Answer:

11 [tex]\frac{3}{8}[/tex] miles.

Step-by-step explanation:

To find how many miles Brandon rode, we can create an equation in slope-intercept form: y = mx + b

$2.25 is the flat fee, or the unchanging variable. This is our y-intercept, or b.

$0.40 is the changing variable, as it changes value depending on the amount of miles ridden. This is our slope, or m.

We know Brandon spent $6.80 on the cab ride. So, this is our y.

We get the equation: 6.80 = 0.40x + 2.25.

To solve, first subtract 2.25 from both sides of the equation:

6.80 - 2.25 = 0.40x + 2.25 - 2.25

We get: 4.55 = 0.40x

Now, just divide by 0.40 on both sides:

4.55 ÷ 0.40 = 0.40x ÷ 0.40

We get: 11.375 = x

So, Brandon rode for 11.375 miles. When converted to a mixed number, we get 11 [tex]\frac{3}{8}[/tex] .

Answer:

[tex]18e^2f^3-12e^2f = 6e^2f(3f^2-2)[/tex]

Step-by-step explanation:

Given

[tex]18e^2f^3-12e^2f[/tex]

Required

Factorize:

[tex]18e^2f^3-12e^2f[/tex]

Express 18 as 6 * 3 and 12 as 6 * 2

[tex]18e^2f^3-12e^2f = 6*3e^2f^3-6*2e^2f[/tex]

Factor out 6

[tex]18e^2f^3-12e^2f = 6(3e^2f^3-2e^2f)[/tex]

Factor out [tex]e^2[/tex]

[tex]18e^2f^3-12e^2f = 6e^2(3f^3-2f)[/tex]

Factor out f

[tex]18e^2f^3-12e^2f = 6e^2f(3f^2-2)[/tex]

0.29629629629in³

Step-by-step explanation:

To find the volume of a cube you multiply the length by the width by the height. Since all the sides of the cube are the same, its the same measure multiplied three times, ie. to the power of three.

(2/3)³=0.29629629629in³

Answer:

(45,9), (50, 14)

Step-by-step explanation:

the y-axis' pattern is subtract 2 and add 5.

the x-axis' pattern is add 7 then add 5.

So we get (45, 9) and (50, 14)

Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

Equation: 68.50=48+5x Answer: 4gigabytes

Step-by-step explanation:

You have to add the flat cost and the cost per gigabyte together. Then set it equal to her maximum amount and solve.

The equation to calculate the number of gigabytes will be 68.50=48+5x. The number of gigabytes will be 4.1 GB

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that under her cell phone plan, Autumn pays a flat cost of $48 per month and $5 per gigabyte. She wants to keep her bill at $68.50 per month.

The expression can be written as below:

68.50=48+5x

5x = 68.5 - 48

5x = 20.5

x = ( 20.5 / 5 ) = 4.1 Gb

Therefore, the equation to calculate the number of gigabytes will be 68.50=48+5x. The number of gigabytes will be 4.1 GB

Answer:The answer is going to be 3 and this is how we came to that determination:

We are to subtract 3 times the number from 7 times the number and have it equal 12. So here is the the mathematical sentence to help us get the answer:

7X-3X=12 ; now we are going to subtract the 3 from the 7 on the left hand side of the equal sign:

4X=12 ; now we will divide each side of the equal sign by 4:

4X/4=12/4 and get X =3 ; to prove 3 is the number we are looking for, we will substitute it for X in our original sentence:

7(3)-3(3)=12

21–9=12

12=12

3 is our answer.

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

Answer:

39,055

Step-by-step explanation:

so you say 6 over 100 multiplied by $36,500 over 1. then 100 into 36,500 then you get 365. then you say 6 multiplied by 365 and you get 2,555. then you say 2,555 plus 36,500 then you get 39,055

Answer:

x = 20

Step-by-step explanation:

4(x + 7) - 5x + 2 = 10

open the parenthesis

4 * x + 4 * 7 - 5x + 2 = 10

4x + 28 - 5x + 2 = 10

combine like terms

-x + 30 = 10

subtract 30 from both sides of the equation

-x + 30 - 30 = 10 - 30

-x = 10 - 30

-x = -20

mutiply the equation by -1

-1 * -x = -20 * -1

x = 20

[tex]y = -\frac{5}{2}x +6[/tex]

Step-by-step explanation:

Given

[tex]m = -\frac{5}{2}[/tex] -- slope

[tex](x_1,y_1) = (2,1)[/tex] --- point

Required

Determine the line equation

In slope intercept form, a line equation is:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 1 = -\frac{5}{2}(x - 2)[/tex]

Open bracket

[tex]y - 1 = -\frac{5}{2}x +5[/tex]

Add 1 to both sides

[tex]y - 1+1 = -\frac{5}{2}x +5+1[/tex]

[tex]y = -\frac{5}{2}x +6[/tex]
