Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
inequality : x<1 hope this helps:)!

Answer:
jada walks 0.6 miles farther after 3 hours
Step-by-step explanation:
jada walks at a speed of 3 miles per hour. elena walks at a speed of 2.8 miles per hour.
We find the distance both walked in 3 hours
distance = speed * time
Distance Jada walks = 3 * 3 = 9 miles
Distance Elena walks = 2.8 * 3= 8.4 miles
Now we find the difference of distance walked
Jada's distance - Elen's distance
9 - 8.4 = 0.6
jada walks 0.6 miles farther after 3 hours
