Answer:

1. 23/20 miles, 2. 7/20 miles

Step-by-step explanation:

1. Total distance = 3/4 + 2/5

= (3*5)/(4*5) + (2*4)/(5*4)

= 15/20 + 8/20

= 23/20

= 1 3/20 miles

2. Difference between walked miles and jogged miles = 3/4 - 2/5

= 15/20 - 8/20

= 7/20 miles

Identify

1/2(8x - 4) = 2x

Step 2: Solve for x

[Distributive Property] Distribute 1/2: 4x - 2 = 2x
[Subtraction Property of Equality] Subtract 2x on both sides: 2x - 2 = 0
