Step-by-step explanation:
x, y are the 2 numbers.
x/y = 9/11
x - y = 6
x = y + 6
now we use that in the first equation
(y + 6)/y = 9/11
y + 6 = 9y/11
11y + 66 = 9y
2y = -66
y = -33
x = y + 6 = -27
but the second equation could also be
y - x = 6
then
x = y - 6
and that in the first equation leads to
(y - 6)/y = 9/11
y - 6 = 9y/11
11y - 66 = 9y
2y = 66
y = 33
x = y - 6 = 27

If 7 giant solar power plants generate 1.3 gigawatts (GW) of energy to power 900,000
homes, how many gigawatts can 21 giant solar plants generate?
(IF YOU PUT RANDOM LETTERS I WILL REPORT PLUS PLEASE DON'T ANSWER THIS AS IT WAS A COLLEGE QUESTION ANSWER LIKE A 5TH GRADE MATH QUESTION WHICH IT IS.)
Answer: 3.9 gigawatts
Step-by-step explanation: 7 x 3 equals 21 so just multiply the 1.3 gigawatts by 3 which would mean 21 giant solar planets generate 3.9 gigawatts.

(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
(c) 182.53 - (150 + 14.94) = 182.53 - 164.94 = 17.59...they spent 17.59

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

First of all we look at the circles at the end.

What are the x and y-intercepts of the line described by the equation?
2x+4y=12.4
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.⤴⤴⤴

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! :)

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.

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 = 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

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.
