Answer:
He would be done by 10:30
Step-by-step explanation:
If you have 6:30 and you add 4 hours to it you end up with 10:30 because, forget the '30' for a second and take 6:00. You go 6 to 7 = 1 hour. 7 to 8 = 2 hours. 8 to 9 = 3 hours. 9 to 10 equals 4 hours. Which is what we are trying to get to. So you take that 10 and add the '30 back to it and you get 10:30.
Hope this helps you :)

Solve for x: x − 2 > 2x + 12. (1 point) x > 14 x < 14 x > −14 x < −14
Answer:
Step-by-step explanation:
x<-14
Answer:
x < -14 is correct.
Step-by-step explanation:
Here is the work:
x - 2 > 2x + 12
I will start by getting rid of the 2x , so subtract 2x from both sides.
-x -2 > 12
Add 2 to both sides.
-x > 14.
Multiply by negative 1 on both sides because -1 times -1 is 1, so you get 1x (x).
When multiplying by a negative, you switch the sign around.
x < -14.
Example 5: Taro and Jiro climbed a mountain and hiked back down. At the suminit and at every station along the way back down, they recorded their altitude and the amount of time they had been travelling. Hiking Data Time Traveled (in minutes) Altitude (in meters) 0 3776 3600 29 3 Å 126 3020 2700 179 3 231 2390 Construct a linear function to model the relationship between Taro's and Jiro's altitude in terms of the amount of time they traveled.
Answer:
i
Step-by-step explanation:
ask your teacher
Answer:
Let the altitude be represented by y and the time taken by x
so y = 3776 - 6x
What is a Linear Function?A linear function is an algebraic equation with variables with a degree of only 1 and constants and is represented in a straight line form on a graph.
What is Slope?The slope Of a straight line (which represents a linear function) is the tangent of the angle made by the line with the x-axis. For a straight line passing through (x1,y1) and (x2,y2) the slope is given by
m= (y2-y1)/(x2-x1).
How to write an equation of a Straight line?y-y1 = m(x-x1) where y represents y co-ordinate and x represents x- co-ordinate and m is the slope of the line which passes through(x1,y1).
Solving the question with the Above conceptsSo let time in minutes be represented by 'x'
So let altitude in meters be represented by 'y'
So the (x,y) coordinates according to the given data are (0,3776),(88/3,3600),(126,3020),(538/3,2700) and (231,2390).
So for slope which is m = (3600-3776)/(88/3-0) so slope = -6.
So the linear function is: y-3776 = -6(x-0)
6x+y=3776
So the linear function for the altitude in terms of the time they traveled is 6x+y = 3776

A friend gave Ms. Morris a gift card for a local car wash. The table shows the linear relationship of how the value left on the card relates to the number of car washes.
Number of car washes, x 0 8 12
Amount left on card ($), y 70 50 40
Part 1 out of 3
Enter an equation that shows the number of dollars left on the card.
The equation that represents this situation is y =
Answer:
Step-by-step explanation:
The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
a. Write an equation that shows the amount of dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
The equation is y = -3/2x + 30
b. Explain the meaning of the negative slope above.
As the number of car washes increase, the dollars left on the card decreases.
c. What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2
x = 20
A restaurant needs to plan seating for a party

[2−∣∣−14−2(−35)∣∣]÷(−6)
What is the value of the expression?
Enter your answer as a simplified fraction in the box.
Answer: its - 7/40
Step-by-step explanation: i took the test
The value of the expression after simplifying the given expression [2−∣∣−14−2(−35)∣∣] ÷ (−6) is 0.141
What is Expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. For example -
5x + 7 = 6
7r + π = 4
Given is the following expression -
[2 - | - 1/4 - 2 - 3/5|] ÷ (-6)
Assume that -
[A] = 2 - | - 1/4 - 2 - 3/5|
[B] = - 6
First, we will simplify [A] as follows -
2 - | - 1/4 - 2 - 3/5|
2 - | - 2.25 - 3/5|
2 - | - 2.25 - 0.6|
2 - | - 2.85|
2 - 2.85
- 0.85
We got -
[A] = - 0.85
Now, we can easily find the value of -
[A] ÷ [B] = (- 0.85)/(- 6)
[A] ÷ [B] = 0.85/6
[A] ÷ [B] = 0.141
Therefore, the value of the expression after simplifying the given expression [2−∣∣−14−2(−35)∣∣] ÷ (−6) is 0.141

Based on the information given the amount that each elevator cost them is $2,000.
Using this formula
Cost=Sales price/(1+Percentage profit)
Where:
Sales price=$2,500
Percentage profit=25%
Let plug in the formula
Cost=$2,500/(1+.25)
Cost=$2,500/1.25
Cost=$2,000
Inconclusion the amount that each elevator cost them is $2,000.
