Answer: x = 8
Step-by-step explanation:
9 ( x - 3 ) = 45
distribute 9
9x - 27 = 45
combine constants
9x = 45 + 27
compute 45 + 27
9x = 72
divide both by 9
9x/9 = 72/9
final answer
x = 8
Find the solutions for 32(x² + 4x)=16(x² + 4x + 3)
.
Answer:
Simplify 32(x^2+4x)
32x^2+128x=16(x^2+4x+3)
simplify 16(x^2+4x+3)
32x^2+128x=16x^2+64x+48
subtract 16x^2 from both sides
subtract 64x from both sides
subtract 16x^2 and 32x^2
subtract 64x from 128x
x=−2+√7,−2−√7 answer
hope this helps :))
Choose the correct scale facto:
2
3
1/2
1/3
Given:
The graph of a figure and its image after dilation.
To find:
The scale factor.
Solution:
From the given graph it is clear that
ND = 3 units
N'D' = 6 units.
We know that,
[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of original figure}}[/tex]
[tex]\text{Scale factor}=\dfrac{N'D'}{ND}[/tex]
[tex]\text{Scale factor}=\dfrac{6}{3}[/tex]
[tex]\text{Scale factor}=2[/tex]
Therefore, the scale factor is 2 and the correct option is A.

Answer:
1/18
Step-by-step explanation:
Answer:
1/18
Step-by-step explanation:
When dividing a fraction with another number or fraction you always do the reciprocal of the second number and it turns into multiplication.
so it'll look like this: [tex]\frac{1}{9} *\frac{1}{2}[/tex]
then you just multiply straight across to get 1/18 because 1*1 is still 1 and 9*2 is 18

Answer: 4x + 2y
Step-by-step explanation: 1/2(6x-8y) = 3x - 4y
1/2 * 6x= 3x
1/2 * 8y = 4y
-3(x - 2y) = -3x + 6y
-3 * -2 = 6y
4x - 3x + 6y + 3x - 4y
= 4x + 2y

First, we need to figure out how much you want to borrow. You said you wanted to spend $5,000, and you will put $500 down. Based on that, we can estimate your taxes to be $340. Put those numbers into the calculator and press calculate to see how much money you will need for your loan.
can anyone tell me the answer pls
You need $4840 money for the loan.
What is addition?Through addition, objects are combined and counted as a single large group. The process of adding two or more numbers together is known as addition in mathematics. The terms "addends" and "sum" refer to the numbers that are added and the result of the operation, respectively.
According to the question,
Spending amount =$5000
Down payment = $500
Taxes amount = $340
The total loan amount :
= Spending amount - down payment + Taxes amount
By substituting the above values, we get
= $5000 - $500 + $340
= $4840
Therefore, the loan amount is $4840.

Swim flippers are helpful for scuba
diving. You can rent them daily for
$15 per day, plus 8% tax. How
much will it cost, including tax, to
rent them for three days?
Answer:
The answer would be $48.60.
Step-by-step explanation:
Some people could probably answer it better but here's my way: When you have a percentage of something you bring it to the decimal. 8% would be 0.08. We take this and multiply it by the cost: 0.08 times 15, giving us $1.2 per $15 dollars spent. 1.2 times the 3 days would be 3.6 and 15 times 3 is 45 together this would give you the grand total of $48.60.

What graph represents a function?
Answer:
Bottom answer
Step-by-step explanation:
Although I cannot see the answer labels, the answer is the very bottom graph. The way you can find a functional graph is if you add vertical lines going down and that there is only one point that crosses it, not two. It is kind of difficult for me to explain, so if you need help, I suggest you look up how to know when a graph is a function or not.

5 positive integers are arranged in ascending order, as follows:
7, 8, 11, 11, X
The median and the range are equal.
Find 2.
Answer:
X = 18.
Step-by-step explanation:
The median = 11 so the mean is also 11 (given).
So mean = 11 = (7 + 8 + 11 + 11 + X) / 5
(37 + x)/ 5 = 11
x + 37 = 55
x = 55 - 37 = 18.
A furniture company sells a desk for $1,435. It cost the company $817 to make the desk. Last month, 253 desks were sold. What is the total profit earned by the company from the desk last month?
Answer:
Net profit= $156,354
Step-by-step explanation:
Giving the following information:
A furniture company sells a desk for $1,435. It cost the company $817 to make the desk. Last month, 253 desks were sold.
To calculate the net profit, we need to use the following formula:
Net profit= number of units sold*(selling price - unitary cost)
Net profit= 253*(1,435 - 817)
Net profit= $156,354

69.08 cmExplanation :Given :Radius of a circle = 11 cmTo Find : Circumference of the circle = ?Solution :As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :
[tex] \large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]
By filling value of r = 11 cm and π = 3.14, we have :
[tex] \sf : \implies Circumference = 2 \times 3.14 \times 11 \: cm[/tex]
[tex] \sf : \implies Circumference = 2 \times \dfrac{314}{100} \times 11 \: cm[/tex]
[tex] \sf : \implies Circumference = \dfrac{628}{100} \times 11 \: cm[/tex]
[tex] \sf : \implies Circumference = \dfrac{6908}{100} \: cm[/tex]
[tex] \sf : \implies Circumference = 69.08\: cm[/tex]
Hence, circumference of the circle is 69.08 cm.
The master roofer wants to put the ladder on the side of the house but she doesn't
know if it can be set at the proper angle. What will be the angle of elevation if the
10-foot long ladder is placed 1 feet from the wall?
Answer: About 84.261 degrees
Step-by-step explanation:
To find the angle of elevation, we can create a triangle and solve for the angle.
First, we can imagine a triangle with side A being the ground between the base of the ladder and the wall, side B being the wall (from the base of the wall to where it touches the top of the ladder), and side C being the ladder (from where it touches the ground to where it touches the wall).
In the problem, it has already given us two of the side lengths we need to solve for the angle of elevation:
1. We know that the ladder is 10 feet tall, so we can say that side C is 10.
2. We know that the ladder base is placed 1 foot from the wall, so we can say that side A is 1.
The angle of elevation is the angle that the ladder is tilted from the ground, or the angle between the ground (side A) and the ladder (side C). These sides relative to the angle would be the adjacent (side A) and the hypotenuse (side C).
To calculate for the angle, we can use the cosine function. (cos = adjacent / hypotenuse)
To find the angle of elevation (which we can call angle b), we can use:
cos(b) = A / C
arccos(A / C) = b
(Note: arccos is the inverse of the cos function)
Then, we can plug in the values and get:
b = arccos(1 / 10)
b = 1.471 radians OR 84.261 degrees

In triangle QRS, the measure of angle RSQ is 29.1*, and the measure of angle
QRS is 76*. What is the measure of angle SQR?*
Answer:
74.9 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. Add 29.1 and 76 to get 105.1, and then you can subtract that from 180 to get 74.9.

Find the solution to this system of equations and write it as an ordered
pair (x, y) *
3x + 3y = -18
2x - 4y= -6
Answer:
Step-by-step explanation:
Simplifying
3x + 3y = -18
Solving
3x + 3y = -18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
3x + 3y + -3y = -18 + -3y
Combine like terms: 3y + -3y = 0
3x + 0 = -18 + -3y
3x = -18 + -3y
Divide each side by '3'.
x = -6 + -1y
Simplifying
x = -6 + -1y
//////////////
Simplifying
2x + -4y = -6
Solving
2x + -4y = -6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
2x + -4y + 4y = -6 + 4y
Combine like terms: -4y + 4y = 0
2x + 0 = -6 + 4y
2x = -6 + 4y
Divide each side by '2'.
x = -3 + 2y
Simplifying
x = -3 + 2y
23 divided by negative 3
If you would like to make $586 in 6 years, how much would you have to deposit in an account that pays simple interest of 3%?
Round all answers to 2 decimal places.
Answer:
$3255.56
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
P = 586 / ( 0.03 × 6 ) = 3255.5555555556
P = $ 3,255.56
The principal required to
accumulate interest of $ 586.00
on a rate of 3% per year for 6 years is $ 3,255.56.
