Step-by-step explanation:
Darla 8h
Lonnie 6h
They both worked 3 hours now
subtract
8-3=5
6-3=3
Darla have 5 hours to finish
and...
Lonnie has 3 hours to finish
all together is 8 hours in all
1/8 part of the job is left to be finished if both Darla and Lonnie works for three hours on the job.
What is Fractions?Fractions are the part or portion of a whole.
For example, fraction 1/2 means 1 part of the 2.
Time taken by Darla to do the job = 8 hours
Time taken by Lonnie to do the job = 6 hours
Let J represent the job.
In 8 hours, Darla completes J.
In 3 hours, Darla completes 3/8 J
In 6 hours Lonnie completes J.
In 3 hours, Lonnie completes 3/6 J.
The work completed = 3/8 J + 3/6 J
= J [ 3/8 + 3/6]
= J [3/8 + 1/2]
= 7/8 J
7/8 parts of the job is completed.
Job left to finished = J - 7/8 J = 1/8 J
Hence 1/8 part of the job is left to be finished.

fill in the table using this function rule. y=2x+5. 1 ( ) 4( ) 5( ) 10( ) please help and dont make it complicated
Answer:
The complete table is as follows:
x y
1 7
4 13
5 15
10 25
Step-by-step explanation:
Given the function
[tex]y=2x+5[/tex]
Given the table
x y
1 blank
4 blank
5 blank
10 blank
Substitute x = 1 in the function
y = 2x+5
y = 2(1)+5 = 2+5 = 7
so, when x = 1, y = 7 i.e. (1, 7) is the point on the table
Substitute x = 4 in the function
y = 2x+5
y = 2(4)+5 = 8+5 = 13
so, when x = 4, y = 13 i.e. (4, 13) is the point on the table
Substitute x = 5 in the function
y = 2x+5
y = 2(5)+5 = 10+5 = 15
so, when x = 5, y = 15 i.e. (5, 15) is the point on the table
Substitute x = 10 in the function
y = 2x+5
y = 2(10)+5 = 20+5 = 25
so, when x = 10, y = 25 i.e. (10, 25) is the point on the table
Therefore, the complete table is as follows:
x y
1 7
4 13
5 15

Mischa and Ben's combined SAT score was 2290. Ben and Ashley's
combined score was 2530. Mischa and Ashley's combined score was
2660. Find each student's individual SAT score.
Answer:
Ashley=1450
Ben= 1080
Mischa= 1210
Step-by-step explanation:
M= Mischa
B= Ben
A= Ashley
M+B=2290
A+B=2530
M+A=2660
M-A= -240
so 2M = 2420, and M= 1210
Then
1210 + B = 2290
B= 1080
Then
1210 + A= 2660
A= 1450

Step-by-step explanation:
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
Line of "rise": (0, 3) to (0, 0) ==> -3 units
Line of "run": (0, 0) to (1, 0) ==> 1 unit
Slope: rise/run ==> -3/1
Step-by-step explanation:
Slope is basically a ratio of changes in the y-value to changes in the x-value. What I mean by that is the slope shows how much the line goes up or down compared to how much the line goes left or right. In this case, the line goes right one unit for every 3 units the line goes down. Taking a look at the portion of the line in Quadrant 1 (top right quadrant), the line starts at (0, 3) and ends at (1, 0). I guess that's another way to figure out slope, too: line up the two coordinates (the leftmost one above the rightmost one), and add or subtract.
Like this:
(0, 3)
(1, 0)
+1 -3
Since the formula for slope is rise/run (y-difference/x-difference), the slope is therefore -3/+1, or simply -3/1. (You don't include plus signs.)

The sum of two numbers is 40 and the difference is 16. What are the numbers?
Answer:
28 and 12
Step-by-step explanation:
The sum of two numbers is 40 and the difference is 16. What are the number? x+y=40 Substitute for x from above. (y+16)+y=40 Subtract 16 from each side.
The two numbers whose sum is 40 and difference is 16 are 28 and 12.
Let's denote the two numbers as x and y. We are given the following information:
x + y = 40 (equation 1)
x - y = 16 (equation 2)
To solve for x and y, we can use a method called elimination or substitution. Let's use the elimination method here.
Adding equation 1 and equation 2, we eliminate the y term:
(x + y) + (x - y) = 40 + 16
2x = 56
x = 28
Now we can substitute the value of x back into equation 1 to solve for y:
28 + y = 40
y = 40 - 28
y = 12
Therefore, the two numbers are 28 and 12.

A rectangular swimming pool is twice as long as it is wide. A small concrete sidewalk surrounds the pool and is a constant 2 feet wide. The total area of the pool and sidewalk is 160 square feet. Find the dimensions of the pool
Answer:
The dimensions of the pool are:
Width: 8.944 feet
Length: 17.888 feet
Step-by-step explanation:
From Geometry, the area of a rectangle ([tex]A[/tex]), measured in square feet, is determined by the following equations:
[tex]A = w\cdot l[/tex] (1)
Where:
[tex]w[/tex] - Width, measured in feet.
[tex]l[/tex] - Length, measured in feet.
If we know that [tex]w = x[/tex], [tex]l = 2\cdot x[/tex] and [tex]A = 160\,ft^{2}[/tex], then we get the following second order polynomial:
[tex]2\cdot x^{2}-160 = 0[/tex] (1)
And we solve the expression for [tex]x[/tex]:
[tex]2\cdot x^{2} = 160[/tex]
[tex]x^{2} = 80[/tex]
[tex]x = \sqrt{80}\,ft[/tex]
[tex]x \approx 8.944\,ft[/tex]
Then, the dimensions of the pool are, respectively:
[tex]w \approx 8.944\,ft[/tex] and [tex]l \approx 17.888\,ft[/tex]
