Find the least common denominator of 2 and 3, which is 6. Because you had to multiply 2 by 3 to get 6, you have to multiply 1 by 3, you then get 3/6. Because you had to multiply 3 by 2 to get 6, you have to multiply 1 by 2, you then get 2/6. Now, you can subtract 3/6 - 2/6, which equals 1/6. Hope this helps!
Answer:
x = 1/7(k+12)
Step-by-step explanation:
7x - 12 = k
Add 12 to each side
7x - 12+12 = k+12
7x = k+12
Divide each side by 7
7x/7 = (k+12)/7
x = 1/7(k+12)
Answer:

Step-by-step explanation:
.......,??????
Remmeber, you can do anything to an equation as long as you do it to both sides
for inequalities, if you multiply or divide both sides by a negive, flip the direction of the inequality sign
pemdas always applies
but also the commutative property and assiociative property
so
2(5y+13)-6<20
add 6 both sides
2(5y+13)<26
divide both sides by 2 (easier that distributing)
5y+13<13
minus 13 both sides
5y<0
y<0 is the solution
20 = 40e^-0.1446t
e^-0.1446t = 0.5
t = ln 0.5 / -0.1446
t = 4.8 days
