Answer:

(-1, -8)

Step-by-step explanation:

So you would do the simplifying by "subtracting" the equations from each other. So to isolate the x, you could subtract the y away.

   8x + y = -16

  -3x + y = -5

-___________

11x = -11

x = -1

Then, substitute x into either equation.

8(-1) + y = -16

-8 + y = -16

Isolate y.

y = -8

Denote shirts by x and pants by y
So 3x +2y=120
6x +3y=213
Add -2 to top function
-6x -4y=-240
6x +3y=213
Cancel-6 and 6
Add the rest
-1y=-27 cancel negatives
Y=27
3x+2*27=120
3x=66
X=22
Shirt costs $22
Pants costs $27

Complete arithmetic sequence?

92, ___, ___ ,___, 80

Answers

Answer:

433333333333

Step-by-step explanation:

The complete arithmetic sequence will be 92, 89, 86, 83, and 80.

What is an arithmetic sequence?

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The first term (a₁) is 92 and the fifth term (a₅) is 80.

Then the common difference between the terms will be given as,

a₅ = a₁ + (5 - 1)d

80 = 92 + 4d

-12 = 4d

d = -3

Then the missing terms will be

92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12

92, 89, 86, 83, and 80

Thus, the complete arithmetic sequence will be 92, 89, 86, 83, and 80.

More about the arithmetic sequence link is given below.

Answers

Answer:

W = 20 (woman's age)

M = Man's age

W = Woman's age

M + 20 = 2(W + 20)

Sub for M

Answer:

[tex]a = 8.5t[/tex]

[tex]y = 32.55[/tex]

Step-by-step explanation:

Solving (9): The equation of the table

We start by calculating the slope (m)

[tex]m = \frac{a_2 - a_1}{t_2 - t_1}[/tex]

Where:

[tex](t_1,a_1) = (15,127.5)[/tex]

[tex](t_2,a_2) = (16.5,140.25)[/tex]

[tex]m = \frac{140.25 - 127.5}{16.5 - 15}[/tex]

[tex]m = \frac{12.75}{1.5}[/tex]

[tex]m = 8.5[/tex]

The equation is then calculated using:

[tex]a = m(t - t_2) + a_2[/tex]

So, we have:

[tex]a = 8.5(t - 16.5) + 140.25[/tex]

Open bracket

[tex]a = 8.5t - 140.25 + 140.25[/tex]

[tex]a = 8.5t[/tex]

Solving (10):

[tex]4.8y = 156.24[/tex]

Required

Find x

Divide both sides by 4.8

[tex]y = 32.55[/tex]
