Answer: About 14 liters of gasoline is required.

Step-by-step explanation:

On the map,

1 centimeter= 25 kilometers.

Distance the towns along the highway is 4.5 centimeters.

Actual distance = 4.5 x 25 km

= 112.5 km

Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving.

Total gasoline required = 0.123  x  112.5 km

= 13.8375 liters≈ 14 liters

hence, about 14 liters of gasoline is required.

The solution to the equation always not included in the solution to the inequality

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Two or more expressions with an Equal sign is called as Equation.

Where as a relationship between two expressions or values that are not equal to each other is called 'inequality.

Both inequality and equations are different,

Inequalities and equations are both math statements that compare two values.

Equations use the symbol =

Answer:

Step-by-step explanation:

x - smaller number

3x - three times the smaller number = the larger number

2×3x - twice the targer number

2×3x+3x  - twice the larger is added to three times the smaller

2×3x + 3x = 27

6x + 3x = 27

  9x = 27

 ÷9     ÷9

Answer:

$30

Step-by-step explanation:

s + 90 = 120

s = 120 - 90

s = 30

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30

Where s is the amount to spend.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Mirna earned $120 babysitting during spring break.

She needs to save $90 for the German Club trip.

She wants to spend the remainder of the money shopping.

This means,

The remainder amount,

= 120 - 90

= $30

We can write an inequality as,

s ≤ 120 - 90

s ≤ 30

Where s is the amount of money to spend on shopping.

Thus,

The most simplified inequality form of the amount of money s to spend on shopping is

Step-by-step explanation:

12 divided by 4 is 3 and three 3s is 75 percent (I know thats confusing but trust me)

The percentage of shots he make is 75%

The percentage of a number represents a portion or fraction of the whole number expressed as a fraction of 100. It is often used to describe a proportion or rate out of 100.

To calculate the percentage of a number, you typically multiply the number by the desired percentage as a decimal or fraction. The result represents the portion or fraction of the number expressed as a percentage.

The formula for calculating the percentage of a number is:

Percentage = (Number * Percentage Value) / 100.

Substituting the values into the formula above;

percentage = (9 / 12) * 100

percentage = (3/4) * 100

percentage = 0.75 * 100

Percentage = 75%
