Answer: Amy scored 13,281 points
Step-by-step explanation:
Given : Connor scored 14,370 points in a game .
Amy scored 1,089 fewer (less than) points than Conor .
By using the SUBTRACTION OPERATION, the number of points scored by Amy will be :-
⇒ The number of points scored by Amy = 13,281
Hence, Amy scored 13,281 points .

70(h + 2)
70(h - 2)
70h
Answer:
After 7.8 hours (7 hours 48 min.) will the bus and car be 800 miles apart
70(h-2) expression represents the number of miles the car travels.
Step-by-step explanation:
If h represents the number of hours the bus travels.
In the question it is said that the bus leaves 2 hours before the car does
Therefore car travels (Time) = ( h-2 )
car's speed = 70 mph,
Distance = speed × time = 70(h-2)
70(h - 2) expression represents the number of miles the car travels.
If we want to find the number of hours will the bus and car be 800 miles apart we can solve it as :
50h + 70(h-2) = 800
50h + 70h - 140 = 800
120h = 800 + 140
120h = 940
h = 940 ÷ 120 = 7.833... = 7.8 hours (7 hours and 48 min.)
Ans. After the bus left the city, after 7.8 hours the car and the bus will be 800 miles apart.

Answer:y = 0.8x and y = -0.12x2 + 20
Step-by-step explanation:
x + a (over(fraction)) ax = b (over(fraction)) x
Part 1. Show all work to solve for x in the equation and check the solution.
Part 2. Explain how to identify the extraneous solution and what it means.
Answer:
x = 7 is a solution
x = -2 is an extraneous solution.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using the equation below as a model, fill in numbers in the place of a and b to create a rational equation that has an extraneous solution.
X + 4 / 4x = 8 / x
Part 1. Show all work to solve for x in the equation and check the solution.
X + 4 / 4x = 8 / x
x(x + 4) = (4x)8
x^2 + 4x = 32x
x^2 + 4x - 32x = 32x - 32x
x^2 - 28x = 0
x(x - 28) = 0
X = 0 or x = 28
Part 2. Explain how to identify the extraneous solution and what it means.
The solution x = 0 is extraneous because you are not allowed to divide by 0.
