First the common denominator has to be 6. So to get to 6 you multiply the 2 by 3 and the numerator by 3 giving 3 over 6 then you multiply 3 times 2 to get to 6 so the following fraction is 2 over 6. So when u add the two together it gives you 5 6ths
Answer:
-11/10 or -1.1
Step-by-step explanation:
To start, let's get rid of those pesky decimals by multiplying everything by 2. Then we get 9 + 20r = -13. Now, let's isolate the r by subtracting 9 from both sides to get 20r = -22. Finally, we need to divide everything by 20 to get r = -11/10 or -1.1.
Answer:
-1
Step-by-step explanation:
(0, 0) and (3, 3)
To find slope:
3-0/3-0 = 3/3 = 1
Since it's looking for the perpendicular slope, you just do the opposite of 1.
Which is -1.
L is 0 because it cancels itself out
Answer:
x = 10
Step-by-step explanation:
Step 1: Write equation
3x - 8 = 22
Step 2: Add 8 to both sides
3x = 30
Step 3: Divide both sides by 3
x = 10
