A car wash has two employees on duty.
Employee I can finish washing a car in 30 minutes.
Employee 2 can finish washing a car in 20 minutes.
.
How long will it take the tiro employees to wash a car together?
Answer:
60 minutes
Step-by-step explanation:
Given that Employee I can finish washing a car in 30 minutes. and
employee 2 can finish washing a car in 20 minutes.
Assuming that both will wath the car together after n minutes.
So, n must be the integral multiple of 30 as well as 20.
For niminum value of n, n must be the lowest common factor of 30 and 20.
[tex]\Rightarrow n = LCM(30,20) \\\\\Rightarrow n = 60.[/tex]
Hence, after 60 minutes, they will wash a care togethre.
What is this? Solve for x: 3(x + 1) = −2(x − 1) + 6.
Answer:
[tex]x=1[/tex]
Step-by-step explanation:

if h(x)=(x/2)-6, find h(10)
A. -1
B. 14
C. 2
D. 7
Answer:
A
Step-by-step explanation:
if h(x)=(x/2)-6, find h(10)
What this means is that wherever there is an x on the right hand side, replace it with a 10
h(10) = (10/2) - 6
h(10) = 5 - 6
h(10) = -1
★PLSSSSS HELPPPPPPPPP★
Answer:
C: S≤35h+42
Step-by-step explanation:
Since the competitor charges $35 per hour PLUS 42(individually), it is 35h+42.
Suzzette's charges should be NO MORE than the competitor, so it could include the SAME amount too. So S(suzzette) is lesser than Or equal to 35h+42.
The answer is C, S≤35h+42

Which of the equations below represents a line perpendicular to the yaxis?
A. y= x
B. y= 6x
C. x = 6
D. y=-6
Answer:
y=x
Step-by-step explanation:
Answer:
D. y = -6
Step-by-step explanation:
You can graph each line to see which one is horizontal since the y-axis is vertical. This would make the lines perpendicular since when a vertical and horizontal line meet, they form a 90-degree angle, which is by definition what perpendicular means.

Each month, Diana donates the same amount of money to her favorite charity. If she donates $1,500 at the end of the year, how much did Diana donate each month?
Answer: Diana donates $125 each month.
Step-by-step explanation:
Let x = Amount of money Diana donates each month.
Money she donates in a year = 12x [ 1 year = 12 months]
Given: Money she donates in a year = $1500
So, [tex]12x=1500\Rightarrow\ x=\dfrac{1500}{12}=\$125[/tex]
i.e. Amount of money Diana donates each month = $125
Hence, Diana donates $125 each month.

And it not 12 feet cuz I already try that
Answer:
maybe 25 bc 37-12= 25
but also if u put it on top of the building then the bottom of the ladder on the bottom of the building aka ground it might be 25 ft
Answer:
35
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + b^2 = 37^2
144 + b^2 = 1369
1369 - 144 = 1225
sqrt of 1225 is 35

What is the x-intercept of the line 7x - 4y = 28
Answer:
(0, 4 )
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x, that is
7x - 4(0) = 28, that is
7x = 28 ( divide both sides by 7 )
x = 4 ← x- intercept ⇒ (0, 4 ) as an ordered pair

Answer:15-A
Step-by-step explanation:
Determine the intercepts of the line. 7x-5=4y-67x−5=4y−67, x, minus, 5, equals, 4, y, minus, 6 xxx-intercept: \Big((left parenthesis ,,comma \Big))right parenthesis yyy-intercept: \Big((left parenthesis ,,comma \Big))
Given:
The equation of line is
[tex]7x-5=4y-6[/tex]
To find:
The x and y-intercept of the given line.
Solution:
We have,
[tex]7x-5=4y-6[/tex]
Putting x=0, we get
[tex]7(0)-5=4y-6[/tex]
Add 6 on both sides.
[tex]0-5+6=4y[/tex]
[tex]1=4y[/tex]
Divide both sides by 4.
[tex]\dfrac{1}{4}=y[/tex]
So, the y-intercept is [tex]\left(0,\dfrac{1}{4}\right)[/tex].
Putting y=0 in given equation, we get
[tex]7x-5=4(0)-6[/tex]
Add 5 on both sides.
[tex]7x=-6+5[/tex]
[tex]7x=-1[/tex]
Divide both sides by 7.
[tex]x=\dfrac{-1}{7}[/tex]
So, the x-intercept is [tex]\left(-\dfrac{1}{7},0\right)[/tex].
Answer:
x intercept: (-1/7 , 0)
y intercept: (0, 1/4)

..........................................................................
. Volunteer drivers are needed to bring 80 students to the championship baseball game. Drivers either have cars, which can seat 4 students, or vans, which can seat 6 students. The equation 4c+6v=80 describes the relationship between the number of cars, c, and number of vans, v, that can transport exactly 80 students.
Select all statements that are true about the situation.
If 12 cars go, then 2 vans are needed.
c=14 and v=4 are a pair of solutions to the equation.
If 6 cars go and 11 vans go, there will be extra space.
10 cars and 8 vans isn’t enough to transport all the students.
If 20 cars go, no vans are needed.
8 vans and 8 cars are numbers that meet the constraints in this situation.
Answer:
3v +2c=32 students
Step-by-step explanation:
Answer:ALL OF THESE ARE TRUE
c=14 and v=4 are a pair of solutions to the equation.
If 20 cars go, no vans are needed.
8 vans and 8 cars are numbers that meet the constraints in this situation.
Step-by-step explanation:
1. If 12 cars go, then 2 vans are needed.(4)(12)+(6)(2) = 80
60≠80
False2.c=14 and v=4 are a pair of solutions to the equation.(4)(14)+(6)(4) = 80
80=80
True
3.If 6 cars go and 11 vans go, there will be extra space.(4)(6)+(6)(11) = 80
90≠80
False
4. 10 cars and 8 vans isn’t enough to transport all the students.(4)(10)+(6)(8) = 80
88≠80
False and is wrong because it would leave extra space
5. If 20 cars go, no vans are needed.(4)(20)+(6)(0) = 80
80=80
True
6. 8 vans and 8 cars are numbers that meet the constraints in this situation.(4)(8)+(6)(8) = 80
80=80
True
