Answer:

Y = 6

Step-by-step explanation:

On the first day of ticket sales the school sold 3 adult ticket and 8 student tickets for a total of $72. The school took in $152 on the second day by selling 7 adult tickets and 16 student tickets. How much is a student ticket?  

Day 1: 3x + 7y = 72

Day 2: 7x + 16y = 152

This becomes a system of equations.

3x+8y=72

3x+8y+−8y=72+−8y (Add -8y to both sides)

3x=−8y+72

3x/3 =  −(8y+72)/3

X = (-8/3) y + 24

Substitute  (-8/3) y + 24 for x in7x+16y=152:

7(-8/3 y + 24) + 16y = 152

-8/3 y + 168 = 152 (Simplify both sides of the equation)

-8/3 y + 168 − 168 = 152 + (−168) (Add -168 to both sides)

-8/3 y = -16

(-8/3 y)/(-8/3 y) = -16/ -8/3 y (Divide both sides by (-8)/3)

y = 6

Answer:

y=5x + 21

Step-by-step explanation:

y=5x×b

6= -15+b

b=21

Answer:

I think the answer to X = 11.

Step-by-step explanation:

X - 2 = 9, correct?

11 - 2 = 9.

I hope this can help! Please correct me

Step-by-step explanation:

Answer:

14 m

Step-by-step explanation:

Speed = 28 mph

Time = 30 minutes = 30/60 = 1/2 hour

Distance  = speed * time

               = 28 * [tex]\frac{1}{2}[/tex]

                = 14 m

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Student : teacher = 5 : 2

Number of students = 5x

Number of teachers = 2x

Last year:

Last year Total  = 56

5x+  2x = 56

       7x = 56

        x = 56/7

x = 8

Number of students = 5*8 = 40

Number of teachers = 2*8 = 16

This year:Total = 70

5x + 2x = 70

       7x = 70

        x = 70/7

x = 10

Number of students = 5*10 = 50

Number of teachers = 2*10 = 20

Answer:

  (x+ (-4), y+ (-4))

Step-by-step explanation:

After point D is reflected across the y-axis, its coordinates are ...

  D(-1, 2) ⇒ D'(1, 2)

This is the point that gets translated to F(-3, -2). The translation is ...

  F -D' = (-3, -2) -(1, 2) = (-3-1, -2-2) = (-4, -4)

Then the translation rule is ...

  (x, y) ⇒ (x+(-4), y+(-4))

Given:

The two points are (0, -2) and (9, 10).

To find:

The distance between the given points.

Solution:

Distance between the two points is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the above distance formula, the distance between given points is

[tex]d=\sqrt{(9-0)^2+(10-(-2))^2}[/tex]

[tex]d=\sqrt{(9)^2+(10+2)^2}[/tex]

[tex]d=\sqrt{81+(12)^2}[/tex]

On further simplification, we get

[tex]d=\sqrt{81+144}[/tex]

[tex]d=\sqrt{225}[/tex]

[tex]d=15[/tex]

Therefore, the distance between the given points (0,-2) and (9,10) is 15 units.

Step-by-step explanation:

Two angles are called suplementary when their measures add to 180 degrees.

D+F= 180

3x+5+2x= 180

5x+5=180

5x= 175

x= 35°

angle D = 3x+5= 3(35)+5= 110°

Answer:

I think B but Im not 100% sure

Answer:

300

Step-by-step explanation:

→ First substitute the biggest number into it

45% of 300 =

→ Do 45  × 300

13500

→ Divide answer by 100

135

→ Therefore 45% of 300 = 135

Answer:

3/1

Step-by-step explanation:

Line is passing through the points (0, 0) and (1, 3)

Slope of the line

Answer:

9

Step-by-step explanation:

because the paragraph is telling you 9 of the 18 customers want mustard on their hot dog so the paragraph is telling you de answer

Answer:

57

Step-by-step explanation:

First, write the experimental probability as a fraction in simplest form.

P(mustard)

=

mustard

total

=

mustard

mustard+other

=

30

30+10

=

30

40

=

3

4

The experimental probability is

3

4

.

We can predict the outcome of the second set of trials by assuming that the ratio will be the same as in the first set of trials. Write a proportion by setting the two ratios equal to each other, then solve.

3

4

=

n

76

3

4

(476)

=

n

76

(476) Multiply both sides by (476)

376

= 4n Simplify

228

= 4n Simplify

57

= n Divide both sides by 4

You would expect 57 of the next 76 customers to want mustard.

Answer:

A. is ur answer

Step-by-step explanation:

the rate of change for Jack is 7 points increased for each additional hour studied and the rate of change for Howie is 6 points increased per hour so 7-6 is equal to 1.

hope this helps <3

Answer:

6ft tall

Step-by-step explanation:

Given we know that the scale is 1 in 2ft.

Using this information we know we could divide 12/2=6. We also know that we could multiply 2×6=12. Therefore, we know that the model plane is 6ft tall.
