Answer:</h3>
182 1/3 lbs
<h3>
Step-by-step explanation:</h3>
If you don't want to mess with adding and subtracting obscure fractions, you can let your calculator do it.
_____
I find it convenient to add the integer parts separately from the fractional part. Usually, only a slight adjustment is needed at the end.
Integer parts:
... 170 +25 -10 -3 = 182
Fractional parts:
... 2/3 +5/12 -1/4 -1/2 = (8 +5 -3 -6)/12 = 4/12 = 1/3 (added to the above)
Weight after 2 weeks of practice: 182 1/3 lbs.
M= movie cost
v= video cost
Create two equations with the given information. Solve for one variable in equation one. Use that answer to substitute into equation two.
2m+12v=$44
5m+3v=$29
Solve for one variable in equation 1:
2m+12v=44
Subtract 12v from both sides
2m=44-12v
Divide both sides by 2
m=(44-12v)/2
Substitute m answer in equation two:
5m+3v=$29
5((44-12v)/2)+3v=29
(220-60v)/2+3v=29
Multiply everything by 2 to eliminate the fraction
(2)(220-60v)/2+(2)(3v)=(2)(29)
220-60v+6v=58
220-54v=58
Subtract both sides by 220
-54v= -162
Divide both sides by -54
v= $3.00 cost per video
Substitute v value to find m value:
2m+12v=$44
2m+12(3.00)=44
2m+36=44
Subtract both sides by 36
2m=8
Divide both sides by 2
m=$4.00 cost per movie
Check:
5m+3v=$29
5(4.00)+3(3.00)=29
20.00+9.00=29
29=29

Answer:
3/4
Step-by-step explanation:
Number of sections = 8
Number of sections with numbers that are odd = 6
P(odd number)
= 6/8
= 3/4
The altitude of an equilateral triangle is 15.
In order for us to get the area of the equilateral triangle, we need to find the formula first.
Area = square root of (3) / 4 * a^2
Area = square root of (3) / 4 * 15^2
Area = 97.42786 square units.
<span>So the area of the equilateral triangle given the altitude 15 is 97.43 square units.</span>
An equation is formed of two equal expressions. The graph for the given situation can be drawn as shown below.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
The graph for the given equation y=-5x+2 can be drawn as shown below.
