When 2(3/5x+2 3/4y-1/4x-1 1/2y+3) is simplified, what is the resulting expression?

erik [133]

Answer:

Option B is correct.

Step-by-step explanation:

$2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)$

We need to solve the above expression.

First Convert Mix fraction into improper fraction

$2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)\\=2(\frac{3}{5}x+ \frac{11}{4}y-\frac{1}{4}x-\frac{3}{2}y+3)$

Combining the like terms

$=2(\frac{3}{5}x-\frac{1}{4}x+ \frac{11}{4}y-\frac{3}{2}y+3)$

Solving like terms

$=2(\frac{3x*4-5x}{20}+ \frac{11y-3y*2}{4}+3)\\=2(\frac{12x-5x}{20}+ \frac{11y-6y}{4}+3)\\=2(\frac{7x}{20}+ \frac{5y}{4}+3)$

Multiply each term with 2

$=2*\frac{7x}{20}+ 2*\frac{5y}{4}+2*3\\=\frac{7x}{10}+ \frac{5y}{2}+6$

$=\frac{7x}{10}+ 2\frac{1}{2}y+6$

So, Option B is correct.

Gabrielle's age is three times Mikhail's age. The sum of their ages is 92. What is Mikhail's age?

Stolb23 [73]

Answer:

Gabrielle is 69 while Mikhail is 23.

Step-by-step explanation:

Let G represent Gabrielle's age and M represent Mikhail's age.

Gabrielle is three times Mikhail's age. In other words:

$G=3M$

The sum of their ages is 92. In other words:

$G+M=92$

This is a system of equations. Solve. Substitute in G:

$G+M=92\\(3M)+M=92\\4M=92\\M=23$

Thus, Mikhail is 23. Now, find Gabrielle's age:

$G=3M\\G=3(23)\\G=69$

Gabrielle is 69.

The outlier is the piece of data that does not fit the general data set. In this case, 46 is much higher than all of the other numbers. This is the outlier.
