The accompanying diagram shows two triangles. Which proportion could be used to solve for x ?

Answers

Answer:
A) 32/x=12/15

Explanation:
When we compare 32/x, we’re looking the ratio between the two side lengths on the first triangle. When we compare 12/15, we’re looking at the ratio between the two side lengths on the second triangle. These ratios must be equal to each other since the two triangles are similar, and we can use this to solve for x.

Ellie bought snacks for her team's practice. She bought a bag of oranges for $2.66 and a 5-pack of juice bottles. The total cost before tax was $7.46. Write and solve an equation which can be used to determine jj, how much each bottle of juice costs?

Answers

Answer:

(7.46-2.66)/5 do that and you have the answer (I'm lazy)

Step-by-step explanation:

The equation for jj is ($7.46 - $2.66) / 5 and the cost of each bottle of juice is $0.96

The first step to take in order to determine jj, is to determine the total cost of the  5-pack of juice bottles.

Cost of the  5-pack of juice bottles = Total cost before tax - cost of the bag of oranges

Cost of the  5-pack of juice bottles = $7.46 - $2.66 = $4.80

The second step is to determine the cost of each bottle of juice

The cost of each bottle of juice = Cost of the  5-pack of juice bottles / total number of bottles

$4.80 / 5

= $0.96

The previous steps can be summarized into this equation :

The cost of each bottle of juice = (Total cost before tax - cost of the bag of oranges) / total number of bottles

= ($7.46 - $2.66) / 5

= $0.96

Answers

Answer:

Step-by-step explanation:

We know from the equation 43 is 18 less then j. Therefore, if we add 18 to 43, we will get the value of j.

43 + 18 = 61

So first you add 43 and 18 cause the original number is that total - 18 and you get 61

Four friends were born in consecutive years. The sum of their
ages is 94. What is the age of the oldest friend?

Answers

Answer:

25

Step-by-step explanation:

Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.

Now we add the 4 expressions and set the sum equal to 94.

x + x + 1 + x + 2 + x + 3 = 94

4x + 6 = 94

4x = 88

x = 22
