3 3/5 + v + 5 2/3 = 15
18/5 + v + 17/3 = 15
54/15 + v + 85/15 = 225/15
v = 225/15 - 139/15
v = 86,/15 = 5 11/15, answer B
Answer: 12.4 + 1.1x + 2.2x^2 + 2.3x^3

Answer:
Step-by-step explanation:
1st way:
Solve directly
6p=0.6(5p+15)
Open bracket
6p = 3p + 9
Collecting like terms
6p - 3p = 9
3p = 9
Dividing by 3
p = 9/3
p = 3
2nd way:
6p=0.6(5p+15)
Convert the decimal to fraction
6p= 6/10(5p+15)
6p= 3/5(5p+15)
6p= 3/5(5p) +3/5(15)
6p = 3p + 9
Collecting like terms
6p - 3p = 9
3p = 9
Dividing by 3
p = 9/3
p = 3
Answer:
325 miles to the nearest mile.
Step-by-step explanation:
Average gasoline consumption over the 5 weeks
= miles travelled / gasoline used
= (198 + 115 + 154 + 160 + 132) / (9 + 5 + 7 + 8 + 6)
= 21.69 miles per gallon.
Estimate of number of miles you can drive on 15 gallons
= 15 * 21.69
= 325 miles.
