A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 times Kelly’s. If the total bill is $114.00, how much does each person owe?
Answer:
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Step-by-step explanation:
Let
Kelly's portion = x
Greg's portion = 2x
Joe's portion = 4x - 1.50
Total bill = $114.00
Total bill = Kelly's portion + Greg's portion + Joe's portion
114 = x + 2x + (4x - 1.50)
114 = 3x + 4x - 1.50
114 = 7x - 1.50
Add 1.50 to both sides
114 + 1.50 = 7x - 1.50 + 1.50
115.5 = 7x
Divide both sides by 7
x = 115.5 / 7
= 16.5
x = $16.5
Kelly's portion = x
x = $16.5
Greg's portion = 2x
= 2 × 16.5
= $33
Joe's portion = 4x - 1.50
= 4(16.5) - 1.50
= 66 - 1.50
= $64.5
Therefore,
Kelly owes $16.5
Greg owes $33
Joe owes $64.5

ASK YOUR TEACHER
According to the Bureau of Labor Statistics, in a recent year, there were 16,359,000 women aged 25 to 34 who were employed and 5,309,000
who were unemployed but looking for work. What is the rate per 1,000 women aged 25 to 34 who were employed? Round to the nearest whole
number.
Answer:
The rate of employed per 1000 women is 754
Step-by-step explanation:
Given
Employed = 16,359,000
Unemployed = 5,309,000
Required
Rate per 1000 women of employed
In this case, Rate is calculated by dividing employed by total women
i.e.
[tex]Rate = \frac{Employed}{Employed + Unemployed}[/tex]
[tex]Rate = \frac{16359000}{16359000 + 5309000}[/tex]
[tex]Rate = \frac{16359000}{21668000}[/tex]
Represent the denominator as a factor of 1000
[tex]Rate = \frac{16359000}{21668 * 1000}[/tex]
Divide
[tex]Rate = \frac{754.288086}{1000}[/tex]
Approximate
[tex]Rate = \frac{754}{1000}[/tex]
Hence, the rate of employed per 1000 women is 754

What is the slope of a line that is perpendicular to the graphed line?
Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point [tex]-y[/tex] value of first point) divided by (x value of second point [tex]-x[/tex] value of first point):
[tex]\frac{0-4}{8-0} =-\frac{1}{2}[/tex]
------------------------------------------------------------------------
The slope for a perpendicular line is 2.

If m<2=98, m<3=23, and m<8=70 find the measure of each missing angle
Answer/Step-by-step explanation:
Given:
m<2 = 98,
m<3 = 23,
m<8 = 70
m<1 + m<2 = 180° (linear pair)
m<1 + 98 = 180 (substitution)
m<1 = 180 - 98 (subtracting 98 from each side of the equation)
m<1 = 82°
m<2 + m<3 + m<7 = 180° (sum of angles in a triangle)
121 + m<7 = 180 (substitution)
m<7 = 180 - 121 (subtracting 121 from each side)
m<7 = 59°
m<4 = m<7 (alternate angles are congruent)
Therefore,
m<4 = 59°
m<5 + m<4 + m<3 = 180° (angles on a straight line)
m<5 + 59 + 23 = 180 (substitution)
m<5 + 82 = 180
m<5 = 180 - 82 (subtracting 82 from each side)
m<5 = 98°
m<6 + m<7 + m<8 = 180° (angles on a straight line)
m<6 + 59 + 70 = 180 (subtitution)
m<6 + 129 = 180
m<6 = 180 - 129 (subtracting 129 from each side)
m<6 = 51°
m<9 + m<8 + m<4 = 180° (sum of triangle)
m<9 + 70 + 59 = 180 (substitution)
m<9 + 129 = 180
m<9 = 180 - 129
m<9 = 51°
m<10 + m<9 = 180° (linear pair)
m<10 + 51 = 180° (substitution)
m<10 = 180 - 51
m<10 = 129°

HELPPP QUICK
It should be (2, -9). When rotating 180° you always make the x and y the opposite, so you take the opposite of -2 and the opposite of 9 to get (-2, 9). Hope this helps!
what is the value of x
Answer:
[tex]45[/tex] degrees
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Thus, [tex]x+3x=180[/tex]
[tex]4x=180[/tex]
Divide both sides by 4:
[tex]\frac{4x}{x} =\frac{180}{4}[/tex]
[tex]x=45[/tex]

what are the multiples of 3
Answer:
3,6,9,12,etc
Step-by-step explanation:
In math, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

Write the Linear Equation in Point-Slope Form for a line that has a slope of
-10 and passes through the point (8,2). *
Answer:
y = -10x + 82
Step-by-step explanation:
Plug in the slope and point into y = mx + b to solve for b:
y = mx + b
2 = -10(8) + b
2 = -80 + b
82 = b
Then, plug b and the slope into y = mx + b
y = -10x + 82 is the equation in point slope form.

Does anyone know how to solve this? I really need help please.
Answer:
See Below
Step-by-step explanation:
angle BAK = 128
Find KAS
180 - 128 = 52
KAS = 52
find BKA and ABK
360 -128 = 232
232/2 = 116
BKA =116
ABK = 116
find AKS
180 - 116 = 64
AKS =64
Now you have KAS and AKS
add together and subtract sum from 360 to find BSK
52 + 64 = 116
360 - 116 =244
