Picture?? I need to see what I’m working with
C?
Step-by-step explanation:
I haven't done this type of math in a minute so I'm sorry if it isn't the answer
We can easily figure out how fast the boat is moving per hour.
35 km / 7 hours = 5 km/h
We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer
5 km/h x 3 = 15 kilometers
Good luck!
Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x
