Answer:

c = 8+5n

total cost of 13 tickets = $68

Step-by-step explanation:

c = 8 + 5(12)

c = 8 + 60

c = 68

(i put 12 because were already adding 8 for that ONE ticket)

Step-by-step explanation:

Answer:

dimes = 32

quarters = 8

Step-by-step explanation:

set up a system of equations:

let d = # of dimes

let q = # of quarters

d + q = 40

.10d + .25q = 5.2

substitution method; let 'q' = 40 - d

.10d + .25(40 - d) = 5.2

.10d + 10 - .25d = 5.2

-.15d = -4.8

d = 32

q = 40 - 32 = 8

Answer:

Step-by-step explanation:

32 dimes

8 quarters

Answer:

48

Step-by-step explanation:

4x=148+44

4x=192

x=48

Answer:

Step-by-step explanation:

there are 360 degrees inside any 4-sided polygon

so add all four angle measures and set equal to 360:

3x + x + 44 + 148 = 360

4x + 192 = 360

4x = 168

x = 42

check:

3(42) + 42 + 44 + 148 should equal 360

126 + 42 + 192 = 360

168 + 192 = 360

360 = 360

Answer:

Y = 40

X = 101

W = 20

Step-by-step explanation:

All of the triangles Angles should equal 180!

Answer:

slope of AB = 4

slope of CD = 4

Step-by-step explanation:

We simply use the slope formula for this;

The slope formula is;

m = (y2-y1)/(x2-x1)

for AB, we have;

m = (3+1)/(6-5) = 4

For CD, we have

m = (-1-3)/(1-2) = -4/-1 = 4

Answer:

Step-by-step explanation:

1). Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

   m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   Therefore, slope of the line passing through two points (2, -10) and (-2, 18) will be,

   m = [tex]\frac{-10-18}{2+2}[/tex]

  m = -7

2). From the table attached,

    Slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

    Slope of line passing through (4, -6) and (0, -2) will be,

    Slope = [tex]\frac{-6+2}{4-0}[/tex]

    Slope = -1

9514 1404 393

Answer:

  36

Step-by-step explanation:

The sum of the tangent segments shown is ...

  6 + 3 + 9 = 18

The unmarked tangent segments will have the same measure to the same vertex as the marked tangent segments. The perimeter is ...

  2 × 18 = 36 units

Answer:  2 vertices

The two vertices in question are (2,0) and (5,0). These are points A and D. These two points are on the x axis, which is the line of reflection. Any point on a line of reflection does not move.

The points (0,-3) and (3,-3) are not on the line of reflection, so they do move and are reflected to another location. Refer to the diagram below.

Answer:

Social Security = $385.83

Medicare = $90.23

Step-by-step explanation:

Social security rate in 2021 is 6.2% on your first $142,800 for the year. Shelly has not reached that threshold so her Social security tax is:

= 6.2% * 6,223

= $‭385.83

Medicare has no threshold and the rate in 2021 is 1.45%:

= 1.45% * 6,223

= $90.23

Answer: 40 times

Step-by-step explanation:

Given: Total planks = 20

By using integers, Steps forward is represented by +5, Steps backward s represented by  -4.

After first set of two steps ( one forward another backward), 5-4 =1 step forward is captured.

For 20 planks , we require 20 such sets, i.e. he will do this 2x 20 times i.e. 40 times.

Hence, he will do this 40 times to reach the other side.

Answer:

144

Step-by-step explanation:

Answer:

No, because not all of the pairs represent the same ratio. ...

Answer:

For an equation like:

y = a*x + b

a is the slope, and this is the rate of change of the function.

For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.

Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.

Step-by-step explanation:

We have

Summer membership + $12 = 3(Weekend pass).

=> ($78) + ($12) = 3x

=> 3x = $90

=> x = $30.

Hence the weekend admission is $30.

Answer:

3x-12=78

Step-by-step explanation:

This is my thinking:

So because x is the cost of the weekend admission, the problem says 12 less than 3 times the cost of the weekend admission. The 3 times the cost of the weekend admission is the 3x, and the problem says 12 less than and that is the -12. And the whole equation is being taken from 78, so

3x-12=78.
