The Least Common Multiple (LCM) of 3 and 12 is 12 so any number which is divisible by 12 is common multiple of them like:
12, 24, 36, 48, 60....
Hope this helps!
Suppose x quarts of the 50% solution
0.5x+0.2*20=0.4(x+20)
0.5x+4=0.4x+8
0.1x=4
x=40
Answer:
7d-5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length.
The perimeter of a regular pentagon is given by
P = 5s where s is the side length
35d -25 = 5s
Divide each side by 5
(35d-25)/5 = 5s/5
7d-5 =s
Each one of the sides is equal to 7d-5
Answer:
y=7/5x+26/5 and y=-5/7x+66/7
Step-by-step explanation:
if it's parallel, it needs to have the same slope, so the equation is y=7/5x+26/5. the perpendicular line is y=-5/7x+66/7.
