both of the costs will = each other so you make an equation where they are equal and x= 18 so just plug that in for the number of pages. and you get 93=93
|2s-7| is bigger than or equal to -1
The inequality expression of the statement is |2s - 7| >= -1
What are inequality expressions?Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
How to represent the statement as an expression?The mathematical statement is given as
|2s - 7| is bigger than or equal to -1
The term "bigger than or equal" means greater than or equal to
In mathematics, the term greater than or equal to is represented as >=
So, we have the representation of the mathematical statement to be
|2s - 7| >= -1
From the question, we are not instructed to simplify the expression
This means that we leave the expression |2s - 7| >= -1 unsimplified
Hence, the mathematical statement as an expression is |2s - 7| >= -1

(b) They spent $130 to rent a bounce house for 8 hours. How much is the hourly rate for the rental? Show your work. (c) If the parents spent a total of $182.53 on the party, how much more did they spend than what was spent in parts (a) and (b)? Show your work.
Answer:
Step-by-step explanation:
(a) 2.49 * 6 = 14.94 <== what they spent on goodie bags
(b) 150 for 8 hrs = 150/8 = 18.75 per hr

Answer:
The last option: x > -2 and x < 5
Step-by-step explanation:
First of all we look at the circles at the end.
Both are open circles, which indicates that -2 and 5 are not included.
Reading left to right, x is greater than -2 (remember, not greater than or equal to)
And x is less than 5 (not including 5)
The compound inequality is x > -2 and x < 5

This past Sunday, the Giants scored 9 points less than twice the Cowboys. The Packers scored 14 more points than the Giants. If the teams scored 81 total points, find the number of points scored by the packers
Answer:
43 points
Step-by-step explanation:
let the score of cowboys is x
and giants make score 9 which is twice less than the cowboys score so
giants score will be = 2x -9
and packers scored 14 more than giants that is (2x - 9) + 14
now sum of their scores is equal to 81 it means:
x + (2x - 9) + (2x -9) + 14 = 81
x + 2x - 9 + 2x - 9 + 14 = 81
5x = 81 + 4
5x = 85
x = 17
packers scored = (2x - 9) + 14
= 2 (17) -9 + 14
=38 + 5 = 43 points

help please this is timed i’m not sure if my answer is correct
(it’s abt perpendicular, parallel and skew lines)
Answer:
Perpendicular
Step-by-step explanation:
Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).
Answer:
It would be perpendicular.
Step-by-step explanation:
Perpendicular lines form a 90-degree angle.
Skew lines are on different planes and do not intersect.
Since A and D intersect with a 90-degree angle they're perpendicular.

1st Q: C. Algebraic Expression; it consists of numbers and a variable.
2nd Q: D. The number of times Chris washes the car.
Step-by-step explanation:
1st Question:
Numerical Expression: Contains numbers and operations. Numerical expressions are your typical 2 + 2 equations. The ones you start learning in Kindergarten with just numbers and different operations such as addition, subtraction, division, and multiplication.
EX: 108 - 24 = ?
? = 84
Algebraic Expression: Contains numbers, operations, and variables. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.
EX: 2x + 3 = 7
x = 2
__________________________________
2nd Question:
Amount Chris earns per wash: $10.00
# of times Chris washes the car: x
So 10x means what...?
10 = earns per wash
x = times washed the car
Multiply 10 by x to find the total Chris earns for the number of times he washes the car, x.
(Just as a reference, this would be counted as an Algebraic Expression).
Hope this helps! :)

Drag and drop the equation to correctly complete the sentence.
The equation of the line that passes through the points (2, -7) and (5, -1) is
????
Answer:
y= 2x - 11
Step-by-step explanation:
(-7 +1 )/ (2-5) = 2
y= 2x +b
-1 = 2* 5 + b
solve for b and you get -11 so the equation of the line is :
y = 2x -11
What are the x and y-intercepts of the line described by the equation?

Question 2 options:
x-intercept = -6.2
y-intercept = -3.1
x-intercept = -3.1
y-intercept = -6.2
x-intercept = 6.2
y-intercept = 3.1
x-intercept = 3.1
y-intercept = 6.2
Please help
Answer:
x-intercept = 6.2 , y-intercept = 3.1
Step-by-step explanation:
First turn 2x + 4y = 12.4 to slope-intercept form (y = mx + b) where m is slope and b is y-intercept.
Subtract 2x on both sides to move it to the other side, and get 4y by its self. Now it looks like 4y = -2x + 12.4 (since 2x and 12.4 aren't like terms, you wouldn't combine them).
Next, divide 4 on both side to get rid of it, and to get y by its self. Now you'll have
y = -2/4 x + 3.1 (since 12.4 can be divided by 4, that's how you get 3.1). You can already tell, just by looking at
y = -2/4 x + 3.1 , that the y-intercept is 3.1
Now we graph, to find out what the x-intercept is. I did it for you above.⤴⤴⤴

In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
a = 3
a = 8
a = 18
a = 33
Answer:
18
Step-by-step explanation:
if it adds 5 then 13+5=18
Answer:
a = 18
Step-by-step explanation:
We know from the table that our function must be y = 5x -2. We get this information by plugging in 13 = 5(3) - b and solving for b. Now that we have our function we plug in 4.
y = 5(4) -2
y = 20 - 2
y = 18
A painter earns $15 per hour. What is the minimum number of hours he must work to earn at least $200? Write an inequality to represent this situation and solve. Show your work.
PLEASE DO STEP BY STEP BECAUSE IT NEEDS ME TO SHOW MY WORK!
BEST ANSWER GETS BRAINLIEST! :) TYSM I NEED ANSWER ASAP
Answer:
200<=15x
divide by 15
You have to work at least 13 1/3 hours to earn $200
<= means greater than or equal to
Step-by-step explanation:
The minimum number of hours to earn at least $200 is 14
How to determine the minimum number of hours?Let the number of hours be x.
Given that hourly rate is $15, and he needs to earn at least $200;
The inequality of the scenario is:
15x >= 200
Divide both sides by 200
x >= 13.33
The smallest integer greater than 13.33 is 14.
So, we have:
x = 14
Hence, the minimum number of hours is 14

The area of a curved surface of a cylinder is 4400cm² and the circumference of its base 110cm. Find the height of the cylinder.
Step-by-step explanation:
Area of a curved surface of a cylinder = 4400 cm².
The circumference of its base = 110 cm.
As we know that,
Formula of : circumference of base = 2πr.
→ 2πr = 110.
→ πr = 55.
Formula of : Curved surface area of cylinder = 2πrh.
→ 2πrh = 4400.
Put the value of πr = 55 in the equation, we get.
→ 2(55)h = 4400.
→ 110h = 4400.
→ h = 40 cm.
Height of cylinder = 40 cm.
let the graph of g be horizontal shrink by the factor of 2/3 followed by a translation 5 units left and 2 units down of the graph of f (x) =x ^ 2
1. horizontal shrink by factor of 2/3 means multiply outside the f(x) or outside the x^2 by 2/3:
(2/3)•f(x)
2. translation left 5 units means "x+5" inside:
(2/3) • f(x+5)
3. tranlate down 2 units means "-2" outside:
(2/3) • f(x+5) -2
