Which situation can be represented by 80x > 150 + 50x?

V125BC [204]

Answer:

All numbers greater than 5, i.e., $x>5$ .

Step-by-step explanation:

The given inequality is

$80x>150+50x$

Isolate variable terms on one side to find the solution.

Subtract 50x from both sides.

$80x-50x>150+50x-50x$

$30x>150$

Divide both sides by 30.

$\dfrac{30x}{30}>\dfrac{150}{30}$

$x>5$

It means, all the numbers which are greater than 5, are the solutions of the given inequality and 5 is not included in the solution set.

Answer:

See below

Step-by-step explanation:

q = quarters value = .25 q

n = nickels = 4q value = .05 (4q)

summed = 12.60

.25q + .05(4q) = 12.60 <====== can be used to solve the problem

.45q = 12.60

q = 28 quarters then nickels = 4q = 112

The data in the table represent the fuel economy (mpg) for a car at different speeds (mph).

My graphing calculator computes the best match to a cubic function, which predicts mileage of about 39.7 mpg at 65 mph.

The second-best match is to a quadratic function, which predicts mileage of 29.8 mpg at 65 mph.

Linear regression predicts mileage of about 36.6 mpg at 65 mph.

It appears the best choice of those offered is (D) about 36 mpg.
