N+2=-14-n 46 POINTS WORK SHOWN
Answer:
woah that seems too complicated for my 9th grade brain
Step-by-step explanation:
n+2=−14−n
Move all terms containing n to the left side of the equation.
2n+2=−14
Move all terms not containing n to the right side of the equation.
2n=−16
Divide each term by 2 and simplify.
So the answer is: n=−8

g The company charges a flat fee of $20 plus $0.48 for every mile the car is driven. Find the cost c c of renting a car from Rent-A-Wreck for a day when x x number of miles are driven.
Answer:
The cost for day when x miles are driven is
C = 0.48x + 20
Step-by-step explanation:
Firstly, we shall need to write an equation that represents the rent age
Let C be the cost and m is the number of miles driven
C = 20 + 0.48m
So given that x miles are driven, then m = x
This implies = 20 + 0.48x

find the slope and y- of the table
Answer:
y = (3/2) x +6
Step-by-step explanation:
The y-intercept is clearly at y = 6 point (0, 6) of the table.
The slope can be calculated using any two pairs, for example (-4,0) and (-2, 3)
slope = (y2 - y1)/(x2 - x1) = (3 - 0) / (-2 + 4 ) = 3/2
Then the equations of the line in slope y-intercept form is:
y = (3/2) x +6

A popular restaurant advertises that it delivers its orders within 30 minutes. Suppose the average delivery time for one store is 27 minutes with a standard deviation of three minutes. One particular order delivery has a z-score of –2.15. Which of the following statements is not a correct interpretation?
A.The delivery time was 2.15 standard deviations below the average delivery time.
B.The delivery time was less than the average delivery time by 2.15 standard deviations.
C.The delivery time was faster than the average delivery time by 2.15 standard deviations.
D.The delivery time was slower than the average delivery time by 2.15 standard deviations.
Answer: B. The delivery time was less than the average delivery time by 2.15 standard deviations.
Step-by-step explanation:
Given: A popular restaurant advertises that it delivers its orders within 30 minutes.
Suppose the average delivery time for one store is 27 minutes with a standard deviation of 3 minutes.
z-score value represents the number of standard deviations is the data value is far from mean.
Here, z-score = -2.15 which clearly indicates that the delivery time was 2.15 standard deviations below( '-' sign suggest value is below mean) the average delivery time.
Hence, the correct option is B.

FIRST RIGHT GETS BRAINLIEST. Find the decimal and Percent of 2/3
Answer:
0.667 and 66.67% rounded
Step-by-step explanation:
2/3 = 0.66666 repeating which can be rounded to 0.667
2/3 = 66.6666% repeatinf which can be rounded to 66.67%
_
Answer: Decimal = 0.6 Percent = 66.67%
Step-by-step explanation: The line above the 6 in 0.6 stands that it repeats over and over again, and the percent is 66.67% because if you divide 100/3x2, you get 66.67.

A 40 -inch board is to be cut into three pieces so that the second piece is 4 as long as the first piece and the third piece is 5 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.
Answer:
4*4=16 INCHES FOR THE SECOND PIECE. 5*4=20 INCHES FOR THE LONGEST PIECE.
Step-by-step explanation:
x = 20 inch, the length of the first piece
What is mathematical expression?
A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
given,
Total length = 40 inch
let first piece be = x inch
second piece = 4 times of first piece = 4x inch
third piece = 5 times of first piece = 5x inch
So,
x + 4x + 5x = 200
10x = 200
x = 200/10
x = 20
Therefore, the length of the first piece is 20 inch

what is 3/7 × 3 3/7?
= 3/4 × 3 3/7
= 3 3/7 as an improper fraction = 24/7
= 3/4 × 24/7
= 3 × 24 / 4 × 7
= 72/28
Let us try to simplify it .
We know that both 72 and 28 is divisible by 4 . Hence ,
72 ÷ 4 / 28 ÷ 4
= 18/7
Therefore , 3/7 × 3 3/7 = 72/78 or 18/7 ( simplest form ) .
