The LCM of 9 and 12 is 36.
I hope this helps, and have a good night and life! :D
This question belongs to greatest common factor.
Given, there are two types of trees.
25 elm trees and 20 oak trees.
Let's find the factors of 25 and 20
25 = 5 * 5
20 = 5* 4
The common factor between both the numbers is 5.
Hence, there should be 5 areas so that the trees can be planted equally.
Answer = 5 areas.
Answer:
3(x-6)+9=27
Step-by-step explanation:
1. Multiply 3 to x-6
3x-18+9=27
2. add -18 and 9
3x-9=27
3. add 9 to 27
3x=36
4. Divide 36 and 3
x=12
Answer:
125 cm³
Step-by-step explanation:
The cube has a side length of 5 cm.
Volume of a cube is given by; side × side × side
Since all the sides are equal then the volume is:
5cm × 5cm × 5cm = 125 cm³
Y = x + 5
y = -5x -1
so than you make y = y so x + 5 = -5x -1 result 6x = -6 so x = -6/6 so x = -1
and than you check it
y = - 1 +5 = 4
and
y = - 5 *(-1) -1 = 5 -1 = 4
so this mean that - 1 is the solution of the system sure
