Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5

Solve for varible
-7y=91
a/9=-4
-1/2m=-9
Answer:
y = -13
a = -36
m = 18
Step-by-step explanation:
-7y=91
divide both sides by -7
-7y/-7 = 91/-7
y = -13
a/9=-4
multiply both sides by 9
9(a/9) = 9(-4)
a = -36
-1/2m=-9
multiply both sides by 2
2(-1/2m) = 2(-9)
-1m = -18
divide both sides by -1
m = 18

"ally became a waiter at a fancy restaurant. She makes $9 per hour. One night she made $150 in tips. How many hours did she work if he made a total of $226.50."
Variable: x = hours
Equation: __________________
Work:
Solution: x = ______ hours
Answer:
226.50 - 150 = 76.5 divided by 9 = 8.5 hours
Step-by-step explanation:
Answer:
8.5 hours
Step-by-step explanation:
First, you need to subtract 226.50 and 150 which gives you 7.65. After that, you need to divide 76.5 by 9 which will give you 8.5 hours. I hope this helps

Answer:
The interquartile range (IQR) of the data set is:
3.5
Step-by-step explanation:
The data points are given as follows:
0, 1 1/2, 2 1/2, 3, 4, 4, 4, 7, 7 1/2
i.e. 0 , 1.5 , 2.5 , 3 , 4 , 4 , 4 , 7 , 7.5
There are a total of 9 data points and we know that the median of the data is the central tendency of the data and it always exist in the middle of the data.
Here we have 9 data points.
and hence the median exist at the the 5th place.
Hence, Median of data of Middle quartile i.e. = 4
Also, the lower set of data is:
0 , 1.5 , 2.5 , 3
and the first quartile or the lower quartile i.e. is the median of the lower set of data.
i.e.
The upper set of data is:
4 , 4 , 7 , 7.5
and the third quartile or the upper quartile i.e. is the median of the upper set of data.
i.e.
Hence, the interquartile range (IQR) of the data set is given by

Answer:
144 or 72^2
Step-by-step explanation:
You have one leg a 5 and the other leg we don't know, well we know the hyponuse is a 13.
So the first step is
A^2 + B^2 = C^2
2 step,
5^2 + B^2 = 13^2
3 step
5 x 5 = 25 and 13 x 13 = 169
25 + B^2 = 169
4 step
169 - 25 = 144
144 divided by 2 is 72, so 72 x 72 is 144.
If you have an answer 72 squared or 144 both will work.
It does not help that you don't give the answers.

As they are right angle triangles and 2 lines are perpendicular.
To find height of any shape we look for perpendicular line this also applies to segments.
Segments as seen below can only be cut off areas of a circle by either a chord touches line as shown second picture, or a secant which is a perpendicular use line . and crosses the line of the circle but is not shown in picture only the chord is.
Secant line still forms a segment but is only used usually with overlapping shapes some which are parallel in geometry solving for tangents or shading.
Answer:
1stB = 2nd H
2ndB = 3rd H
3rdB = 1st H

Answer: 1 is 1,3
Step-by-step explanation:
Please help how do you solve this?
Answer:
A, 120 degrees
Step-by-step explanation:
=============================================================
Explanation:
Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.
The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.
Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees
------------
Or another method you could use is the fact that all exterior angles of any polygon add to 360.
Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees
We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.
