Mathematics
1 answer:
Xelga [282]3 years ago
4 0

Answer:

r=-3

Step-by-step explanation:

−18=9r+9

Step 2: Flip the equation.

9r+9=−18

Step 3: Subtract 9 from both sides.

9r+9−9=−18−9

9r=−27

Step 4: Divide both sides by 9.

9r /9  =-27/9

I don't quite understand the LCD and the unlike denominators properly. May someone explain it, please.
Whitepunk [10]

Hey!

----------------------------------------------------------------------

LCD stands for Lowest Common Denominator.

----------------------------------------------------------------------

Explanation:

So let's say we have the equation 1/9 * 16/27

We want to find the LCD of both fractions. To find the LCD of both fractions find a the lowest common denominator in both fractions.

In this equation the lowest common denominator is 27 because 9 can go in 27 and 27 can go into itself. Se basically 27 is the lowest possibly common denominator both fractions can get to.

----------------------------------------------------------------------

Hope This Helped! Good Luck ;)

1. 7 + -10 = -3.
2. -3 + -8 = -11
3. 4 + -5 = -1
4. 2 + -6 = -4
(You basically need to add negative numbers to positive numbers in order to get negative numbers.)
