The table shows how much Tracy earns babysitting Saturday nights, depending on how many hours she works

Answer:

x = 8

Step-by-step explanation:

Since the angles are vertical then they are congruent, thus

5x - 5 = 2x + 19 ( subtract 2x from both sides )

3x - 5 = 19 ( add 5 to both sides )

3x = 24 ( divide both sides by 3 )

x = 8

Answer:

8

Step-by-step explanation:

5x - 5 = 2x + 19

3x - 5 = 19

3x = 24

Answer:

76.0 degrees

Just got it right on the Khan Academy quiz.

Answer:

a= -2

b= 1

c= 4

d=0

Step-by-step explanation:

-5 times -2 is 10.

-5 times 1 is -5.

-5 times 4 is -20.

-5 times 0 is 0.

Answer:

Step-by-step explanation:

a = 180 degrees (because they are supplementary, as it says in the given, so their two angles add up to 180 degrees

b = 180 degrees (same reasoning as above)

c = Substitution?

d = m<3

e = m<3

I'm confident with everything except for c. If anyone can fill it in for me, pls do

Answer:

The value that can be subtracted from the area of the rectangle to give the area of the parallelogram = 1/2 × 4.1245 × 0.1085

Step-by-step explanation:

The given parameters are;

The coordinates of parallelogram RSTU are;

R(-4, -3), S(-5, 1), T(4, 3), U(5, -1)

The lengths of the sides are (using an online length calculator);

RS = 4.1231

RT = 10

ST = 9.2195

SU = 10.198

TU = 4.1231

UR = 9.2195

Therefore, by definition of a parallelogram, we have;

RS║TU and ST║UR

The slope of RS = (1 - (-3))/(-5 - (-4)) = -4

The slope of ST = (3 - 1)/(4 - (-5)) = 2/9

The equation of the line perpendicular to ST is therefore;

y - 1 = -9/2×(x - (-5))

y = -9x/2 - 43/2

The equation of RS = y - (-3) = 1/4×(x - (-4)) = x/4 + 1

y = x/4 - 2

The point where the two lines meet is therefore;

-9x/2 - 43/2  =  x/4 - 2

x = -78/19

y = -115/38

The length of the side of the rectangle = 4.1245

The excess width of the rectangle = 0.1085

The value that can be subtracted from the area of the rectangle to give the area of the parallelogram = 1/2 × 4.1245 × 0.1085.

Answer:

y = 1/2x

Step-by-step explanation:

The equation of the straight line shown in the graph is y = 2x.

To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.

From the given graph, the points the straight line is passing through can be found as (2, 1) and (4, 2).

The equation of the line for the given points can be written as follows,

(4 - 2)/(2 - 1) = (y - 2)/(x - 1)

=> y - 2 = 2(x - 1)

=> y = 2x - 2 + 2

=> y = 2x

Hence, the equation of the straight line shown in the graph is y = 2x.

Answer:

15 hours

Step-by-step explanation:

To find the gallons per hour: 230/5=46, this means that it take 46 gallons per hour, you add 46 to 230, and you do that 15 times and you'll get 920. The pool will be filled at 11:00 pm.

Answer:

Options (B), (C) and (E) are the correct options.

Step-by-step explanation:

Equation that represents relation between the number of cars c and the number of vans v to transport 80 students is,

4c + 6v = 80

Option A.

If c = 12,

4(12) + 6(v) = 80

48 + 6v = 80

6v = 32

[tex]v=\frac{16}{3}[/tex]

Which is not equal to 2.

Therefore, Option A is incorrect.

Option B

If c = 14,

4(14) + 6(v) = 80

56 + 6v = 80

6v = 24

v = 4

Therefore, c = 14 and v = 4 is a pair of solutions.

Option B is correct.

Option C.

If c = 6 and v = 11

4(6) + 6(11) = 24 + 66

                 = 90

This means with 6 cars and 11 vans 90 students can be transported. Therefore, there will be extra space.

Option C is correct.

Option D.

If c = 10 and v = 8

4(10) + 6(8) = 40 + 48

                  = 88

Therefore, 10 cars and 8 vans are enough to transport 80 students.

So option D is incorrect.

Option E.

If c = 20,

4(20) + 6(v) = 80

80 + 6v = 80

v = 0

Therefore, for 20 cars go no vans are needed.

Option E is correct.

Option F.

Constraints in this situation,

Minimum number of cars to be used = 20

c ≥ 20

Minimum number of vans to be used = [tex]\frac{80}{6}[/tex] ≈ 14

v ≥ 14

Therefore, Option (F) is incorrect.

C= -8

Step-by-step explanation:

I used a calculator

Answer:

c=-8

Step-by-step explanation:

[tex]\frac{5}{4}c[/tex] + 12 = 2

1.25c + 12 = 2 ( change 5/4 to a decimal for easy understading)

1.25c + 12 - 12 = 2 - 12 ( isolate the variable rememebr whatever you do to the             right do it to the left )

1.25c = -10

1.25c / 1.25 = -10 / 1.25 (divide both sides by 1.25 )

c = -8

Answer:

what is the question that you are asking

Step-by-step explanation:

Answer:

#1

Line A is parallel to line B.

Sorry but I don't think there is a perpendicular line. Line C is y = 5/3x + 2/3 which isn't perpendicular they just cross.

#2

Again none of the lines are parallel which is kind of confusing.

Line A is perpendicular to line B.

Step-by-step explanation:

Answer:

the equation for the line would be x= 4

Step-by-step explanation:

vertical lines means that only the x axis will be crossed by the line

this means that if you have a point of a vertical line, you can take the x value in it to determine the equation

Answer:

Bruno is correct. When going from a larger unit to a smaller unit you need to divide

Step-by-step explanation:

Sam's calculation:

45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 × 0.621 = 77.38 kilometers.

Bruno's calculation:

45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64 kilometers.

1 kilometer = 0.621 miles.

Bruno is correct. When going from a larger unit to a smaller unit you need to divide

We will divide a larger value by a smaller value to get the smaller units
