Answer:
Option A
Step-by-step explanation:
If you divide a negative number by a negative number, the answer will always be positive, so A must be the right answer
Ok so keep in mind, we are solving for x or z. We want to get it by itself.
So, with 6x= 5x+22, we need to subtract 5x from both sides of the = sign
So 6x - 5x = 1x.
Our new equation looks like 1x= 22
We still don't have x alone so we need to divide one on both sides of the =
Our new and final answer is x=22
Answer:
1. yes 2. no
Step-by-step explanation:
Hi there!
When x is equal to 5, 4x and 15+x have the same value because 4*5= 20 and 15+5 = 20.
4x and 15+x are not equivalent expressions because they cannot be simplified to create the same expression nor will they produce the same answer every time.
I hope this helps!
You can either convert -3 into a fraction, or convert -2/5 into a decimal so you can solve this.
If you decide to convert -3, into a fraction, it would be -3/1, and you'd have to multiply that by the reciprocal of -2/5.
So, you'd have -3/1(-5/2)=15/2, which can be simplified to 7 1/2.
If you decide to convert -2/5 into a decimal, you would get -0.4. You would then divide -3 by -0.4, which is equal to 7.5.
Both 7.5 and 7 1/2 are correct answers, and if you were to convert 7.5 into a fraction and 7 1/2 into a decimal, you would notice that they are the same number, but in different forms.
