Step-by-step explanation:
In the fall, you charge your neighbors $9 for going to their house to rake leaves, then $6 for every
hour you rake. If you make $51 one day, how many hours did you spend raking?
1. Summarize the data given.
You know that you made $51 in just one day. You charge $9 for going to their house, plus $6 hours for raking.
9 + 6x = 51
X = The Hours Spent Raking
2. Turn the equation so then 6x is by itself.
9 + 6x = 51
-9 -9
6x = 42
3. Remove the number, so x remains by itself.
6x = 42
/6 /6
x = 7
So that means, you spent 7 hours raking leaves on the day I made 51 dollars.
Answer:
You spent 7 hours.
Step-by-step explanation:
First add 9 and 6 together which is 15 and then you continue to add 6 until you reach 51. I added 6 to my sum 7 times .

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.
Option A is the correct answer.
We have,
To solve the equation 3x + 7 = 16 - 2x for x, we need to isolate the variable x on one side of the equation.
Let's solve it step by step:
Start with the original equation:
3x + 7 = 16 - 2x
- Add 2x to both sides of the equation to get rid of the -2x on the right side: 3x + 2x + 7 = 16 - 2x + 2x
- Simplifying, we have: 5x + 7 = 16
- Next, subtract 7 from both sides of the equation to isolate the term with x: 5x + 7 - 7 = 16 - 7
- Simplifying, we have: 5x = 9
- Finally, divide both sides of the equation by 5 to solve for x: (5x)/5 = 9/5
- Simplifying, we have: x = 9/5
Therefore,
The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

Points A, B and C are collinear. Point B is between A and C. Find x if AC=20, BC=x-19 and AB=x+17.
Answer:
11
Step-by-step explanation:
20-[(x-19)+(x+17)]
=20-2x+2
=22-2x
As AB+BC=AC, 22-2x=0.
Thus 2x=22

1.)Which has greater density?
object
fluid
neither
2.)The object will
sink
float
be suspended
in the water column.
Answer:
1. Object
2. Sink
Step-by-step explanation:
1.5 < 1, the object is denser than the fluid
When an object is denser than a fluid it is submerged in, the object will sink.

Answer:
-11
Step-by-step explanation:
plug -3 in x values.
h(-3) = -3^2 -2
=-11
Answer: h(-3) = 7
Explanation: If h(x) = x² - 2, then h(-3) = (-3)² - 2
which simplifies to 9 - 2 or 7.
Remember to always use parenthses when

Given a bottle with a height vs. volume graph that is created as the bottle is consistently filled with liquid, describe the correlation between the width of the bottle and the steepness of the graph?
Answer:
The steepness of the graph will decrease when the width of the bottle is increased.
Step-by-step explanation:
We are told that a bottle with a height vs. volume graph is created asthe bottle is consistently filled with liquid
Now, from initial conditions, the bottle will be empty and immediately we start putting liquid into the bottle, the graph of height vs volume starts.
Now, this height(H) represents the height of the liquid in the bottle while volume(V) is the volume of liquid in the bottle.
Now, we want to find the correlation between the width of the bottle and the steepness of the graph.
Thus, if we are to increase the width of the bottle, it means we are also increasing the capacity of the bottle which is the volume of the bottle.
What this means is that for us to get to the same height(H) before the increase in bottle width, we will need to pour in a larger volume of liquid(V').
If the extra amount of liquid to be poured is v, then the new volume that will get the liquid to the initial height(H) is;
V' = V_initial + v
The implication of this is that the slope of the graph will decrease.
Thus in terms of the question, the steepness of the graph will decrease when the width of the bottle is increased.

Write the equation of the line that it is parallel to 5x = 1 - 3y and passes through (9,4).
Answer:
y = -5/3x + 57/3
Step-by-step explanation:
Solve 5x = 1 -3y for y
so 3y = -5x + 1 divided by by 3
y = -5/3x +1/3
Since its parallel it has the same slope
To find the y-intercept you need to move 9 to 0
so the intercept = 12/3 + 45/3 = 57/3

Answer:

Step-by-step explanation:
the cubed root of 216 is 6.
Solve the following system of equations. Express your answer as an ordered pair in the format (a,b), with no spaces between the numbers or symbols.
2x+5y=16
-5x-2y=2
Answer:
[tex]\huge\boxed{(2,4)}[/tex]
Step-by-step explanation:
2x + 5y = 16 ------------------(1)
-5x -2y = 2 ------------------(2)
Multiplying (1) by 5
5(2x+5y) = 16*5
10x+25y = 80 ----------------(3)
Multiplying (2) by 2
2(-5x-2y) = 2*2
-10x - 4y = 4 -----------------(4)
Adding Eq. (3) and (4)
10x + 25y -10x -4y = 80 + 4
25y - 4y = 84
21y = 84
Dividing both sides by 21
y = 4
[tex]\rule[225]{225}{2}[/tex]
Now, Putting y = 4 in Eq. (1)
2x + 5(4) = 16
2x + 20 = 16
2x = 20 - 16
2x = 4
Dividing both sides by 2
x = 2
[tex]\rule[225]{225}{2}[/tex]
Ordered Pair = (x,y) = (a,b) = (2,4)
[tex]\rule[225]{225}{2}[/tex]

Solve the formula for h
The surface area of a cylinder: S= 2πr²
h___
( btw π means pie)
Answer:
[tex]\large \boxed{\sf h= \frac{S-2\pi r}{2\pi r} }[/tex]
Step-by-step explanation:
The surface area of a cylinder:
[tex]S=2\pi r h + 2\pi r[/tex]
Solve for height h
Subtract 2πr from both sides
[tex]S-2\pi r=2\pi r h[/tex]
Divide both sides by 2πr
