All you have to do is find the LCD of the number of hours Mark and Frank uses to paint a room.
Mark - 3
Frank - 4
So list the numbers that are a result of a number and 3 and 4
(example: 4 x 1 = 4, 3 x 3 = 9)
3 - 3, 6, 9, 12, 15
4 - 4, 8, 12, 16
The list goes on and on but what we need to get is the LCD so it means it's the least number that 3 and 4 have in common.
3 and 4 both have 12 so The LCD of 3 and 4 is 12.
Another way of finding the LCD could be multiplying the numbers together, but it's not always gonna be the least number. Remember that LCD stands for Least Common Denominator.
How many hours would it take Mark and Frank to paint the room together at their respective rates?
The answer is - 12 hours
The product of 9 and the sum of three more than a number. 9(3+n)
Use tangent
tan=opposite/adjacent
tan(54)=x/150
multiply by 150
150×tan(54)=x
206.5=x (approximately)
Okay, so I just take 10 divided 2/7 to get 35 problems which is the total problems that Shelly has. Next, I already know that she did 10 problems, and she will just have 25 problems left.
Answer:
x=−y−3
Step-by-step explanation:
Step 1: Flip the equation.
−x−3=y
Step 2: Add 3 to both sides.
−x−3+3=y+3
−x=y+3
Step 3: Divide both sides by -1.
= 
x=−y−3
