Hello! $800 was the past amount for rent and now it's $900. 900 - 800 is 100. that's a $100 difference. In order to find the percent increase in the rent, we can write and sovle a proportion. It would be set up as change/original = x/100, where change is difference between two numbers and original is the previous price. It would be set up like this:
100/800 = x/100
Let's crossmultiply the values. 100 * 100 is 10,000. 800 * x is 800x. That makes 10,000 = 800x. Now, divide each side by 800 to isolate the x. 800x/800 cancels out. 10,000/800 is 12.5 or 12.5%. Let's check this by multiplying by 112.5%. 800 * 112.5% (1.125) is 900. That's what we're looking for! There. x = 12.5%. The percent increase is 12.5%.
3/5 squared in 9/25, 3*3/5*5 :)
Answer:
I'm not sure exactly what this means, but I think I have an idea.
Fraction form: -1x > -3/2x
Decimal form: -1x > -1.5x

Answer:
um, can you make that a bit clearer thanks! (:
Step-by-step explanation:
Solve for A
ab - ac = 2
First, you need to factorize
a(b - c) = 2
a= 2/(b -c)
