Answer:
y = 2 - 1/2x
Step-by-step explanation:
So we are given the equation 3x + 6y = 12 and are ask to find y.
To find y you must isolate it first.
3x + 6y = 12
(Subtract 3x to isolate the y term)
6y = 12 - 3x
(Divide both sides by 6 to isolate the variable)
y = 2 - 3/6x
(Simplify)
y = 2 - 1/2x
And that is your answer since there is a second variable.
Answer:
The first option will take a total of 3.2 hours while the second option will take just 3 hours
This shows that the second option is faster
Step-by-step explanation:
Here, we want to compare two hiking options and see the one which is faster.
At any point in time;
Distance = speed * time
In the first option, he could hike at 3 mph for two hours.
Total distance covered would be 3 * 2 = 6 miles
Distance left = 12 miles - 6 miles = 6 miles
Time taken to hike 6 miles at 5 mph will be ; 6/5 = 1.2 hours
Total time for the first type hiking = 1.2 hours + 2 hours = 3.2 hours
For the second option;
Time = distance/speed = 12 miles/4 mph = 3 hours
We can see that the second option is faster
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
So multiplication first, 56*2= 112
Division second, 5/5=1
Subtraction last, so 112 - 1 = 111
111 is the answer.
