Answer:
The constant of variation is 5
Step-by-step explanation:
We know direct variation is of the form
y = kx
We know y =25 and x=5
25 = k*5
Divide each side by 5
25/5 = 5k/5
5 = k
The answer is w + 4 > -12
3 = X/2 + 2
1 = X/2
2 = X
Jan had 2 pencils to start off with. She gave half (1 pencil) to Talia. Her brother gave her 2, which means she ends up with 3.

Now multiple the coefficients and add the exponents with common bases

Now write your final expression
