For the first one, Rafiki is correct. Multiply each side by 3 to get x by itself and because 3 isn't negative, the sign stays the same.
For the second one, Duey is right because to get rid of a number in a equation subtract or add (depending on whether the number is positive or negative) from both sides.
For the last one I don't think aby of them are right.
Hope this helps!
Answer:
given equation,
3x+2y=1 ------------>(1)
x=5y+6 ------------>(2)
from (1) and(2),
3(5y+6)+2y=1
or, 15y+18+2y=1
or, 17y=1-18
or, 17y= -17
or, y= -17/17
:. y= -1 and x=5y+6=5×(-1)+6= -5+6=1
::: x= 1
:::y= -1 ans.
Your answer is B because it’s 6 times 3 times 4 and you add cubic because it’s volume.
The correct answer is: 3Explanation:
Instead of sharing the conventional tedious, method, let me share with you the simple trick here to solve these types of questions without using the calculator:
Given
It is essentially saying that WHAT power of 4(which is the base of log) gives us the value 64. You need to find the answer to that "WHAT."
Well
Hence the answer is "3".
Answer:
<h2>x = - 20</h2>
Step-by-step explanation:
<u>Move 3x to the other side of the equation</u>
<u>Move -14 to the right side of the equation.</u>
Multiply both sides by - 1
We have the final answer as
<h3>x = - 20</h3>
Hope this helps you
