In 36 days will the science and math teachers both give tests on the same day again.
<u>Step-by-step explanation:</u>
Here we have , The 6th grade science teacher gives a test every 12 days and the math teacher gives a test every 9 days. Today, both the science and math are giving tests. We need to find In how many days will the science and math teachers both give tests on the same day again . Let's find out:
It's given that science teacher gives a test every 12 days and the math teacher gives a test every 9 days . In order to find the number of days after which they'll give test at same day , we will find LCM of 12 & 9 . i.e.
⇒
and ,
⇒ 
Hence , LCM of 12 and 9 is 36 . Therefore , In 36 days will the science and math teachers both give tests on the same day again.
Answer:
C. 4i
Step-by-step explanation:
√-1 is imaginary number i
Step 1: Write expression
√-16
Step 2: Factor
√-1 · √16
Step 3: Simplify
i · 4
4i
4x^2+6x=12
16x+6x=12
22x=12
x=12/22 or 0.55
The decimal is rounded to the nearest hundreth

Answer:
x=11
Step-by-step explanation:
(x-3)/2=(x+1)/3
multiply (x-3)(3) and 2(x+1)
3(x-3)=2(x+1)
3x-9=2x+2
Get the variables on one side and numbers on another
3x-2x=3+9
x=11
