5 0

Answer:

-27

Step-by-step explanation:

Any operations inside parentheses must be carried out first.

Thus,

9 ÷ 3[(20 − 7) − 22] becomes 9 ÷ 3[(13) − 22]

This, in turn, becomes 9 ÷ 3[-9].

The negative operator can be taken out and written up front:  -9 ÷ 3[9) Note:  this does not call for subtraction).

Carrying out the indicated operations from left to right:

-3(9) = -27

Find m∠Y if m∠Y is six more than three times its supplement.
Svetlanka [38]
To answer this item, we let x be the measure of angle Y. If we say supplement, it is understood that when we sum up the measures of the two angles (angle Y and its supplement) the answer should be 180. Therefore the other angle is 180-x. Going back to the condition given in this item, we will be able to generate an equation,
                                         x = 3(180 - x)
The value of x from the equation is 135. Thus, m∠Y is 135°.
