ratio is 3 oranges : 2 bananas, They add up to 5 fruits,  so some possible values are 5, 10, 15 , 20, 25, etc. We need a value between 8 and 16. This means that we need 15/5= 3 portions of fruits and since the ratio is 3:2

We multiply this by the original ratio to get  9 oranges : 6 bananas

A recipe calls for 3/4 cup of sugar for every 3 cups of flour. How much flour should be used for every 1 cup of sugar?
PLEASE HELP ASAP will give brainlyst

Answers

Answer:

4

Step-by-step explanation:

3/4+1/4=4/4=1

3+1=4

1:4

For every 1 cup of sugar, you should use 4 cups of flour in the recipe.

Given that:

Recipe ratio: 3/4 cup of sugar for every 3 cups of flour

To find out how much flour should be used for every 1 cup of sugar,

We can use the concept of ratios.

Step 1: We know that the ratio of sugar to flour is 3/4 to 3.

To make the ratio easier to work with, let's scale it up by multiplying both sides by 4, which gives us 3 cups of sugar to 12 cups of flour.

Step 2: Now, we have the ratio 3 cups of sugar to 12 cups of flour.

To find out how much flour is needed for 1 cup of sugar, we need to divide both sides of the ratio by 3.

After simplifying, we get 1 cup of sugar to 4 cups of flour.

Therefore, for every 1 cup of sugar, you should use 4 cups of flour in the recipe.
