We know that 4 and below rounds down and 5 and above round up
That means she walked 3.5 miles her sister walked 1.2 miles
and her brother walked 0.9 miles
1.2+0.9=2.1
3.5-2.1=1.4
B about 1.4 miles
Combine like terms.
3x+(x-8)= 120
4x-8= 120
Add 8 to both sides.
4x= 128
Divide by 4 into both sides.
x= 32
I hope this helps!
