Olaf needs a total of 3 cups of sugar to make 4 cakes. Write and solve an equation to find the number of cups of sugar he needs for each cake. Which number line shows the number of cups of sugar Olaf needs for each cake?

I will be phrasing the number of cups of sugar as s, and the number of cakes as c.

3s = 4c

3 divided by 4 = 0.75

0.75s = 1c

For 1 cake, Olaf needs 0.75 cups of sugar.

Hope it helps! :)

answer: 177/8

step-by-step explanation:

- "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."
