Answer:
Step-by-step explanation:
A copy machine can copy a report in 30 mins. When a second copy machine is used at the same time, the copying can be sone in 18 min. How long would it take the second copu machine to do the copying alone?
i have:
x=30
x+y=18
that would be -12..not right?
The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.
Calculation of the time taken:Let we assume x be the time required at the time when using both machines.
Let us assume the completed job = 1
we know that
copy machine 1 will do [tex]x/30[/tex] of the job
and
copy machine 2 will do [tex]x/18[/tex] of the job
So, it can be like
[tex]\frac{x}{30} + \frac{x}{18} = 1[/tex]
So,
18x + 30x = 540
48x = 540
x = 11.25 minutes
hence, The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

$22 haircut; 20% tip
help..
Answer:
20% tip = $4.40; total = $26.4
Step-by-step explanation:
20 % = 0.20 ------> 22 * 0.20 = 20% of 22
20% of $22.00 = $4.40
total = $22.00 + $4.40
total = $26.40

Answer:
Equation of the Line: y = 1.25x + 5
Equation in Standard Form: 5x - 4y = -20
Step-by-step explanation:
y = mx + b
[tex]\frac{17.5 - 22.5}{10 - 14}[/tex] = [tex]\frac{-5}{-4}[/tex] = [tex]\frac{5}{4}[/tex] or 1.25
y = 1.25x + 5
Ax + By = C (A must be positive, and no fractions or decimals)
y = 1.25x + 5
-1.25x + y = 5
times -4
5x - 4y = -20
Identify the slope (m) and y-intercept (b) of each linear equation.
52. 3x+4y=24
Answer:
Step-by-step explanation:
[1] 3x - 4y = -24
[2] -x - 16y = -52
Graphic Representation of the Equations :
-4y + 3x = -24 -16y - x = -52
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -16y + 52
// Plug this in for variable x in equation [1]
[1] 3•(-16y+52) - 4y = -24
[1] - 52y = -180
// Solve equation [1] for the variable y
[1] 52y = 180
[1] y = 45/13
// By now we know this much :
x = -16y+52
y = 45/13
// Use the y value to solve for x
x = -16(45/13)+52 = -44/13
Solution :
{x,y} = {-44/13,45/13}

Line BC is represented by 3x + 2y = 8. Line AD is represented by –3x – 2y = 6. What is the relationship of line BC to line AD? Explain how the sum of the equations demonstrates this relationship.
Answer:
2
Step-by-step explanation:
if you suntract the 2 you, 3x cancels 2y cancels, 8-6 is 2
Answer: Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.

Tony hangs lights in his back yard. The rule c=14f gives the number of lights, c, there are for each foot, f, of wire. How many lights are on 8 feet of wire?
Answer:
112 lights
Step-by-step explanation:
The rule c=14f gives the number of lights, c, there are for each foot, f, of wire.
We need to find the number of light on 8 feet of wire.
Put f = 8 in the given rule equation
c = 14 × 8
= 112
Hence, there are 112 lights on 8 feet of wire.

a relation is defined by the points (1,4), (3,-1), (-1,-2) and (1,-3)
this relation (is) (is not) a function because there (is no x-value) (is one x-value) (are two x-values) corresponding to multiple y-values.
Answer:
The answer is that the relation is not a function. because there are two x-values corresponding to multiple y-values
Step-by-step explanation:
Here we want to explain why the given set of points do not represent a function
For a function, we can have same y value for different x value
But, we cannot have same x value for different y value
The sets of point given however has 2 y-values having same x value and as such the points cannot form a function (1,4) and (1,-3)
