<h3>
Answer:</h3>
The first line.
<h3>
Step-by-step explanation:</h3>
If we let x represent "a number", then "a number divided by 3" is x/3. The denominator is missing on the first line.
Further, this "is 4 more than -11", so is = 4 + (-11). The constant 4 is on the wrong side of the equal sign in line 1.
_____
The solution should be ...
... x/3 = 4 + (-11)
... x = 3·(-7)
... x = -21
___
<u><em>Check</em></u>
-21 divided by 3 is -7. That is 4 more than -11.
The equation for profit is expected to be
daily profit = (profit on plate)*(number of plates) +(profit on cup)*(number of cups)
We are told that
profit on plate = k
profit on cup = k-1
Matching these to the expression above, we find
x = number of plates
y = number of cups
You are asked what y represents. It is
A. The number of cups sold in one day.
Let me know if this helps you.
Step-by-step explanation:
question 15
For y to be parallel to z the sum of given angles must be equal to 180°
3x + 7 + 10x - 22 = 180° add like terms
13x - 15 = 180 add 15 to both sides
13x = 195 divide both sides by 13
x = 15
question 16
If y is parallel to z then the given angles are alternate exterior and has same measurement
11x - 3 = 4x + 39
11x - 4x = 39 + 3
7x = 42 divide both sides by 7
x = 6
