Step 2: Flip the equation.

9r+9=−18

Step 3: Subtract 9 from both sides.

9r+9−9=−18−9

9r=−27

Step 4: Divide both sides by 9.

9r /9  =-27/9

One car rental company charges $35 for the rental, plus $2 per mile driven. A second rental car company charges $20 for the rental, plus $5 per mile driven. At how many miles will the two companies cost the same?

Answers

Answer:

b

Step-by-step explanation:

For 5 miles will the two companies cost the same.

What is an expression?

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

Given that;

One car rental company charges $35 for the rental, plus $2 per mile driven.

A second rental car company charges $20 for the rental, plus $5 per mile driven.

Now,

Let distance for the two companies cost the same is x miles.

Then, for first condition we can formulate;

Total cost for x miles = $35 + $2x

And, For the second condition;

Total cost for x miles = $20 + $5x

So, For distance of the two companies which has cost the same;

$35 + $2x = $20 + $5x

$35 - $20 = $5x - $2x

$15 = $3x

x = 5

Thus, For 5 miles will the two companies cost the same.

Convert 214 pounds to kilograms. Use 1 kg = 2.2 lb.

Answers

So what I did was divide 214 by 2.2 and got 97kg

Answer:

97.27 kg

Step-by-step explanation:

1kg = 2.2 lb

214 lb = ?kg

Make it into an equation:

1 kg/ 2.2 lb = ?kg / 214 lb

? = 1kg x 214lb ÷ 2.2 lb

?= 214lb ÷ 2.2 lb

? ≈ 97.27 kg / 214 pounds

Verify :

97.27 x 2.2 ÷ 214 ≈ 0.99 ≈ 1 kg

What is Displacement in wave?

The relative shift in a wave's position that occurs when it passes through a medium is referred to as wave displacement.

When a wave oscillates, displacement is the movement of a particle or field relative to its resting location. The amplitude of the wave is a measurement and recording of the largest displacement that has place.

Given:

From the graph we can a wave.

Now, we can see that the Wave is 2 inches in crust and 2 inches in trough.

So, the weight travel from maximum displacement to minimum displacement is

Answer:

x = 5

Step-by-step explanation:

Given

4x - 3 = 2x + 7 ( subtract 2x from both sides )

2x - 3 = 7 ( add 3 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Answer:

x=5

Step-by-step explanation:

you will start by subtracting 2x from 4x then you are left with 2x-3=7. then you will add 3 to 7 that will give you 2x=10, then divide 2 from 10. from there you get x=5.

[tex]\boxed {x = 0.8}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]4x + 8 = 7.2 + 5x[/tex]

-Take [tex]5x[/tex] and subtract it from [tex]4x[/tex]:

[tex]4x + 8 - 5x = 7.2 + 5x - 5x[/tex]

[tex]-x + 8 = 7.2[/tex]

-Subtract [tex]8[/tex] to both sides:

[tex]-x + 8 - 8 = 7.2 - 8[/tex]

[tex]-x = -0.8[/tex]

-Divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} = \frac{-0.8}{-1}[/tex]

[tex]\boxed {x = 0.8}[/tex]

So, the value of [tex]x[/tex] is [tex]0.8[/tex].

The solution of the given expression is x = 0.8.

We are given that;

The expression 4x+8=7.2+5x

Now,

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

To solve for x, we can use the following steps:

- Subtract 4x from both sides: 4x + 8 = 7.2 + 5x - 4x - 4x

- Simplify: 8 = 7.2 + x

- Subtract 7.2 from both sides: 8 - 7.2 = 7.2 + x - 7.2

- Simplify: 0.8 = x

Therefore, by expression the answer will be x = 0.8.

Write an equation that you can use to find the number of refills Keith bought. A restaurant sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month Keith spent $31.75 on a mug and refills. (use x for your variable and do not use $ in your answer) *

Answers

Answer:

6.75+1.25x=31.75

Step-by-step explanation:  

let x be the number of refils

also given is that the cost of one refill is $1.25

hence the total refil will be 1.25x

given that the cost of a mug is $6.75

6.75+1.25x=31.75

therefore  the expression that can be used to solve for the number of refills is

6.75+1.25x=31.75

Answer:

x = 20

y = 25

Step-by-step explanation:

Vertical angles are always congruent, that is a theorem.

Set the vertical pairs equal to each other.

182 - 4x = 5x + 2

The lowest of the two coefficients is 4x, so that will be added to both sides.

4x + 5x = 9x

Simplify

9x + 2 = 182

Subtract both sides by 2

9x = 180

Divide by 9

180/9 = 20

x = 20

Plug in the 20 to get the angle measure.

182 - 80 = 102

the vertical pairs are 102 degrees

There is another theorem that sets the two angles outside as congruent.

So set 4y + 2 = 102

Subtract 2

Step-by-step explanation:

0.04 is equal to [tex]\frac{4}{100}[/tex]. You can simplify this when both the numerator (the top number of the fraction) and the denominator (the bottom number of the fraction) can be divided by the same number. In this case, both numbers can be divided by 4, which would simplify it to its lowest form: [tex]\frac{1}{25}[/tex].
