Answer:
8 hours
Step-by-step explanation:
Let x = the hours she work
Equation-
1. 20x + 12 = 172
2. - 12 - 12
20x = 160
3. /20 /20
4. x= 8 hours
1. Write out the equation
2. subtract 12 from both sides
3. Divide 20 on both sides
4. Your answer is 8 hours
Answer:
Number line graph with closed circle on 24 and shading to the right.
Step-by-step explanation:
First, the graph has to have a closed circle on only 24.
Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.
This means the last 2 answer choices are wrong, because there cannot be shading in between.
The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.
So, the correct answer is Number line graph with closed circle on 24 and shading to the right.
Answer:
y=3x-4 is the slope-intercept form of the equation of a line. It is in the form y=mx+b.
m is the slope (often called "rise over run") and b is the y-intercept (the point where x=0).
The y-intercept is the point (0,-4).
We need one other point. This is where finding easy calculations pays off. How about where x=2, y=(3)(2)-4 = 2.
That's the point (2,2).

Refer to the attached image.
Given:
The measure of 
and 
.
Also, Three rays ML, MK, and MJ share an endpoint M. Ray MK forms a bisector as shown in the attached image and the bisector divides angle JML into two parts.
To Prove: 
is a right angle.
Proof:
Statements Reasons
1. 
Given
2. 
Given
3. 
The reason for statement 3 is Angle addition postulate. As angle JML is composed of 2 angles that is angle JMK and angle KML. So by adding the measures of angles JMK and KML, we will get the measure of angle JML which is referred as Angle addition postulate.
4. 
Substitution property of equality
5. 
Simplification
6. 
JML is a right angle. Definition of right angle
