Answer:
2.8+.55x=5 x=4
Step-by-step explanation:
5-2.8=2.2
2.2/.55=4
This means that if the model is 1 in lengh then th ereal car is 20 times of that or 20 in legnth
so to find the answer, just multiply model by 20
8.7 =model
real=8.7 times 20=174
real car is 174 inches
12 inches=1 foot
conversion factor
1 ft/12in=1=convesion
so
174 times 1/12=14 and 6/12
the answer is 14 feet and 6 inches or 14.5 feet
15+32=47. 180-47=133. answer=133
