The answers are both A) and B).

It is A) because you multiply 5 times 5 which equals 25, and 2 times 5 equals 10.
It’s is B) because you multiply 5 times 2 which equals 10, and 2 times 2 which equals 4.
In conclusion both of these ratios — 25:10 & 10:4 — are proportional, or equal, to 5:2.

I hope this helps!! :)

i need help with a math problem it says solve for t: -3(t - 2) + 7t=9t-9 can you show all the work please​
Virty [35]

Answer:

t = 3

Step-by-step explanation:

Given

- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify

- 3t + 6 + 7t = 9t - 9

4t + 6 = 9t - 9 ( subtract 9t from both sides )

- 5t + 6 = - 9 ( subtract 6 from both sides )

- 5t = - 15 ( divide both sides by - 5 )

t = 3

Ari thinks the perfect milkshake has 3 ounces of caramel for every 5 scoops of ice cream. Freeze Zone makes batches of milkshake
aleksandr82 [10.1K]
<h2>a</h2>

Step-by-step explanation:

Let t be the number of ounces of caramel that has to be added to each scoop of ice cream.

So,for n scoops,there has to be n\times t ounces of caramel.

It is given that for every 5 scoops of ice cream,3 ounces of caramel has to be added.

So,5\times t=3

and t=0.6

For 8 scoops of ice cream,there has to be 8\times t=8\times 0.6=4.8 ounces of caramel added.

But Freeze Zone adds 6 ounces of caramel.

So,Ari thinks that Freeze Zone adds more caramel

The table displays The scores of students on the recent exam. Find the mean of the scores to the nearest 10th.
Dafna1 [17]

Answer:

80

Step-by-step explanation:

To find the mean we add up all the numbers and then divide that number by the amount of numbers we added up.

So in this case we added up 65, 70, 75, 80, 85, 90 & 95. This gives us 560. Now we divide 560 by 7 as that is the amount of numbers we added up. This gives us 80 which means the answer is 80.

I hope this helped! :)
