A bike rental charges a flat fee of $500. As well as $0.05 every mile. If you spent$10 how many miles did you take the bike for? Write and solve an equation for this problem

Answers

Answer: 100 miles.

Step-by-step explanation:

Here , Flat fee = $ 5.00

Additional charge per mile = $ 0.05

Money spent = $ 10

Formula : Total Charge =  Flat fee + (Number of miles ) x (Additional charge per mile)

Let x= Number of miles

Substitute values , we get

10 = 5 + 0.05x

⇒ 0.05x= 5

⇒ x = 100

Hence, I took bike for 100 miles.

Answer:

The vehicle can travel 12 miles per gallon of gasoline

Step-by-step explanation:

Proportions

A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles.

It's required to find the rate of miles per gallon of gasoline consumption of the vehicle.

First, we convert all the mixed fractions to improper fractions:

[tex]1\frac{1}{8}=1+\frac{1}{8}=\frac{9}{8}[/tex]

[tex]13\frac{1}{2}=13+\frac{1}{2}=\frac{27}{2}[/tex]

The rate of consumption is:

[tex]\displaystyle \frac{\frac{27}{2}}{\frac{9}{8}}[/tex]

Operating:

[tex]\displaystyle \frac{\frac{27}{2}}{\frac{9}{8}}=\frac{27}{2}\cdot\frac{8}{9}=12[/tex]

The vehicle can travel 12 miles per gallon of gasoline

The petting zoo at the park has 61 ducks and sheep, combined. The animals have a total of 150 legs. How many sheep are there

Answers

Answer:

7

Step-by-step explanation:

The number of sheep in the petting zoo will be 7.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the petting zoo at the park has 61 ducks and sheep, combined. The animals have a total of 150 legs.

The number of sheep will be calculated by forming the linear equation for the total number of legs,

61 x 2 + 4s = 150

4s = 150 - 122

4s = 28

s = 7

The number of sheep will be 7.
