Answer:

The First one and the third one

Step-by-step explanation:

All you have to do is the distributive property and multiply 7 times 3x and 7 times 2 to get 21x + 14. Then you add like terms for the third one and get x2+5.

Do this help? :)

Which number line shows the correct placement of 20%, 1/3, and 2/3?

BigorU [14]

Answer with Step-by-step explanation:

We are given that

20%

When we change percent into fraction we will divide the percent by 100

$\frac{20}{100}=\frac{1}{5}$

$\frac{1}{3}$

$\frac{2}{3}$

We have to find the line which shows the correct placement of given numbers.

Lcm(3,5)=15

$\frac{1\times 3}{5\times 3}=\frac{3}{15}$

$\frac{1\times 5}{3\times 5}=\frac{5}{15}$

$\frac{2\times 5}{3\times 5}=\frac{10}{15}$
