Answer:
11+x^2/3

Explanation:
“Eleven more” means you add 11 somewhere in the expression.

11+

The “quotient” is the answer to a division problem, so “the quotient of a number squared and three” translates to the answer to a number squared divided by 3.

11+x^2/3

“A number” in the question would be x, because it’s the unknown value.

I hope this helps!

2/-3 divided by -1 2/7 = <br> pls explain the answer

katen-ka-za [31]

Answer:

$\frac{14}{27}$

Step-by-step explanation:

$-1\frac{2}{7} = -\frac{9}{7}$
Plug -9/7 in: $-\frac{2}{3}$ ÷ $-\frac{9}{7}$
-2/3 ÷ -9/7 = 2/3 ÷ 9/7 = 2/3 × 7/9
$\frac{2}{3}$ × $\frac{7}{9} = \frac{14}{27}$

Are the angles complementary, supplementary, or neither? What's the answer? Photo below.

I personally would say neither because they either aren't the same or there not equivalent.
