Option A
<u>Answer:
</u>
The value of x in the equation 2(x - 3) + 5x = 5(2x + 6) is -12
<u>Solution:
</u>
From question given that
2(x - 3) + 5x = 5(2x + 6)
Open the brackets,
2x – 6 + 5x = 10x + 30
Rewrite the above equation,
2x + 5x – 6 = 10x + 30
On simplifying the above equation, we get
7x – 6 = 10x + 30
Now adding 6 on both sides,
7x – 6 + 6 =10x + 30 + 6
7x = 10x + 36
On subtracting 10x on both sides,
7x - 10x = 10x + 36 - 10x
-3x = 36
On dividing -3 on both sides,
x = -12
Hence on simplifying 2(x - 3) + 5x = 5(2x + 6) we get value of x is -12. Hence Option (A) is correct.
Okay, take for example:
1+2=3 is the same as 1=3-2
See how we changed the place of the 2. We can do that as long we change + to - and vica versa.
Let's see your example:
6+y=-8
We move the 6 on the other side of the expression with the opposite sign (it is a rule) and we get:
y=-8-6
y=-14
The answer to your question is
86+y=99
y=99-86
y=13
3 is the least common multiple for 6 and 21
Answer:
So you have 6 faces on a square, correct? And then you have 5 faces on a pyramid (including bottom). S, in how I am seeing it, you divide 6 by 5 to get 1.2. If this is incorrect I am sorry but that is what I see is correct.
Step-by-step explanation:
6/5=1.2
