Image attached pls help 40 points Jake is y years old. His grandma is 6 times his age. His cousin is 5 years older than
him.
a. Write an expression for each of their ages.
Grandma:
Cousin:
Jake:
b. What is the sum of all their ages? Write your expression in the simplest form.

8y + 5

Step-by-step explanation:

Jake: y

Grandma: y * 6

Cousin: y + 5

Sum: 8y + 5

- "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."

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
