Total money earned by Juan = 3w-6

Now Juan saved 1/3 of the money.

So money Juan spent will be 2/3 of what he earned.

Money Juan spent :

$\frac{2}{3} (3w-6)$

Simplifying we get :

2w-4

Emma wrote the expression as 2(3w-6) which is not equal to 2w-4.

So we can say that the expression found by Emma was incorrect .

Evaluate:-|137|+|13|

pychu [463]

Answer:

The answer is 150

Step-by-step explanation:

I think what you mean with the numbers between the "I's" is absolute value. Any number is just that number, so the absolute value of -6, is 6. The absolute value of 24 is 24. That means it's simply 137+13, which is 150.

Combine the following fractions. a. 3/5 + 4/15 b. 5/6 - 1/4

Ne4ueva [31]

Hello there! :)

Answer:

1. $\boxed{\frac{13}{15} }$

2. $\boxed{\frac{7}{12} }$

Step-by-step explanation:

1. 3/5+4/15

First, you multiply by numerator and denominator.

3*3=9

5*3=15

$=\frac{9}{15}$

Then, you had to combine by the fractions.

$\frac{9}{15}+\frac{4}{15}$

Add by the numbers from left to right.

9+4=13

13/15 is the final answer.

______________________________________________

2. 5/6-1/4

First, you multiply by 2 both sides of numerator and denominator.

5*2=10

6*2=12

10/12

3/12

$\frac{10}{12}-\frac{3}{12}$

Subtract by the numerator.

10-3=7

7/12 is the final answer.

Hope this helps!

Thanks!

Have a nice day! :)
