After arianna completed some work, she figured she still had 78 21/100 pictures to paint. if she completed another 34 23/25 pictures, how many pictures did arianna still have to paint Plz be a long answer

43 29/100

Step-by-step explanation:

Subtract 34 23/25 from 78 21/100.

To do this, you have to turn 23/25 to something over 100.

Multiply the numerator and denominator by 4, since that is how you get 25 to 100. This will give you 92/100. So now you have 32 92/100

You have to take away one from 78, which makes it 77 and then add 100 to 21, since 100 is equal to 1.

You now have 77 121/100 - 32 92/100.

77 121/100 - 32 92/100 = 43 29/100

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

- "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."
