The LCM is 540 because 54X10=540 which 20 goes into
I am pretty sure it would be -2. Hope this helps. :)
Answer:
k = 11
Step-by-step explanation:
f(x)=3x+k,
We know the input is -1 so replace x with -1 and the output is 8 so replace f(x) with 9
8 = 3(-1) +k
8 = -3+k
Add 3 to each side
8+3 = -3+3+k
11= k
Okay, so how to do it, so the parentheses around the two doesn’t matter, you can times 4.16 and .2 together to get .832, it is fairly easily.
How I got it: 4.16 is on the top of .2, the decimals line up, you add a zero behind the 2 to make it a 20, now you just Times 4.16 by .20 to get .832
