Paolo is solving the inequality 15+2x>31.
To solve the inequality, he begins by solving the equation as shown.
Which number line represents the solution to the inequality?
Answers
Answer:
The number line that shows x > 8
Step-by-step explanation:
First, subtract 15 from both sides
15 + 2x -15 > 31
2x > 16
Then divide both sides by 2
2x ÷ 2 > 16 ÷ 2
x > 8
The answer is:
x > 8
Work/explanation:
To solve this inequality, we need to isolate x.
So first, I subtract 15 on each side:
[tex]\sf{2x > 31-15}[/tex]
[tex]\sf{2x > 16}[/tex]
Now, divide each side by 2:
[tex]\sf{x > 8}[/tex]
Hence, the answer is x > 8.A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 9 hours? What is the rate of speed of the jet?
Answers
Answer:
235 miles per hour and 2,115 miles in 9 hours
Step-by-step explanation:
First determine how many miles the jet files in one hour:
470/2 =235 miles/hour
We want to know how many hours the jet could fly in 9 hours, so we multiply this value by 9.
235 x 9 = 2115 miles
Therefore, the jet could fly 2115 miles in 9 hours.

A race car game takes 6 points from a player each time the player hits a cone. What integer represents the change in total points if the player hits 10 cones?
Answers
Given:
A race car game takes 6 points from a player each time the player hits a cone.
To find:
The integer which represents the change in total points if the player hits 10 cones.
Solution:
According to the given information,
1 hit = -6 points
Here, negative sign represents the reduction in points after hitting a cone.
If the player hits 10 cones.
(1 × 10) hit = (-6 × 10) points
10 hit = -60 points
So, the change in total points if the player hits 10 cones is -60.
Therefore, the required integer is -60.
Answer: 60
Step-by-step explanation:
based on the given conditions, formulate:

The slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the equation of the line as 5x - 2y = 20.
We have the equation of the line as -
5x - 2y = 20
2y = 5x - 20
y = (5/2)x - 10
[m] = 5/2
Therefore, the slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

In a cafeteria 1/10 of the students are eating salads, and, 2/5 are eating sandwiches. there are 20 students in the cafeteria. how many students are eating lunches other than salads or sandwiches
Answers
20 x 1/10 have salads = 2 students
and
20 x 2/5 have sandwiches = 8 students
so 10 students are eating lunches other than salads or sandwiches
(20 - 2 - 8)
or 1/10 + 2/5 = 1/10 + 4/10 = 5/10 have salad and sandwich
so 5/10 have no salad no sandwich
and 5/10 x 20 = 10
Answer:
5/10, or 1/2
Step-by-step explanation:
2/5 = 4/10
4/10 + 1/10 = 5/10

Answers
Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.
What is bankruptcy?Bankruptcy is a legal proceeding involving a person or business that is unable to repay its outstanding debts.
Had Lewis not filed bankruptcy, he would have paid = 90+50+65+75
He would have paid (let us say amount A)= $280
After filing for bankruptcy he has to pay = 205+75+150+110
He has to pay (let us say amount B)= $540
Difference between amount A and amount B = $540-$280
Difference between amount A and amount B = $260
Therefore, Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

The gas mileage of two trucks was compared from two different advertisements. The information is shown in the table.

BTruck A, because for every gallon the truck goes 19 miles. CTruck B, because for every mile the truck uses 18 gallons. DTruck B, because for every gallon the truck goes 18 miles
Answers
The gas mileage of the trucks is the number of miles traveled per gallon of gas
The truck that has the best gas mileage is (b) Truck A, because for every gallon the truck goes 19 miles.
How to determine the true statementAs stated above, gas mileage measures the miles traveled by one gallon of gas.
This means that options (a) and (c) cannot be true, because these options measure the number of gallons used per mile
From the complete question, truck A uses 1 gallon for 19 miles, while truck B uses 1 gallon for 18 miles.
19 miles per gallon is greater than 19 miles per gallon
This means that truck A has the greater mileage
Hence, option (B) is true

Your job is to decide whether their work is right or wrong. If you see an equation that is false, then: Say it is False. Then how you know it is false. 2(n + 3) = 2n + 3 *
Answers
Answer/Step-by-step explanation:
Given that a student wrote the following equation:
[tex] 2(n + 3) = 2n + 3 [/tex]
Looking at the expression on both sides, they don't seem equal. To be sure, use any value to represent "n" in the equation. Then, simply. If what you have on your left is equal to what you have in your right, then the equation is TRUE. If otherwise, it is FALSE.
Let n = 2
[tex] 2(n + 3) = 2n + 3 [/tex]
[tex] 2n + 6 = 2n + 3 [/tex]
Plug in the value of n
[tex] 2(2) + 6 = 2(2) + 3 [/tex]
[tex] 4 + 6 = 4 + 3 [/tex]
[tex] 10 = 7 [/tex]
This is not FALSE. 10 ≠ 7.
Therefore, the equation written by the student is FALSE.
