Answer: a = -5
Step-by-step explanation:
-3 (9a+2)=129
-27a -6 = 129
-27a = 129+6
-27a = 135
a = -135/27
Answer: a) 26 guests
b) No, there will be no ice cream left because the result of the division is a exact number.
Step-by-step explanation:
Pints purchased: 19 ½ = (19.2+1)/2 = 39/2
Serve of pint per guest: 3/4
a. How many guests can be served ice cream?
To find out how many guests can be served all we have to do is divide the amount purchased by the amount served per guest:
39/2 ÷ 3/4 = 39/2 * 4/3 = 26 guests
b. Will there be any ice cream left? Justify your answer.
No, there will be no ice cream left because the result of the division is a exact number.

The graph of the solution set for the given system of inequalities can be seen below.
<h3>
How to graph the system of inequalities?</h3>
Here we have two inequalities:
2x + y < 0
y ≥ -4 - 2x
First, we can write both of these in slope-intercept form, to get:
y < -2x
y ≥ -2x - 4
To graph the first one, we need to graph a dashed line along:
y = -2x (we use a dashed line because the symbol < means that the points on the line are not solutions).
And then we shade the region below that line.
For the second one, we need to graph a solid line along:
y = -2x - 4 (this time we sue a solid line, because the points on the line are solutions).
And then we must shade the region above the line.
The graph of the system of inequalities can be seen below. The double shaded region is the solution set for the system.
