Answer:

Mia spent 68 dollars.

Step-by-step explanation:

The equation would be 2(13.50) + 4(10.25) = x

Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.

Answer:

Acceleration=3

Step-by-step explanation:

Formula for solving acceleration: F = ma

8N=24

N=3

I think this is correct :)

Answer:

Should be A

Step-by-step explanation:

You going back 3 spaces but than having that three be divided by a positive so it's going to keep going because a negative will make a negative so that positive will be turned into a negative. -3 - 1.5 = -4.5

Answer:

Answer:

False. All triangles must have a total of 180°. 60° + 60° + 70° = 190°.

Answer:

The answer is "x + 4x = 35; 7 large stones and 28 small stones"

Step-by-step explanation:

Please find the complete question in the attached file.

Let

[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]

Users want to use four small stones for each big stone:

[tex]Y = 4x[/tex]

solving the equations system:

[tex]x + y = 35\\\\y = 4x[/tex]

we find:

[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]

Answer:

28.5

Step-by-step explanation:

28.5 delta said it was correct

Answer:

Range = {3, -1, 15}

Step-by-step explanation:

Domain = {0,2,-6}

function : y= -2x + 3

We replace the value of x with domain,

when x = 0

y = -2 × 0 + 3

y = 3

When x = 2

y = -2 × 2 + 3

y = -1

When x = -6

y = -2 × -6 + 3

y= 12 + 3

y = 15

Answer:

D

Step-by-step explanation:

This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.

Answer:

(2x + 7) feet

Step-by-step explanation:

I'm guessing the expression there is

4x² + 28x + 49

4x² +14x +14x +49

Factorize

2x ( 2x + 7) +7( 2x + 7)

(2x + 7)²

Area = (side)1

One side is (2x +7)

Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

Answer:

B

Step-by-step explanation:

Answer:

5.7

Step-by-step explanation:

Step-by-step explanation:

use the formula to be able to find the area of the trapezoid

a = (a+b)÷2 × h

place the numbers into the formula

a = (30+17)÷2 × 22

solve

a = (47)÷2 × 22

a = 23.5 × 22

a = 517 m²

Answer:

4 hours

Step-by-step explanation:

It is 4 hours because you do 36 divide by 12 which is 4, Then you do 4x1= 4

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.

Answer:

35 = 5x ; x = 7

Step-by-step explanation:

plug 7 in for x

35 = 5(7)

35 = 35

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{1}{4}=\frac{percent}{100}[/tex]

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]
