Hich of the following word problems can be solved using the equation 10x−15=60? Select two that apply. A Kit buys 10 packages of batteries. After using a $15 coupon, the batteries cost $60. What was the original price, x, in dollars, of each package of batteries?

B Ursula bought 10 calculators at a store and paid $60. Each calculator was on sale for $15 off. What was the original price, x, in dollars, of each calculator?

C Siobhan originally has $15. After working as a waiter in a restaurant for $10 an hour, he now has $60. How many hours, x, did Siobhan work at the restaurant?

D Gary worked for 10 hours tutoring students at the library. He uses $15 to pay for gas on his way home. If he has $60 left after paying for gas, how much money, x, in dollars, was Gary paid per hour?

answer: $420.00

step-by-step explanation:   multiply $400.00 by 5%.

400.00*.05=20

400+20 = 420

i think is g(1)=-1.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
