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°

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

Answer:

y = 8

Step-by-step explanation:

Step 1: Write equation

3 - 5y = -37

Step 2: Subtract 3 on both sides

-5y = -40

Step 3: Divide both sides by -5

y = 8

Answer:

The common factor is (3x+1).

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.

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

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

Let me know if incorrect, plz.

Hope this helps=)

20+7

add the numbers 20 and 7

so the number 4 is not the solution

Answer:

$79.20 savings.

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!

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]

Thus, [tex]x+3x=180[/tex]

[tex]4x=180[/tex]

Divide both sides by 4:

[tex]\frac{4x}{x} =\frac{180}{4}[/tex]

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.
