Answer 1
23: B, 155.00

D=7 so 5(7)+120 is 155


25: D (2,6)

(X,y) if you plug in the 2 and 6 the equations make sense

26: A (4,1)

Same as 25

27; b, 2x+y=2 and 4x - y=3

The x value and y value have the same value in both equations
Answer 2

Answer:

x + y =5 .......eqn (1)

x - y =3 .......eqn(2)

using substitution method

x + y = 5

-

x - y = 3

0 + 2y=2

y = 2/2

y = 1

substitute y in egn(1)

x + 1 = 5

x = 5-1

x = 4

then (x, y) = (4,1)

5/3y=-(x-5) the slope intercept

Answers

Answer:

y = - [tex]\frac{3}{5}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

[tex]\frac{5}{3}[/tex] y = - (x - 5) ← distribute parenthesis

[tex]\frac{5}{3}[/tex] y = - x + 5 ( multiply through by 3 to clear the fraction )

5y = - 3x + 15 ( divide terms by 5 )

y = - [tex]\frac{3}{5}[/tex] x + 3 ← in slope- intercept form

What is the measure of the angle

Answers

Hey! The measure of the angle is 127

The angle is a total of 180 degrees.

We have to find the total of what's in between the two blue lines.

To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from  53 to 180 individually.

What is M less than A

Answers

I think you mean to ask what is the measure of angle A.

You can find the third angle of the bottom triangle by 180 - 43 - 35 = 102

The vertical angle above it is also 102.

Then, to find the measure of angle A, you do 180 - 102 - 18 = 60

So, the measure of angle A is 60 degrees.

Answer:

60°

Step-by-step explanation:

Since Angle E is same for both triangles, as vertical angles, the sum of the other two interior angles should be same.

Then we have:

m∠A + m∠B = mC + m∠Dm∠A + 18 = 43 + 35m∠A + 18 = 78m∠A = 78 - 18m∠A = 60

A truck can be rented from Company A for ​$140 a day plus ​$0.30 per mile. Company B charges ​$80 a day plus ​$0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

Answer:

800 miles

Step-by-step explanation:

140 + (0.30 x 800) = 400$, 800 miles

80 + (0.40 x 800) = 400$, 800 miles

Agatha drives 73 1/2 miles through two towns in 2 1/3 hours. What is her average speed in miles per hour?

Answers

Answer:

31 1/2

Step-by-step explanation:

average speed = distance/time

average speed = (73 1/2 miles)/(2 1/3 hours)

= (147/2 miles)/(7/3 hours)

= 147/2 * 3/7 miles/hour

= 441/14 miles/hour

= 31 1/2 miles/hour

Using the line of random numbers to run one simulation,
what proportion of students tried out for a sport?
O 0.40
A study reported that about 40% of high school students
have tried out for a sport at their school. To find out if this
applies to Jessica's school, she surveyed an SRS of 20
students. Nine of them said that they had tried out for a
sport. To see if this result is surprising, a simulation is to
be conducted to estimate the probability of obtaining a
sample result as high as this one.
Let 0-3 represent students who tried out for a sport and
4-9 represent students who did not try out for a sport.

Using the line of random numbers to run one simulation, the proportion of students that tried out for a sport is .4

Calculation and Parameters:

Given that 40% of students tried out for a sport in a school

The survey is an SRS of 20 students.

Hence, to find the proportion of students that tried out for a sport with the use of a line of random numbers would be:
