Answer:
x = -4
Step 1: Take all the constants on one side and the variables on the other.
(2 × x) + 12 = 4
=> (2 × x) = 4 - 12
(2 × x) = -8
Step 2: Divide 2 both sides to isolate 'x'.
=> [tex]\frac{2x}{2}[/tex] = [tex]\frac{-8}{2}[/tex]
=> x = -4

Three sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister’s age.
Answer:
youngest 17
middle 19
oldest 21
Step-by-step explanation:
Three sisters have ages that are consecutive odd integers
youngest = x
middle = x + 2
oldest = x + 4
--------------------
The sum of the age of the youngest
x
and three times the age of the oldest
+ 3(x + 4)
is five less than five times the middle sister’s age
= 5(x + 2) - 5
-----------------------
x + 3(x + 4) = 5(x + 2) - 5
Distribute
x + 3x + 12 = 5x + 10 - 5
Combine like terms
4x + 12 = 5x - 5
Subtract 4x from both sides
12 = x - 5
Add 5 to both sides
17 = x
youngest x = 17
middle x + 2 = 19
oldest x + 4 = 21
(81)¾ - (27)⅓
\3 × 2³
Answer:
I won't tell you the answer but if you read the solution, you would understand it.
Step-by-step explanation:
81^3/4 is basically 3 times the fourth root of 81. What number multiplies 4 times to make 81? Then multiply that by 3.
Now we have the cube root of 27. If you have a fractional exponent with no numerator, that just means square root, cube root, fourth root.
Eg. the exponent 1/4 would just mean fourth root
Eg. The exponent 1/2 would just mean square root
The cube root of 27 is 3.
The denominator is 3 times 2 to the third power.
PEMDAS
Order of Operations tells us we do exponents first so 2 to the third power is 8 and multiply by that 3.

Your friend tried putting away the sugar for you and cannot get the 14 cups of sugar to fit in the containers! They determined you would need 9 containers to store the 14 cups of sugar.
They show you their calculations:
Answer the following questions.
What mistake did your friend make in calculating the number of containers needed?
*Hint* Look closely at the work shown to find the mistake
How many containers are needed to store the leftover sugar?
Answer:
21 containers
Step-by-step explanation:
When dividing fractions, you can multiply by the inverse of the fraction. For example, in this case, [tex]14 divided by \frac{2}{3} = \frac{14}{1}x\frac{3}{2}[/tex]. Whoever drew the calculations made the mistake of forgetting to flip the second fraction.
The actual solution of the problem is 42/2, or 21/1. 21 containers are needed to store the sugar.

Solve your word problem using a model. Use complete sentences to describe your model, and interpret the quotient in the context of your word problem. If you wish, you may upload a copy of your model.
The model [tex]x = \frac{6}{3}[/tex], can be used to solve the world problem representing a scenario where John wants to share 6 apples amongst his three friends. x = 2, is the quotient which is interpreted as the number of apples each of John's friend will get.
Word problem describes real world situations which can be translated into expressions as a model.
For example, if John has 6 apples and John has three friends, how many apples would each of the friend get (x) if he is to share the 6 apples amongst the three of them?
To solve this, we can model the situation as follows:
Let x represent the number of apples each friend would get (quotient).
Thus:[tex]x = \frac{6}{3}\\\\\mathbf{x = 2}[/tex]
The quotient (x) in this model can be interpreted as the number of apples each of John's friend will get.Thus, the model [tex]x = \frac{6}{3}[/tex], can be used to solve the world problem representing a scenario where John wants to share 6 apples amongst his three friends. x = 2, is the quotient which is interpreted as the number of apples each of John's friend will get.

I WILL GIVE BRAINIEST, PLEASE HELP
Answer:
A = (1, 10)
B = (4,10)
C = (4, 14)
D = (1, 16)
Step-by-step explanation:
Okay, so first, we move, or translate the quadrilateral PQRS down -8 spaces on the graph, turning old points:
P (1, -2) = (1, -10) Q (4, -2) = (4, - 10) S (1, -8) = (1, -16) and R (4, -6) = (4, -14)
Now, we need to rotate this new box into -x, y. So our new points are:
(1, -10) = (-1, 10) (4, -10) = (-4, 10) (1, -16) = (-1, 16) and (4,-14) = (-4, 14)
Now we're reflecting off the y-axis, making our x change. So for our final points:
A(1, 10) B (4,10) D(1, 16) and C(4, 14)
Hope this helps! Please check my math and comment wether this worked or not! :)

Step-by-step explanation:
The width of a rectangular parking lot at the meadowlands is 3/8 mile. If the area is 5/8 square mile, what is the length of the parking lot
let width is x and length is y
x * y = area
=> 3/8 * y = 5/8
=> y = 5/8 ÷ 3/8
=> y = 5/8 * 8/3 = 5/3
the length of the rectangular parking lot is 5/8 mile.

h(x) = (x - 2)^2+3
Which of the following domain restrictions would enable h(x) to have an inverse function?
a. x < 1
b. x ＞5
c. x < 3
d. x > 4
(Ps: all four answer and larger equal then or smaller equal then
Answer:
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Step-by-step explanation:
The graph of h(x) = (x - 2)^2 + 3 is a parabola that opens upward and has vertex at (2, 3). If the entire graph is drawn, and the horizontal line test then applied, h(x) would not have an inverse, because the horizontal line would intersect the parabolic graph twice.
Note that if we restricted the domain to x ≥ 2, the resulting graph would pass the horizontal line test. This would also be true for x ≥ 3, x ≥ 4, and so on. Not so for (a) x < 1. False for x > -5. True for x < 3. True for x > 4.
No inverse function: (a), (b), (c)
Inverse function exists: (d)

What is the equation of a line that is perpendicular to the line y=2x+1 and passes through the point (4,6)?
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (4, 6 ) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = - [tex]\frac{1}{2}[/tex] x + 8 ← equation of line

what is the answer, i tried everything but i can’t seem to get the right answer
Answer:A
Step-by-step explanation: It never talks about 50 so i don't know why that is there so I think it is A because 21 dollars is more than 5+2.75, (not 100% sure but at least 85% sure)
Answer:
A
Step-by-step explanation:
The reason that this is A is because 5$ is the initial fee and you dont pay any more than that, since 21$ is the max you can afford it is going to be less than or equal to 21. and if it is 2.75$ per stop then it is the number of stops times 2.75. A is your answer.
edit: and the 50 kilometers doesnt have any value in the situation so basically it was just there to confuse you or throw you off.

let the number be n , then
78 - [tex]\frac{1}{2}[/tex] n = 45 ( subtract 78 from both sides )
- [tex]\frac{1}{2}[/tex] n = - 33 ( multiply both sides by - 2 to clear the fraction )

Colleen buys a robot priced at $33.If the sales tax is10%,how much tax will Colleen pay?
Answer:
$3.3 tax
Final price is 36.3
Step-by-step explanation:
Firstly, if the tax is expressed in percent, divide the tax rate by 100. You can do this by simply moving the decimal point two spaces to the left. In this example, we do 10/100 = 0.1
tax= 33 * 0.1
tax=3.3
Finally, add tax to the before tax price to get the final price including tax.
The final price including tax = 33 + 3.3 = 36.3
