(5y - 1) + (-2y + 4) = 5y - 1 - 2y + 4
= 5y - 2y - 1 + 4
= 3y + 3 [OPTION B]
Step-by-step explanation:
8.
Prime factorization of 48 is :
Option (3) is true.
9.
Prime factorization of 19 is:
19 = 19 × 1
Option (c) is correct.
(10).
Prime factorization of 924 is:
924 = 2 x 2 x 3 x 7 x 11
= 2² x 3¹ x 7¹ x 11¹
Hence, this is the required solution.
12, 20, 16, 10, 17, 9, 23, 13
1. add them all up
=120
divide by the number of numbers
120/8
=15
15 is the MAD
The answer is the number that 'Y' must be in order for
the equation to be true.
That number is called the 'solution' to the equation.
Here's one way to go about finding it:
You said that - 6y - 3 = 3 - 6y
Add 6y to each side: - 3 = 3
Let's stop right here.
Is there any value of 'Y' that can make -3 = 3 ?
I don't think so.
Your equation has NO SOLUTION.
There is NO NUMBER that you can write in place of 'y'
in your equation
- 6y - 3 = 3 - 6y
and have it work out to be true.
That's OK. There are lots of equations that have no solution.
