Answer: The value of x is 8
Step-by-step explanation:
3(x + 5) − 3 = 52 − 2x
First open the bracket, and do multiplication
3x + 15 - 3 = 52 - 2x
3x + 12 = 52 -2x
Collect like terms, and make the whole expression equal to zero
3x + 12 - (52 - 2x) = 0
3x + 12 - 52 + 2x = 0
3x + 2x + 12 - 52 = 0
5x - 40 = 0
5x = 40
Divide both sides by 5
5x/5 = 40/5
x = 40/5
x = 8
Answer:
Step-by-step explanation:
x/13=10
We have to get rid of the 13. (the denominator)
How?
By multiplying 2 sides by 13
Remember the Rules of Maths:
1. Whatever you do to one side, you must do to the other.
2. Use the opposite operation.
So, we used Rule 2 to get rid of the 13.
Now:
x=10*13
(On the left side, the 13s cancel)
x=130
It is always a great idea to double-check
Does 130 divided by 13 equal 10?
Of course it does!
Have a great day!!
I hope everything is clear!
Answer:
3 < x < 17
Step-by-step explanation:
triangle inequality theorem: the sum of any two sides must be greater than the third
7 + 10 > x; x < 17
7 + x > 10; x > 3
A is the answer i believe
