2(3+1+2) is equivalent to 12
Answer:
The equation is x=3 because y can be any number but x can only be three for this line.
To solve for x means to put x on one side, and everything else on the other side.
Let's do that:
And now we have to divide with -a.
Be careful: When dividing with anything that's negative, you have to reverse the inequality.
Final solution:
Step-by-step explanation:
150 km in 3 hours
= 150 ÷ 3 = 50km/h
Remaining distance = 560 - 150 = 410
Remaining hours = 8 - 3 = 5
Then average speed = 410 ÷ 5 = 82 km / h
