# Find 66 2/3 precent of 87. find 1 precent of 3,620 62 1/2 precent of x is 5 what is x. 300 precent of k is 42 what is k

X + 2x + 5 = 62 which can be turned into.
3x + 5 = 62
-5      -5 now we subtract 5 from each side
3x = 57
/3     /3 now we divide 3 from each side to get...
x = 19.
Now to check 19 + (2 x 19) + 5 does in fact equal 62.  Jenny is 19 years old.  Hope this helped.

Jenny´s age is 19 and her mother is 43.

Step-by-step explanation:

1. Plug in the first value of the set

41 is different from 62, so Jenny isn´t 12 years old.

2. Plug in the second value of the set

50 is different from 62, so Jenny isn´t 15 years old.

3. Plug in the third value of the set

59 is different from 62, so Jenny isn´t 18 years old.

4. Plug in the fourth value of the set

Therefore Jenny´s 19 years old.

5. Calculate Jenny´s mother age:

As the sum of their ages is 62 ages, we have the following equation

where

x=Jenny´s age

y=Jenny´s mother age

Therefore Jenny's mother age is 43 years old.

pls mark me brainliest

Jenny´s age is 19 and her mother is 43.

Step-by-step explanation:

1. Plug in the first value of the set:

41 is different from 62, so Jenny isn´t 12 years old.

2. Plug in the second value of the set:

50 is different from 62, so Jenny isn´t 15 years old.

3. Plug in the third value of the set:

59 is different from 62, so Jenny isn´t 18 years old.

4. Plug in the fourth value of the set:

Therefore Jenny´s 19 years old.

5. Calculate Jenny´s mother age:

As the sum of their ages is 62 ages, we have the following equation:

where

x=Jenny´s age

y=Jenny´s mother age

Replacing the Jenny´s age we have:

Solving for y:

Therefore Jenny's mother age is 43 years old.

Jenny is 19 and her mother is 43

Explanation:

Hello!

I'd assume you want Jenny's age and her mother's age.

In that case, we have the following:

x + 2x + 5 = 62

Simplify:

3x + 5 = 62

Simplify:

3x = 57

Simplify:

x = 19

Now, we plug-and-chug:

19 * 2 = 38

38 + 5 = 43

43 + 19 = 62

So we are correct!

Thus, .

Hope this helps!

Step-by-step explanation:

So 66 2/3 percent of 87 is the same as two thirds of 87 so all you do is 87 divided by 3 and then times by 2 to make 58.

1 percent of 3620 is just 3620 divided by 100 as there are a hundred 1 percents in 3620. This makes 3.62

If 5 is 62 1/2 percent of x then you just do 5 divided by 62 1/2 to find one percent then you times that by 100:
5 divided by 62 1/2 =0.08 (1 percent)
0.08 x 100=8 (100 percent) which is the answer

If 300 percent of k is 42 then all we have to do is divided by 3 as we only want 100 percent which is 14 which is the answer!

Good luck!
