Answer:

y/2

Step-by-step explanation:

x+3=y+2

------  --------

3          2

Using cross products

2(x+3) = 3(y+2)

Distribute

2x+6 = 3y+6

Subtract 6 from each side

2x+6-6 = 3y+6-6

2x= 3y

Divide each side by 2

2x/2 = 3y/2

x = 3/2 y

We want to find x/3

Divide each side by 3

x/3 = 3/2 y * 1/3

x/3 = 1/2 y

Plsss help me !!!!!!!!!!!!!!!
elena-s [515]

Answer:

5.283

Step-by-step explanation:

[1] First, a quotient is the result of a divison problem, so you are looking for a simplifed version of the answer

[2] \sqrt{7} is roughly 2.65, although I am not sure how far out they want you to go

[3] We now have \frac{14}{2.65} which is rounded about to 5.283!

(I hope that this helps and is correct, have a nice day!)

Ari is recording the number of laps he walks around the track each day, On Day 1, he walks 8 laps. On Day 2, his number of laps
alina1380 [7]

Step-by-step explanation:

to compare day 1 with day 2 :

100% = 8

1% = 100%/100

25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2

so, on day 2 he walks 8+2 = 10 laps.

on day 3 he walks then 10-1 = 9 laps.

so, now, to calculate the % decrease compared to day 2

100% = 10

1% = 100%/100 = 0.1

how many % is represented by this 1 lap he was walking less ?

1 / 1% = 1 / 0.1 = 10%

so he had a 10% decrease from day 2 to day 3.

You choose 3 vowels out of the 7 tiles shown. How many vowels would expect to get out of 105 tiles?
malfutka [58]

Answer:

45

Step-by-step explanation:

If you treat this as a ratio, it would be 3 vowels to every 7 tiles. If one value in the ratio is multiplied by a number, the other should be multiplied by the same number. So if there are 105 tiles, the 7 in the ratio was multiplied by 15. Multiply the other value, 3, by the same number and you get 45.
