Answer:
y = 3x - 10
Step-by-step explanation:
Starting with 3x - y = 10, add y to both sides:
3x = 10 + y
Then subtract 10 from both sides:
3x - 10 = y
If you switch the sides of the equation, it can also be written as:
y = 3x - 10
Answer:-4
Step-by-step explanation:
Well you see if you calculate 3.2 times 2 that will equal 6.4 but then if you divide that by 2 that will give you 3.2 so basically your answer is 6.4
The first thing you can find out is how many miles per hour he was driving, you divide 240 by 4 to get 60mph. From there you will take 240 and divide by 12 to get 20 mpg. So his car gets 20 miles per gallon and he is driving 60 miles per hour.
