Answer:

x = 9

Step-by-step explanation:

-5(1 + 1x) = -50

-5 + -5x = -50

-5 + -5x + 5 = -5x

-50 + 5 = -45

-5x = -45

-5x / -5 = x

-45 / -5 = 9

x = 9

Answer:

Answer:

2m + 3.10 = 21.10

m = 9

Step-by-step explanation:

First Step

2m + 3.10 =21.10

Subtract 3.10 from both sides

Second Step

2m = 18

Divide 2 from both sides

m = 9

The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Here,

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up fee $3.10 plus $2 per mile. The total fare was $21.10.

Now,

The equation is written as,

2m + 3.10 = 21.10

Subtract 3.10 from both sides

2m = 18

Divide 2 from both sides

m = 9

Hence, The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Answer:

RS = 45.9 feet

Step-by-step explanation:

Let the length of RS be represented by x. In the given triangle applying the required trigonometric function, we have;

Cos θ = [tex]\frac{Adjacent}{Hypotenuse}[/tex]

Cos 54 = [tex]\frac{27}{x}[/tex]

⇒ x = [tex]\frac{27}{Cos 54}[/tex]

      = [tex]\frac{27}{0.5878}[/tex]

x = 45.9340

x = 45.9 feet.

The length of RS in the given triangle is 45.9 feet.

6x28=168

To earn atleast $168, Hermes should do babysit for atleast 28 hours.

Inequality is just like an equation showing relationship between two or more variables but this is expressed in greater than ,less than form.

It defines a range of value of the relationship.

We have been given that Hermes earns $6 per hour for babysitting and he wants to earn atleast $168 for a new video game. We have to calculate the minimum number of hours that he should do babysit in order to earn $168.

We know that total revenue will be number of hours* payment of 1 hour.

let the number of hours that he does babysit is x.

The inequality will be :

6x>168

x>168/6

x>28

Hence to earn atleast $168 he should work for atleast 28 hours.
