Help please pleassse

ASHA 777 [7]

Answer:

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

Step-by-step explanation:

Multiply both sides of the equation by $\frac{10}{3}$

$(\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})$

Simplify both sides of the equation.

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

A box contains 2 plain pencils and 2 pens. A second box contains 3 color pencils and 5 crayons. One item from each box is chosen

Lapatulllka [165]

Answer:

50% pen first box and 62.5% crayon from second box

Step-by-step explanation:

The first box contains 4 items, 2 of each. This means there are $\frac{2}{4}$ pens. This gives you a $\frac{2}{4}$ chance of picking out a pen. This can be written as 50%.

The second box contains 8 items, 3 color pencils and 5 crayons. This means $\frac{5}{8}$ of the contents are crayons, meaning you have a $\frac{5}{8}$ or 62.5% chance of picking a crayon.

*For working out the percentages, you should convert the fraction to a decimal and then multiply that by 100.

**This content involves fractions, decimals and percentages, as well as basic probability, which you may want to revise. I'm always happy to help!

What is the simplified form of the quantity x over 3 plus y over 4 all over the quantity x over 4 minus y over 3? the quantity 4

STatiana [176]

Answer:

Option A) $\frac{4x+3y}{3x-4y}$

Step-by-step explanation:

The given expression is:

$\frac{\frac{x}{3}+\frac{y}{4}}{\frac{x}{4}-\frac{y}{3}}$

Taking LCM in upper and lower fractions, we get:

$\frac{\frac{x}{3}+\frac{y}{4}}{\frac{x}{4}-\frac{y}{3}}\\\\ =\frac{\frac{4x+3y}{12}}{\frac{3x-4y}{12}}\\\\\text{Cancelling out the common factor 12, we get:}\\\\ =\frac{4x+3y}{3x-4y}$

Therefore, the option A gives the correct answer.
