When you write an equation, it tells you, that you know what the math problem is and your steps of solving. For example if the math problem was that:

Trina invited 9 girls and 10 boys to her birthday. 2 girls didn't come and 1 boy didn't come. What is the total amount of people that came to Trina's birthday party.

Equation: 9+10-2-1=?

Answer would be: 9+10=19
19-4=15.

So only 15 people came to Trina's birthday party!

:) Hope I helped!

What’s is x=5y for y

Margarita [4]

Answer:

$y=\frac{x}{5}$

Step-by-step explanation:

$\frac{x = 5y}{5}$

For the y to cancel out, you would have to divide y by 5. Whenever you do one thing to a side, you have to do the same on the other side. Once you do so, you'll get : $\frac{x}{5}$

Hope this helps!!

Who walks at a faster rate: Jake who walks 60 feet in 10 seconds or Lucy who takes 5 seconds to walk 25 feet?

My name is Ann [436]

Answer:

Jake

Step-by-step explanation:

The average rate of change is distance divided by time. You want both of their rates in feet per second. 60 feet divided by 10 seconds is 6 feet per second. 25 feet divided by 5 seconds is 5 feet per second. 6>5
