The car was driven 420 miles.
f(m) = 0.22m + 50
1. Substitute the total cost into f(m)
142.40 = 0.22m + 50
2. Subtract 50 from both sides
92.4 = 0.22m
3. Divide both sides by 0.22
420 = m
put it into an equation..
15+5v
sum is addition and product is multiplication
Step-by-step explanation:
Add all the books then find the average
The ratio is 4/3 because you add AC which is 12 and then divided 9 (BC) by 12
Answer:
Step-by-step explanation
You must find the common denominator for all of them.
A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.
B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.
C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.
D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
