Answer:
car 2
Step-by-step explanation:
Divide distance by size gas tank size.
For car 1 : 360 /12 = 30 miles per gallon.
For car 2 : 490/14 = 35 miles per gallon etc.
Car3 and car 4 are lower, making car 2 economical with best gas mileage
Answer:
X= -6 (B)
Step-by-step explanation:
-3x=18
X=18/-3
X= -6
Answer:
Question 1: x = -75/38
Question 2: -5/6 X (-5/8) X 6/5 = 5/8
Step-by-step explanation:
Question 1: 3 4/5x - 2 1/2 for x = -10
Given equation is in whole number form so by simplifying we get:
19/5x - 5/2 = -10 (As 5*3 + 4 = 19 and 2*2+1 = 5)
Now Add 5/2 on both sides we get:
19/5x - 5/2 +5/2 = -10 + 5/2
19/5x = -10 + 5/2
Taking LCM we get:
19/5x = (-20+5)/2
19/5x = -15/2
Multiply both sides by 5/19
x = -15/2 * 5/19
x = -75/38
Question 2:
= -5/6 X (-5/8) X 6/5
Multiplying first 2 fractions we get:
= 25/48 X 6/5 ("-" multiplied by "-" gives "+")
- 25 in numerator will be cancelled from 5 in denominator giving 5
- 6 in numerator will be cancelled by 48 in denominator giving 8
= 5/8 X 1/1
Multiplicative identity
= 5/8
