Which expression is the factored form of 2/3x+4 ?

frosja888 [35]

Answer:

Option C.

Step-by-step explanation:

The given expression is

$\dfrac{2}{3}x+4$

We need to find the factored form of the given expression.

The given expression can be rewritten as

$\dfrac{2}{3}x+(\dfrac{2}{3}\times \dfrac{3}{2})\times 4$

$\dfrac{2}{3}x+\dfrac{2}{3}(6)$

It is clear that $\frac{2}{3}$ is common.

Taking out common factors, we get

$\dfrac{2}{3}(x+6)$

It is the factored form of the given expression.

Hence, the correct option is C.

the table shows the number of minutes Tim has for lunch and study hall. he calculates that these two periods account for 18% of

EleoNora [17]

Tim spends 500 minutes at the school.

Step-by-step explanation:

Given,

Time for lunch = 45 minutes

Time for study hall = 45 minutes

Total = 45+45 = 90 minutes

This represents 18% of the total minutes Tim spend at school.

Let,

x be the total minutes Tim spend at school.

18% of x = 90 minutes

$\frac{18}{100}x=90\\\\0.18x=90$

Dividing both sides by 0.18

$\frac{0.18x}{0.18}=\frac{90}{0.18}\\x=500$

Tim spends 500 minutes at the school.
