Joel is training for a marathon. Right now he can run 3 miles. In two weeks he plans on running 5 miles, in four weeks he plans on running 8 miles.

If Joel's mileage continues growing with the same pattern, how many miles will he be running in 10 weeks?

A) 15
B) 17
C) 23
D) 26

c) 23

Step-by-step explanation:

The relationship between the amount of growth per 3 weeks is proportional.

If you made a table it would look similar to:

x      |          y  | Rate of Change

1      |          3  | +0

2     |          5  | +2

4     |          8  | +3

6     |         12  | +4

8     |          17 | +5

10    |         23 | +6

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
