Answer:

Step-by-step explanation:
Solve the system of inequalities:
x + 4 < 0
OR:
6x > -12
The first inequality yields the solution:
x < -4
The second inequality gives the solution:
x > -2
The total solution is the disjunction of the individual solutions, i.e., the union of both.
It can be expressed as

Day 1:
5 haircuts @ $25.75 = $128.75
3 Color treatments @ $40.50= $121.5
Total =$250.25 per day
$250.25 x 6 days =$1,501.50
The value 600 is 30 times as much as 20
<h3>Ratio and proportion</h3>
Ratio are written in terms of fractions. The expression 600 is how many times as much as 20 can be written as;
600 = x *20
where x is the required value or factor
20x = 600
Divide both sides by 20
20x/20 = 600/20
x = 30
Hence the value 600 is 30 times as much as 20

Answer:
15) For a regular polygon of N sides, the measure of one interior angle is:
A = (N - 2)*180°/N
In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:
A = (11 - 2)*180°/11
A = 9*180°/11 = 147.27°
Rounding to the first decimal after the decimal point, we get:
A = 147.3°
Then the correct option is B.
16) We know that the length of all the sides of a square is the same.
In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4
And those lengths must be the same, then we have the equation:
2x + 4 = 4
subtracting 4 in each side of the equation we get:
2x + 4 - 4 = 4 - 4
2x = 0
The only solution for this equation is x = 0.
Then the correct option is C
