Answer:
I believe the duration for $89.00 is 2 hours
Step-by-step explanation:
We start off with the $17 dollars and calculate 36.00+36.00 for a total of $89. Therefore, (120 mins)/60=2 hours.
Because this is a linear problem, I'd use the slope-intercept formula:
[tex]y = mx + b[/tex]
where
m = slope (rise/run)
y = dependent value
x = independent value
b = constant value
Because the plumber charges $17 upon arrival, it is our constant. The $36 is our slope (per hour, per minute, per etc. is generally a give away). Additionally because the total cost of the plumber's visit depends on how long s/he stays at a client's home, the $89 is our y value. Therefore the equation should look like this:
[tex]89 = 36x + 17[/tex]
Solve for x by subtracting 17 from both sides of the equation then dividing by 36.
[tex]72 = 36x[/tex]
[tex]2 = x[/tex]
The plumber spent two hours at his/her client's home.

Answer:
8m + 5/m -10 m^2
Step-by-step explanation:
24m^4 / 3m^3 = 8m
15m^2 / 3m^3 = 5/m
- 30m^5 / 3m^3 = -10m^2
Putting these back together
8m + 5/m -10 m^2

Answer:
37.5 miles per hour
Step-by-step explanation:
To find the miles per hour, you divide the miles by hours. If you divide 225/6, you get 37.5. You can double check this by dividing another set, like 450/12 and see that you still get 37.5. Hope this helps! :)

K is the midpoint of J and L, then find x.
Given: JK = 5x - 3
KL = 3x + 1
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
K is the midpoint of J and L, so
JK = KL.
[tex]5x-3=3x+1[/tex]
Add 3 to both sides:
[tex]5x-3+3=3x+1+3[/tex]
[tex]5x=3x+4[/tex]
Subtract 3x from both sides:
[tex]5x-3x=3x+4-3x[/tex]
[tex]2x=4[/tex]
Divide 2 on both sides:
[tex]\frac{2x}{2}=\frac{4}{2}[/tex]

Greetings from Brasil....
Let's solve this 2nd degree equation.
6b² + 8b - 10 = 0 dividing all terms by 2
3b² + 4b - 5 = 0 applying the baskara formula
Δ = 4² - 4 · 3 · (- 5)
Δ = 76
b = (- 4 ± √76)/6 so

Step-by-step explanation:
-4.5x -2y = -12.5 -------(1)
3.25x -y = -0.75 --------(2)
From (2) we can make y the subject of the relation
y = 0.75+3.25x -------(3)
Input 0.75+3.25x into y in (1)
-4.5x -2(0.75+3.25x) = -12.5
-4.5x -1.5- 6.5x = -12.5
-4.5x -6.5x -1.5 = -12.5
-11x = -12.5 +1.5
-11x = -11
x = 11/11
x = 1
If x = 1,substitute 1 into x in (3)
y = 0.75+3.25x
y = 0.75 +3.25(1)
y = 0.75 +3.25
y = 4
x = 1,y = 4

Alex has 84 quarters and nickels worth a total of $17.80. Which equation can be used to find q, the number of quarters Alex has? 0.25q + 0.05(q – 84) = 17.80 0.05q + 0.25(84 – q) = 17.80 0.25(q – 84) + 0.05q = 17.80 0.05(84 – q) + 0.25q = 17.80
Answer:
D
Step-by-step explanation:
The equation can be used to find q is 0.05(84 - q) + 0.25q = 17.80 option (D) 0.05(84 - q) + 0.25q = 17.80 is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Alex has 84 quarters and nickels worth a total of $17.80.
As we know,
1 nickel = 5 cents
1 dime = 10 cents
1 quarter = 25 cents
1 dollar = 100 cents
The amount that Alex = 84 quarters + $17.80
q = 84 quarters + $17.80
q is the number of quarters Alex has.
Remaining nickel value = 84 - q
In cents:
= 0.05(84 - q)
q in cents:
= 0.25q
0.05(84 - q) + 0.25q = 17.80
Thus, the equation can be used to find q is 0.05(84 - q) + 0.25q = 17.80 option (D) 0.05(84 - q) + 0.25q = 17.80 is correct.

Let f(x)=-3x and g(x) = 2x-1
Find the following: 4g(x) - f(x)
Answer:
11x-4
Step-by-step explanation:
f(x)=-3x
g(x) = 2x-1
4g(x) - f(x)
4(2x-1) - ( -3x)
Distribute
8x -4 +3x
Combine like terms
11x-4
Here, we are provided with two polynomials f(x) and g(x),and we need to find 4g(x) - f(x).
Given,
f(x) = -3xg(x) = 2x - 1Now,we need to find 4g(x) - f(x). We will simply substitute the given value of polynomials to get the answer.
[tex]4g(x) - f(x)[/tex]
[tex]4(2x - 1) - ( - 3x)[/tex]
Opening the parentheses,
[tex]8x - 4 + 3x[/tex]
Now combing the like terms, and adding them,
[tex]8x + 3x - 4[/tex]
[tex] \boxed{11x - 4}[/tex]
This is our final result.

Bonjour je suis en 3 ème pouvez vous m'aider s'il vous plaît une voiture met 2 h 30 pour faire 200 km 1. Calculer sa vitesse moyenne en km/h 2. Calculer la distance parcourue en a ) 3h 15 b) 42 min c) 3h 36 min 3. Calculer le temps mis pour parcourir 540 km
Répondre:
Explication étape par étape:
Vitesse = Distance / Temps
Distance donnée = 200 km
Durée = 2 h 30
Convertir le temps en heures
Depuis 60 minutes = 1h
2 heures 30 minutes = 2+ (30/60)
2h30 = 2 + 1/2 hors
2 heures 30 minutes = 2,5 heures
Vitesse en km / h = 200 km / 2,5 h
Vitesse en km / h = 80 km / h
D'où sa vitesse moyenne en km / h est de 80 km / h
a) Distance = Vitesse * Temps
Vitesse donnée = 80 km / h
Durée = 3h15
Temps = 3 15/60 h
Durée = 3,25 h
Distance = 80 * 3,25
Distance parcourue en 3h15 = 260 km
b) Distance = Vitesse * Temps
Vitesse donnée = 80 km / h
Durée = 42 minutes
Durée = 42/60 h
Distance = 80 * 42/60
Distance = 3360/60
Distance = 56 km
Distance parcourue en 42 minutes = 56 km
c) Distance = Vitesse * Temps
Vitesse donnée = 80 km / h
Durée = 3 h 36 minutes
Temps = 3 36/60 h
Durée = 3,6 h
Distance = 80 * 3,6
Distance = 288 km
Distance parcourue en 3 h 36 min = 288 km
d) Distance donnée = 540 km
Vitesse = 80 km / h
Temps = Distance / Vitesse
Heure = 540/80
Temps = 6,75 heures
Par conséquent, le temps nécessaire pour parcourir 540 km est de 6,75 heures

Answer:
See below.
Step-by-step explanation:
******************************************************************************
Kate buys 10 tickets to a show. She also pays a $5 parking fee. She spent $35 to see the show.
Each ticket costs x.
10 tickets cost 10x.
Parking is $5.
Total is $35
10x + 5 = 35
******************************************************************************
Ram has 35 gel pens. He gives an equal number of pens to each of his 5 friends and has 10 pens left for himself.
The number of pens he gives each friend is x.
The total number he gives is 5x.
He started with 35 pens ands ended up with 10 pens.
35 - 5x = 10
5x + 10 = 35
******************************************************************************
Yin spends 10 hours on homework this week. She spends 5 hours on science homework and then answers 35 math problems.
Total time spent on homework is 10 hours.
Science homework is 5 hours.
She spends x time on each of the 35 problems, so the total time spent of the 35 problems is 35x.
35x + 5 = 10
