You can multiply both sides by a number that will get rid of the denominators. For ex. you can multiply the first equation by 12 because 4 and 3 both go into 12 evenly. MAKE SURE YOU MULTIPLY THE OTHER SIDE BY 12 AS WELL! Therefore, 12(x/4) - 12(y/3) = 12(1), or 3x - 4y = 12
Research scientists use a standard practice called the _____ method to help them understand phenomena.
Answer:
y = 3/2 when x = 15
Step-by-step explanation:
y = k / √1+x
2 = k / √1+8 = k/3
k = 6
y' = 6 / √1+15 = 6/4 = 3/2
24 miles = 326 gallons
divide each side by 24: 1 mile = 13.583 gallons
round: 13.6 miles per gallon
Answer:
(D)
x + (x + 2) + (x + 4) = 66
