What is the value of x?
11 (9 - 2x) = -(12x + 11)
Answers
Explanation: 99-22x=- 12x - 11
Collect like terms: -22x + 12x = -11 - 99
Divide both sides: -10x = -110 by -10
Answer:
x=11
Step-by-step explanation:
First Distribute 11 to 9 and -2x
Then distribute the negative to 12x and 11
Then calculate like terms
-22x + 12x = -11 -99 which comes out to -10x=-110
Then divide each side by -10
Your answer will then be x=11

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Cable Car is the preferred transportation for 75 residents. Bicycle is the preferred transportation for 30 residents. Together, Streetcar and Bus are the preferred transportation for 25 residents. Together, Bus and Bicycle are the preferred transportation for 54 residents.
Answers
The following conclusions can be drawn from the circle graph:
Cable Car is the preferred transportation for 75 residents. (27% of 300 = 81 residents)
Together, Streetcar and Bus are the preferred transportation for 25% of residents. (15% + 10% = 25% of 300 = 75 residents)
The other two statements are incorrect:
Bicycle is the preferred transportation for 8% of residents, not 30. (8% of 300 = 24 residents)
Together, Bus and Bicycle are the preferred transportation for 18% of residents, not 54. (10% + 8% = 18% of 300 = 54 residents)

Step-by-step explanation:
The shape has no symmetry.
You can easily find this by just imagining how it would look if it was symmetrical from each of those lines.
For B, the bottom half of the shape is not as big as the second half, so it can't be B.
For C, you can see the the shape is more on the right side of the line at the top and more on the left side of the line at the bottom, making it not symmetrical.
It can't be D because C is not symmetrical.
If you were to fold the “object” where any of the given lines are, it would not be symmetrical.

Solve each equation.
Two step equations - integers
Q1. Solve 1 - 7b = -20
Q2. Solve -k - 5 = 0
Q3. Solve -1 + 8a = -129
Answers
Q2: k=-5
Q3 a=-16
The required answers by solving two-step equations are:
Q1. The solution of equation 1 - 7b = -20 is b = 3
Q2. The solution of equation -k - 5 =20 is k = -5
Q3. The solution of equation-1 + 8a = -129 is a = -16
Q1. Solve 1 - 7b = -20
To solve this equation, we will isolate the variable b by performing two steps.
Step 1: Subtract 1 from both sides of the equation:
1 - 1 - 7b = -20 - 1
-7b = -21
Step 2: Divide both sides of the equation by -7 to solve for b:
(-7b) / -7 = (-21) / -7
b = 3
Therefore, the solution to the equation 1 - 7b = -20 is b = 3.
Q2. Solve -k - 5 = 0
To solve this equation, we will isolate the variable k by performing two steps.
Step 1: Add 5 to both sides of the equation:
(-k) - 5 + 5 = 0 + 5
-k = 5
Step 2: Multiply both sides of the equation by -1 to solve for k:
(-k) * (-1) = 5 * (-1)
k = -5
Therefore, the solution to the equation -k - 5 = 0 is k = -5.
Q3. Solve -1 + 8a = -129
To solve this equation, we will isolate the variable a by performing two steps.
Step 1: Add 1 to both sides of the equation:
(-1) + 1 + 8a = -129 + 1
8a = -128
Step 2: Divide both sides of the equation by 8 to solve for a:
(8a) / 8 = (-128) / 8
a = -16
Therefore, the solution to the equation -1 + 8a = -129 is a = -16.
Therefore, the required answers by solving two-step equations are:
Q1. The solution of equation 1 - 7b = -20 is b = 3
Q2. The solution of equation -k - 5 =20 is k = -5
Q3. The solution of equation-1 + 8a = -129 is a = -16

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
Jake received a student loan for $12,000. He plans on paying off the loan in five years. At the end of five years, J. Cole have paid $3600 in interest. What is a simple interest rate on the student loan?
Answers
Answer:
The simple interest rate on the student loan is 6%.
Step-by-step explanation:
To solve for the simple interest rate, use the formula for total simple interest:
\(I = Prt\)
\(I\) = total interest paid
P = principal, or starting value
r = interest rate in decimal form
t = time in years
State known values
P = 12,000
t = 5
\(I\) = 3,600
Substitute known values and isolate "r"
\(I = Prt\)
3,600 = (12,000) (r) (5)
3,600 = (60,000) r
r = 0.06
Since "r" is given as a decimal, convert this to a percentage by multiplying by 100.
0.06 = 6%
∴ The simple interest rate on the student loan is 6%.
Answer=6%
Step-by-step explanation:
Principal(P)=12000
Time(T)=5 yrs
Interest(I)=3600
We have,
I=PTR/100
3600=(12000*5*R)/100
3600*100=60000*R
R=360000/60000
R=6%
