Answer: Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 12 hours
Step-by-step explanation:
Let x= Time taken by Ximena to paint the fence alone .
Time taken by Candice to paint the fence alone = x-12
As per given , we have
[tex]\dfrac{1}{x}+\dfrac{1}{x-12}=\dfrac{1}{8}\\\\\Rightarrow\ \dfrac{x-12+x}{x(x-12)}=\dfrac{1}{8}\\\\\Rightarrow\ 8(2x-12)=x^2-12x\\\\\Rightarrow\ 16x-96=x^2-12x\\\\\Rightarrow\ x^2-12x-16x+96=0\\\\\Rightarrow\ x^2-28x+96=0\\\\\Rightarrow\ x^2-4x-24x+96=0\\\\\Rightarrow\ x(x-4)-24(x-4)=0\\\\\Rightarrow\ (x-4)(x-24)=0\\\\\Rightarrow x=4, 24[/tex]
if x= 4
Time taken by Ximena = 4 hours
Time taken by Candice = 4-12 hours =-8 hours which is not possible. (time cannot be negative)
Therefore, x= 24
Such that
Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 24-12=12 hours
Can you divide 38 by 4 evenly? Use the number line to explain your answer. 38 You cannot divide 38 by 4 evenly. Using the number line, you can count back from 38 by 4s times until you reach the number . Then you cannot count back by 4 any more, so the remainder is .
Answer:
No there will be 2 left.

count backwards from 38 by 4's
Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100
Answer:
because both result in the equation 10 x = 1,000, which simplifies to x = 100
Step-by-step explanation:
50 / x = 10/20
Cross product
50 * 20 = x * 10
1000 = 10x
x = 1000 / 10
= 100
10/50 = 20/x
Cross product
10 * x = 50 * 20
10x = 1000
x = 1000/10
= 100
The answer is :
because both result in the equation 10 x = 1,000, which simplifies to x = 100

which equation represents a line which is parallel to the line y=-2/3x-1
Answer:
Step-by-step explanation:
The first step is to get the given equation to look like the answers provided.
y = - 2/3 x - 1 multiply by 3
3y = -2x - 3 add 2x to both sides
3y +2x = - 3
Only the answer on the lower left looks the left side of the above equation.

4x-3y=9
x-3y=6 solve the following systems of equations by graphing
The solution of the systems of equations is (1, -1,667).
What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought
Given that, a system of equations, we need to solve them graphically,
The equation are =
4x-3y = 9....(i)
x-3y = 6....(ii)
To solve by graphically, we will first plot the graph,
Finding the coordinates for same,
Equation (i)
4x-3y = 9
Put x = 0,
y = -3
a) (0, -3)
Put x = 3,
y = 1
b) (3, 1)
Equation (ii)
x-3y = 6
Put x = 0,
y = -2
c) (0, -2)
Put x = 3,
y = -1
d) (3, -1)
Therefore, we get the coordinates of the equations, now when we plot the graph, both the lines will intersect at a point and that point will be the solution of the systems of equations,
The lines are intersecting at (1, -1,667).
Hence, the solution of the systems of equations is (1, -1,667).

On a field trip, there are 8 adults and 24 students. What is the ratio of students to the total number of people on the field trip? 8 to 24 1 to 4 32 to 24 3 to 4
Answer:
1/4!
Step-by-step explanation:
8 + 24=32
32 ÷ 8 = 4
8x4=32
There is only one 8 so it would be 1/4
Hope this made sense :)
Answer:
The ration is 24:32, or 3:4
Step-by-step explanation:
I know you don't care about an explanation, and just want the answer, but I'll still explain it.
The total people on the trip are the number of kids+the number of adults. We get 32.
Now, the number of kids on the trip is 24 right? The ratio right now is 24:32. We can simplify this dividing the entire thing by 8, so the number isn't as big. Once we do that, we see that our answer is 3:4

Answer:
88
Step-by-step explanation:
m<ACB is equal to m<ABC because when to split the triangle down the middle and reflect one half you would have the same open shape. So by knowing that, you add 46+46 to get 92. Also knowing a triangle is equal to 180, you would end up subtracting 92 from 180 to get 88.

write an equation for a line through (1,-1) and (2,3)
Answer:
y = 4x - 5
Step-by-step explanation:
Use the point slope form and add in the ordered pairs [tex]\frac{3 + 1}{2 - 1}[/tex] , and once you solve this it equals [tex]\frac{4}{1}[/tex], or just 4. Now you have the first part of your equation, y = mx + b, but now you have y = 4x + b. To find b, substitute the x and y values of one of the given ordered pairs in for x and y in the equation, and I am using (2,3). The equation now looks like this: 3 = 4(2) + b. Now solve: 3 = 8 + b
Subtract 8 from both sides to get -5 = b. Now you have a full equation: y = 4x -5
