It will take 37.3 minutes if they will work together.
What is the time?Time is the seemingly irreversible succession of existence and events that occur from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, compare the duration or intervals between events, and quantify rates of change of quantities in material reality or conscious experience.To find how long it takes the two when they work together:
Let x represent the amount of time it takes them to complete the paper route together.This means that in one minute, they can complete 1/x of the paper route.Candy can complete 1/70th of the route in 1 minute and Tim can complete 1/80th of the route in 1 minute.The part Candy can do in one minute + the part-time can do in one-minute equals the part they can do together in one minute:1/70 + 1/80 = 1/xBecause the LCD has a resolution of 560x, multiply both sides of the equation by 560x:
(560x) · (1/70) + (560x) · (1/80) = (560x) · (1/x)8x + 7x = 56015x = 560x = 560/15 = 37.3 minutes.Therefore, it will take 37.3 minutes if they will work together.

Solve by combining:
-x-y=6
5x-7y=66
Answer:
x = 2
y = 8
Step-by-step explanation:
-x - y = 6
5x - 7y = 66
-x - y = 6
x = -y - 6
5x - 7y = 66
5 ( -y - 6 ) - 7y = 66
-12y - 30 = 66
-12y = 96
y = -8
x = -y - 6
x = 8 - 6

Need help asap
Step-by-step explanation:
Your problem is equivalent to
(x3 - 3x2 + x - 4)/(x-2)
The coefficients of the numerator are 1, -3, 1, -4.
The solution is as follows:
2 | 1 -3 1 -4 Set up the coefficients in decreasing power of x, and 2 is the divisor.
2 -2 -2
------------------
1 -1 -1 -6
Here are the steps:
(a) Bring down the leading coefficient of 1.
(b) 2*1=2. Add -3 and 2 to obtain -1.
(c) 2*-1=-2. Add 1 and -2 to obtain -1.
(d) -1*2=-2. Add -2 and -4 to obtain -6
The quotient has the coefficients 1,-1,-1 so it is x2 - x - 1. The remainder is -6.
Answer :
The result is x2 - x - 1 - 6/(x-2).
You can verify that the answer is correct, because
(x-2)*(x2 - x - 1) - 6 = x3 - 3x2 + x - 4

Use the elimination method to solvethe system of equations. Choose the
correct ordered pair.
-x+y= -2
2x- 3y = 4
Answer: 2(−x+y=−2)
2(−x+y=−2)
1(2x−3y=4)
Becomes:
−2x+2y=−4
2x−3y=4
Add these equations to eliminate x:
−y=0
Then solve−y=0for y:
−y=0
−y/-1 = 0/-1 (Divide both sides by -1)
y=0
Step-by-step explanation:
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+y=−2
Substitute 0 for y in −x+y=−2:
−x+0=−2
−x=−2(Simplify both sides of the equation)
−x/-1 = -2/-2 (Divide both sides by -1)
x=2
Answer:
x=2 and y=0
Answer: x=y+2
Step-by-step explanation:
Step 1: Add -y to both sides.
−x+y+−y=−2+−y
−x=−y−2
Step 2: Divide both sides by -1.
-x/-1 = -y - 2/-1
asnwer: x=y+2
Answer: x = 3/2y + 2
2x−3y=4
Step 1: Add 3y to both sides.
2x−3y+3y=4+3y
2x=3y+4
Step 2: Divide both sides by 2.
2x/2 = 3y + 4/2
answer: x = 3/2y + 2
In montrel was -8 in new york it was 11 deggrees warmer, what was the tempreture in ny?
Answer:
3 degrees
Step-by-step explanation:
-8, -7 -6,-5,-4,-3,-2,-1,0, 1,2 3
If you count 11 spaces to the right on a number line, starting at -8, you will land at 3 degrees.
=========================================================
Explanation:
Think of the +11 as +8+3
Draw a vertical number line. Start at -8 on that number line. Then move up 8 units to arrive at 0. Afterward move the remaining 3 units to get to 3 on the number line. We've moved up a total of 8+3 = 11 degrees.
In other words, starting at -8 and moving up 11 units will have us arrive at 3
This visually shows -8+11 = 3

What is the equation of the line that passes through the point (-6, -2) and has a
slope of 1/6
Answer:
y=1/6x-1
Step-by-step explanation:
Recall that the equation of a line is y = mx + b.
m is the slopeb is the y-interceptWe know the line passes through (-6, -2), so we substitute x and y in the equation of a line. We also know the variable m (the slope) is 1/6. It would look something like this: -2=(1/6)(-6) + b.
From here, we can solve for b:
b + (1/6)(-6) = -2
b - 1 = -2
b = -1
The equation of the line that passes through the point (-6,-2) with a slope of 1/6 is y=1/6x-1.

Find an equivalent ratio in simplest terms: 30:18
Answer:
5:3
Step-by-step explanation:
To simplify the ratio, we have to divide both terms by the greatest common factor (GCF). The GCF is the highest number that can divide evenly into two or more numbers. The GCF of 30 and 18 is 6.
30/6 = 5
18/6 = 3
30:18 = 5:3

What is the slope of a line parallel to the line whose equation is 6x + 3y = -54
The slope of the line parallel to the line is -2
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the slope of the line parallel to the line?The line equation is given as
6x + 3y = -54
Subtract 6x from both sides
3y = -6x - 54
Divide through the equation by 3
So, we have
y = -2x - 17
A linear equation is represented as
y = mx + c
Where m represents the slope
This means that
m = -2
Parallel lines have the same slope
This means that the slope of the line parallel to the line is -2

Based on the fact that Mario increases by a scale factor of 2, the three points on the new Mario:
(7, 0)(0, 10.4)(4, 17.4)What are the new points?If Mario is increased by a scale factor of 2, then it means that all the points would be expanded by multiplying them by 2.
The first point would therefore be:
= 3.5 x 2 = 7
= 0 x 2 = 0
(7, 0)
The second point:
= 0 x 2 = 0
= 5.2 x 2 = 10.4
(0, 10.4)
The third point:
