Answer:
Could you explain it another way?
Step-by-step explanation:
C
Unit rate means that the denominator of the units has to be 1: units have to be miles/1 hour
Thus divide miles by hours to get the unit rate. The answer would then be 7/2 miles/1 hour
1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)
1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y
0,7x + 5,88y - 0,7x + 5,25y
0,7x - 0,7x + 5,88y + 5,25y
11,13y
60*80%=
60*0.8 = 48
one of your choices should be 48 or something close to 48
B C D F
well first 4(3+x) simplified would be 12+4x and that is C so thats why C is an answer than it would b
