Vernon writes −2 3/10 as a fraction using the same method he knows for positive mixed numbers. His work is shown: Multiply the whole number by the denominator: −2⋅10=−20. Add the numerator: −20+3=−17. Write this number over the original denominator: −2 3/10=−17/10. Does this method work to correctly write −2 3/10 as a fraction? Complete the statements below to answer the question.

no

Step-by-step explanation: to change a fraction back to a improper fraction

multiply the whole number by the denominator and then add it to the numerator but be careful with negative.  You can check this process by changing the improper fraction back to proper. If i change -17/10 i get -1 7/10.  the correct answer is -23/10.      

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

- "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."
