Answer:

2 students are wearing shirts other than blue shirts or white shirts.

Step-by-step explanation:

3/10 of 20 is 6, so 6 people are wearing blue shirts. 3/5 of 20 is 12, so 12 students are wearing white shirts. 6 + 12 = 18. 20 - 18 = 2.

A) 12 x - 18 = 4x + 30

olga55 [171]

Answer:

x = 6

Step-by-step explanation:

You add 18 to both sides so that the equation turns into 12x = 4x + 48

Then you subtract 4x from both sides so that the equation becomes 8x = 48

Then you divide both sides by 8 and get x = 6

Help please and thank you

Remember
$(a^b)^c=a^{bc}$
and
$\frac{x^a}{x^b}=x^{a-b}$

so

$\frac{(7^2)^5}{7^{-6}}=$
$\frac{7^{2*5}}{7^{-6}}=$
$\frac{7^{10}}{7^{-6}}=$
$7^{10-(-6)}=$
$7^{10+6}=$
$7^{16}$

the answer is D
