Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
Find the value of x.
First, multiply -1 from both sides.
(-3/4x)(-1)<12(-1)
Solve.
12(-1)=-12
3/4x<-12
Next, multiply 4 from both sides.
4*3/4x<4(-12)
Solve.
Multiply the numbers from left to right.
4(-12)=-48
3x<-48
Then, divide by 3 from both sides.
3x/3<-48/3
Solve.
Divide the numbers from left to right.
-48/3=-16
X<-16
The correct answer is x<-16.
Answer:
a) 91 1/6 gallons
b) 2502 miles
Step-by-step explanation:
You are given a number of miles and a number of gallons for the car. The ratio of these numbers is ...
(261 mi)/(14.5 gal) = 18 mi/gal
We presume this value is constant for this car. Then the questions can be answered by forming and solving a proportion:
a) 1641 miles/(gallons) = 18 mi/(1 gal)
Multiplying by gallons and dividing by 18 mi/gal, we get
1641/18 gal = (gallons) = 91 1/6 gal
It will take 91 1/6 gallons of gasoline for Mary to drive to her friend's house.
___
b) Same deal, but the miles are unknown.
(miles)/(139 gal) = (18 mi)/(1 gal)
Multiplying by 139 gal gives ...
(18 mi)·139 = (miles) = 2502 mi
139 gallons of gasoline will let Mary drive 2502 miles.
Answer:
D.
Step-by-step explanation:
(1/6)*60 = 10
(1/6)*450 = 75
Check your work
75/10 = 7.5
