Do one hundred and twenty nine divided by three and you will get your answer
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:
We know that a tangent is a straight line that touches a curved surface or some curve at exactly one point. Or in short we may say that it just touches the curve. In geometry a chord is a straight line segment whose both end points lie on any curve.

Step-by-step explanation:
First divide 10.98 by 6 then 8.92 by 4 and subtract the two answers
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
