First, find common denominators
(3/4)(4/4) = 12/16
(3/8)(2/2) = 6/16
12/16k + 6/16k = 12
Simplify. Combine like terms
18/16k = 12
Isolate the k. Multiply 16/18 to both sides
(18/16)k(16/18) = 12 (16/18)
k = 12(16/18)
Multiply 12 with 16, then divide by 18
12 x 16 = 192
192/18 = 10.67 (rounded)
10.67 = 10 67/100 is your answer
hope this helps
Answer:
Step-by-step explanation:
-2 (-x +5y ) + 3 (2x - 6y)
Opening bracket
= 2x - 10y + 6x - 18y
= 8x - 28y
= 4(2x - 7y)
Answer:
f(2) = -6
Step-by-step explanation:
f(x) = 3x - 12
Let x =2
f(2) = 3*2 -12
= 6-12
= -6
