Add 2 to 13 and then divide by 3/8. subtract 16 and then divide by 2. 12 is your answer

3/8 (2x +16) -2 = 13
3/8 (2x) + 2/8 (16) - 2 = 13
6x/8 + 48/8 - 2 = 13
6x/8 + 6 -2 = 13 
6x/8 = 13 -4
6x/8 = 12
6x = 12 x 8
6x = 72
x = 72/6 = 12

I don’t understand helpppppooppoppppp
liraira [26]

Answer:

length is 20 and the width is 5

Step-by-step explanation:

so Area is 100

Area = width * length

legth = 4 * width

This means:

Area = width * 4 width =>  Area = 5 * width

We know that area is 100 so:

100 = 5 * width

that means width = 20, but wait didn't I say that the length is 20? Yes, remember we said length = 4 * width at the beginning, so <u>length = 20</u>.

Now we can easily calculate width as width is 4 times smaller than length, so:

<u>width = 20/4 => 5</u>

We can also test if this is correct by simply using the formula to calculate rectangle. So 5 * 20 = 100, correct!

poizon [28]

The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4

Let 3x and 4x are the seeds from the smaller and bigger pile.

= 4x + 2  (greedy hamster placed another 2 pounds of seeds in the bigger pile)

= 3x - 1/4 (ate 1/4 pound from the smaller pile)

4x + 2 = 5x

Because the quantities of seeds in those piles is in the ratio of 5:16

After solving:

x = 2

Smaller pile weight = 3x = 3(2) = 6

Bigger pile wieght = 4x = 4(2) = 8

Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4
