Hello there.

Question: <span>Jayden wants to solve the equation n + 67 = 81. He writes the equation n + 67 - 67 = 81 - 67 to find the value of n. Will Jayden get the correct answer using this equation?

Answer: n + 67 - 67.
In this part of the equation the 67 would cancel out.
Which leaves n = 81 - 67.
This would get the correct answer to the equation.
Solving the equation meant that he would have to subtract 67 from both sides.
Which he has done.
Solving the equation:
81 - 67 = 14
n = 14.

</span>Hope This Helps You!
Good Luck Studying ^-^

What number is 45% of 60, as well as 8 is 0.5% of what number?

Hi!

We can set up proportions to solve these.

1. $\frac{x}{60} \frac{45}{100}$

2. $\frac{8}{x} \frac{0.5}{100}$

Cross multiply to solve for x

1. 60 x 45 = 2700
2700/100 = 27

2. 8 x 100 = 800
800/0.5 = 1600
(Tip: dividing by 0.5 is the same as multiplying by 2)

The answers are
1. 27
And
2. 1600

Hope this helps! :)
