Olivia takes a trip to visit her aunt who lives 120 mi. away. Olivia's car can travel 24 miles per gallon of gasoline. If gasoline costs 03 per gallon, how much will Olivia pay for the gasoline for this trip? Show or explain your reasoning.
Answer:
$15
Step-by-step explanation:
Given that :
Aunt's distance = 120 miles
Miles per gallon of Olivia's car = 24 miles per gallon
Cost of gasoline = 3 per gallon
Cost of gasoline for the trip :
(Aunt's distance / miles per gallon) * cost of gasoline per gallon
(120 miles / 24 miles per gallon) * 3
5 * 3 = $15
Cost of gasoline for the trip = $15
how to solve using Substitution or Elimination?
y=3x-1
y=2x+2
By elimination:
y = 3x - 1
y = 2x + 2
Subtract the second equation from the first
0 = x - 1
y = 2x + 2
Subtract the first equation from the second
0 = x - 1
y = x + 3
Subtract the first equation from the second again
0 = x - 1
y = 4
Subtract x from both sides of the first equation
- x = - 1
y = 4
Divide the first equation by (-1)
x = 1
y = 4
So, the solution is x = 1 and y = 4 {or: (1, 4)}If , which equation describes the graphed function? A. y = f(-x) − 3 B. y = -f(x) + 3 C. y = -f(x) – 3 D. y = f(-x) + 3
Answer:
y=-f(x)-3
Step-by-step explanation:
when f is negative it is reflected over the x-axis and -3 means to translate 3 units down
y = -f(x) – 3 describes the graphed function.
When f is negative it is reflected over the x-axis.
-3 means to translate 3 units down.
How do you identify a function?By using inspecting the inputs (x-coordinates) and outputs (y-coordinates), you could decide whether or no longer the relation is a function. Keep in mind, that this is a feature each input has only one output.

Answer:
B. The student multiplied 380 by [tex]\frac{19}{20}[/tex].
Step-by-step explanation:
In the equation -[tex]\frac{3}{4}[/tex]y - [tex]\frac{1}{5}[/tex]y = 380, we can further evaluate the equation into:
-[tex]\frac{19}{20}[/tex]y = 380
To find y, we need to multiply 380 by the inverse of the fraction on the other side, which is -[tex]\frac{20}{19}[/tex]. However, the students multiplied 380 by [tex]\frac{19}{20}[/tex] to get 361. Thus, this was the mistake.

Patricia and her brother Ian help themselves to a pitcher of lemonade on the kitchen counter. Patricia takes a glass and fills it with p ounces of lemonade. Ian takes a bigger glass and pours himself 20% more lemonade than Patricia poured in her glass. Write an expression to represent the quantity of lemonade(in ounces) in Ian’s glass in terms of the quantity in Patricias glass (p).
Part A- Write an expressionism terms of p that shows how many more ounces Ian poured in his glass than Patricia poured in hers.
Part B-Write an expression in terms of p to represent the amount of lemonade (in ounces) Ian poured in his glass. Include two terms in your expression.
Part C- combine the like terms in the expression from part B to create an equivalent expression.
Part D- using the simplified expression you wrote in part C, and domain what it means to have 30% more of a given quantity.
Part E- suppose that Patricia drinks one-fourth of the lemonade in her glass. Write an expression in terms of p that represents the number of ounces Patricia drank.
Part F- in part E, Patricia drank one-fourth of the lemonade in her glass. Write and expression in terms of p that represents the number of ounces Patricia has left in her glass. Include two terms in your expression.
Part G- combine the like terms in the expression from part F to create an equivalent expression.
Part H- using the simplified expression you wrote in part G, explain what it means to have 1/4 less of given quantity.
Please help me I’m struggling on this!
Answer:
Part A: 0.20p or 0.2p (doesn't matter which one you use)
Part B: p + 0.2p
Part C: p + 0.2p = 1p + 0.2p =
1.2p
Part D: increasing a quantity by 20% is the same as multiplying the quantity by 1.2
Part E: 1/4p ounces
Part F: p - 1/4p
Part G: = 3/4p
Part H: decreasing a quantity by 1/4 is the same as multiplying the quantity by 3/4

1. Greg bought a huge Christmas tree. He had to pay a
25% advance to reserve the tree. How much did he pay
to reserve the tree if the cost of the tree is $300?
Answer:
Answer: $1,200
Step-by-step explanation:
Since multiplying 25% would take off 25% from 300, do the opposite (aka divide .25 from 300).
300/.25 = 1,200
Bunty goes 500 km from Delhi towards East direction. Bubly goes 200 km for Delhi towards
West direction. What is the distance Bubly has to cover to reach Bunty?
the ans is:700km
plz explain me
Answer:
700 km
Step-by-step explanation:
Distance covered by Bunty = 500 km
Distance covered by Bubbly = 200 km
Displacement between them = 500 + 200 km = 700 km
This means Bubbly has to cover a distance of 700 km to reach Bunty.

A plumber charges his customers $25.70 per hour, h, plus a $54.50 service fee.On Tuesday,he earns $118.75 for fixing Mrs.Goodwill's sink. How long does it take the plumber to fix Mrs.Goodwill's sink
Answer:
2.5 hours
Step-by-step explanation:
Given that :
Charge per hour = 25.70
Service fee = $54.50
If total earning = 118.75 ; how many hours did it take to fix the sink?
Let number of hours = x
Total earning = service fee + (charge per hour * number of hours)
118.75 = $54.50 + (25.70x)
118.75 - 54.50 = 25.70x
64.25 = 25.70x
x = 64.25 / 25.70
x = 2.5
Hence, it took 2.5 hours to fix the sink
The Sloan family stayed in a hotel room for 6 nights while on vacation. The total cost before tax was $1,170. If the hotel room tax rate in the city is 12%, what was the total cost for the hotel room?
Answer:
Total cost for the hotel room is $1310.4
Step-by-step explanation:
The total cost before tax was $1170.
The tax rate is 12%.
So, tax paid = 12%(1170)
Convert 12% to decimal. We get 12% as 0.12
So, tax =0.12*1170 =140.4
So, total cost for the hotel room = $140.4 +$1170 =$1310.4

Answer:
(-1,-2)
Step-by-step explanation:
D's original postion/location is at (1,-2)
You basically take the point D and keep your y coordinate, -2, the same /constant and change your x coordinate (flip the sign)
So keeping the y-coordinate constant, -2 changing positive 1 to negative 1
So.. D's location reflected on the y axis is (-1,-2)
*Let's Say: D was reflected on the x-axis you would do the opposite by keeping the x coordinate constant and flipping the y-coordinate sign (to positive)
So...
D's location reflected on the x-axis is (1,2)
