or
x = s /3 − 2 r/ 3
Step-by-step explanation:
Answer:
2r+3x=5
2r+3x+-3=5+-3x
2r=5-3x
2r/2=5-3x
2r/2=5-3x/2

To rent a taxi in Los Angeles, the taxi service charges a flat rate of $11.20 and an additional $3.10 per mile driven. Write an equation in slope- intercept form where x represents the distance of the trip, and y represents the amount the taxi service would charge to drive that distance .
Answer:
y = 3.1x + 11.2Step-by-step explanation:
Flat rate is the y- intercept b = 11.2
Charge per mile is the slope m = 3.1
The equation is:
y = 3.1x + 11.2Solve for the given variable.
3s - 17 = 19
Add 17 to both sides-
3s - 17 = 19
+17 +17
Now, divide both sides by 3-
3s/3 = 36/3
Which gives the answer of s = 12

The volume of this sphere is 972 pi cubic inches. What is its radius?
A sphere.
Recall the formula Sphere Volume = four-thirds pi r cubed.
7 inches
9 inches
108 inches
324 inches
volume of a sphere = ⁴/₃ πr³
⇒ 972π in³ = ⁴/₃ πr³
729 in³ = r³
r = 9 in
∴ the radius of a sphere of volume 972π in³ is 9 inches.Answer:
9 inches

a deposit of $2000 is invested in an account that earns 4.5% interest. how long until your balance reaches $3000? (assume simple interest) A= P(1+r)^t
A deposit of $2000 is invested in an account that earns 4.5% interest. The duration of time before the balance reaches $3000 is 9.2 years.
From the given information;
the principal deposited amount = 2000the annual interest rate = 4.5%the amount (A) estimated in t years = 3000The time required until your balance reaches the amount of 3000 can be estimated by using the given formula;
[tex]\mathbf{A = P ( 1+ r)^t}[/tex]
[tex]\mathbf{3000 = 2000 ( 1+ \dfrac{4.5}{100})^t}[/tex]
[tex]\mathbf{3000 = 2000 ( 1+ 0.045)^t}[/tex]
[tex]\mathbf{3000 = 2000 ( 1.045)^t}[/tex]
[tex]\mathbf{3 = 2( 1.045)^t}[/tex]
[tex]\mathbf{( 1.045)^t= \dfrac{3}{2}}[/tex]
[tex]\mathbf{( 1.045)^t= 1.5}[/tex]
[tex]\mathbf{( 1.045)^t= 1.5}[/tex]
t = 9.2 years
Therefore, we can conclude that the time duration (in years) until your balance reaches $3000 is 9.2.

Dad spends a total of $1,380 on car insurance for 6 months. What is the average cost per month?
Answer:
$230
Step-by-step explanation:
what is the average hourly pay of someone making $45,000per year. Assuming wage growth of 5% a year, how much would he make the second year
Answer:
When it’s time for annual performance reviews, if you plan on including pay raises, you need to know the simple math behind calculating pay increases correctly. Raises can be based on any number of things including a worker’s piers, standard industry rates, length of time on the job, the amount of work to do, and even whether or not the boss likes the employee or not. There are few, if any, laws that govern how and when increases are granted, so it’s up to you to determine what you’re willing to give.
Answer:
See belowStep-by-step explanation:
Assume the person works 40 hours a week and 52 weeks a year.
The hourly pay would be:
$45000 ÷ (40*52) = $45000 ÷ 2080 =$21.63The yearly income the second year:
$45000 + 5% = $45000*1.05 = $47250PLS ANSWER You start a savings account with $200 and save $30 each month. Write a rule to represent the amount of money you invest into your savings account as an arithmetic sequence. How much money will you have invested after 12 months?

Question 20 of 40
Anna thinks of a number. She subtracts 5 from the number, multiplies the
result by 2, and then adds 6. The number she ends up with is 14. What
number did Anna start with?
If you work backward to solve this problem, what do you do first?
A. Divide 14 by 2
OB. Add 5 to 14
C. Subtract 5 from 14
D. Subtract 6 from 14
What’s the first steps when doing it backwards ?
Answer:
2(x-5)+6=14 is your starting equation, and then we solve:
2(x-5)+6=14
2(x-5)/2 +6=14/2
x-5+6=7
the first step is to divide by 2, so A :)))

Answer:
x = 41
y = 65
z = 107
Step-by-step explanation:
y and 65 are vertically opposite angles. Vertically opposite angles are equal.
y = 65
74 + y + x = 180
74 + 65 + x = 180
139 + x = 180
x = 180 - 139
x = 41
z is the exterior angle, whereas 66 and x are interior angles in a triangle.
Formula : -
Exterior angle = Sum of two interior angles
z = 66 + x
= 66 + 41
z = 107

How many different 9-letter "words" can you
make by arranging the letters in DEVIATION?
The arrangements don't have to be actual words
that are included in any dictionary.
There are 5040 different 9-letter “words” that can be made by arranging the letters in DEVIATION.
The given word is DEVIATION and we are required to find out the number of different 9-letter “words” that can be formed by arranging its letters.
To solve the problem, we will use the formula for finding permutations of n objects taken r at a time when all the objects are distinct.
The formula is given by: nPr = n! / (n-r)! where n is the total number of objects and r is the number of objects to be selected.
Here, we have 9 objects (letters) and we need to arrange all of them, so r = 9.
Now, we need to find out the value of n.
The given word DEVIATION has 9 letters, but two of them (E and I) are repeated twice.
Therefore, n = 9 - 2 = 7.
We will substitute these values in the formula to get the required answer:
nPr = n! / (n-r)! = 7! / (7-9)! = 7! / (-2)! = 7! / 1 = 5040
Therefore, there are 5040 different 9-letter “words” that can be made by arranging the letters in DEVIATION.

CAN ANYONE PLZ HELP ME WITH THIS WORKSHEET .. I’ll mark as brainliest
Answer:
Step-by-step explanation:
1)
We know that if [tex]x^2=9[/tex], then [tex]x=\pm \sqrt{9}[/tex], so [tex]\boxed{x=3,-3}[/tex]
2)
We know that if [tex]x^3=8[/tex], then [tex]x=\sqrt[3]{8}[/tex], so [tex]\boxed{x=2}[/tex]
3)
[tex]x^3=\frac{1}{8}[/tex] means that [tex]x=\sqrt[3]{\frac{1}{8}}=\frac{\sqrt[3]{1}}{\sqrt[3]{8}}=\frac{1}{2}[/tex].
So, [tex]\boxed{x=\frac{1}{2}}[/tex].
4)
[tex]x^3=27[/tex] means that [tex]x=\sqrt[3]{27}=\sqrt[3]{3^3}=3[/tex].
So, [tex]\boxed{x=3}[/tex].
5)
[tex]x^2=25[/tex] means that [tex]x=\pm \sqrt{25}=\pm \sqrt{5^2}=\pm 5[/tex].
So, [tex]x=5,-5[/tex].
6)
We know that the side length of the square will be [tex]\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}=\boxed{\frac{3}{4}}[/tex].
7)
[tex]6x^2=54[/tex] means that [tex]x^2=9[/tex], which means that [tex]\boxed{x=3,-3}[/tex].
8)
[tex]2x^2+25=75[/tex] means that [tex]2x^2=50[/tex], which means that [tex]x^2=25[/tex], which means that [tex]\boxed{x=5,-5}[/tex]
