Suppose that a desk and a chair together weigh at most 55 pounds. The weight of the chair is 17 pounds. Which inequality correctly describes these conditions for the weigh of the desk, d?

Answer:

x-y=5

4x+6y=120

Step-by-step explanation:

let x = # of 4-point questions

ley y = # of 6-point questions

# of 4-point questions is 5 more than # of 6-point questions

x=y+5 or x-y=5

now there's the matter of the points. Since each x is worth 4 points and each y is worth 6 points, they total number of points have to add up to 120, therefore:

4x+6y=120

The System of Equation is

x-y=5

4x+6y=120

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let x be number of 4-point questions.

ley y be number of 6-point questions.

as, the 4-point questions is 5 more than 6-point questions

So, x=y+5

or x-y=5.................(1)

Since each x is worth 4 points and each y is worth 6 points, they total number of points is 120.

So, 4x+6y=120....................(2)

Answer:

18:12 (accurate)

3:2 (simplified)

Step-by-step explanation:

The team won 18 games out of 30 total games. Find the amount of games lost by simply subtracting 18 with 30:

30 - 18 = 12

The ratio you are trying to find is won to lost, or won:lost. Plug in the corresponding numbers to the corresponding terms:

won:lost ⇒ 18:12

18:12 is the ratio.

If the teacher asks you to simplify, factor both sides. Divide 6 from both sides:

(18)/6 : (12)/6

3:2

3:2 is your simplified ratio.

Answer:

250 and 2 because i think 250 multiply by 2 is 500

The product of the 500 numbers is 0.

Integers are whole numbers. It is a number without a fraction or decimal component. Integers can either be positive, negative or zero.

Consecutive integers are whole numbers that follow each other on the number line. For example, 1, 2, 3, 4 .... are consecutive integers.

If the sum of the 500 consecutive integers is equal to 250, it means that the consecutive integers would include negative numbers, zero and positive numbers. If the consecutive integers include zero, the product of the consecutive integers would be equal to zero.

Answer:

6.5 hours

Step-by-step explanation:

123-45=78

78/12=6.5

Theo had the limousine reserved for 6.5 hours.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Theo's equation for the cost of renting a limousine is:

c = 45 + 12h

where c is the total cost,

and h is the number of hours reserved.

If the final bill amounts to $123,

we can set c equal to 123 and solve for h:

123 = 45 + 12h

Subtracting 45 from both sides:

78 = 12h

Dividing both sides by 12:

h = 6.5

Therefore, Theo had the limousine reserved for 6.5 hours.

Answer:

23

Step-by-step explanation:

The number of car are in the y-intercept line so just add each one of the for every different bar.

3 + 4 + 5 + 6 + 3 + 2 = 23

So there are 23 vehicles in total.

The number of vehicles are at Nam's Gas Station is 23

Since The number of cars are in the y-intercept line

So here the no of vehicles should be

= 3 + 4 + 5 + 6 + 3 + 2

= 23
