Answer:
it's 256, the person above who answered is wrong
Step-by-step explanation:
What you have to do is add like terms. Once you do that you will come to an answer of -1
To solve this problem, identify the starting payment for video games that is given in the question. This is $10.
Since the company decides to increase the price by 300%, you have to multiply to get the new price.
Start by finding 100% on $10.
Since 100% of $10 is all that is there, that is another $10.
So now that you know a baseline for the increase in price, multiply that base by three to find the increase in price.
10 x 3 = 30
So, the company adds $30 to the price.
A simple addition problem gives you the new final price:
10 + 30 = 40
So, video games are now bought for $40 rather than $10.
I hope this helps! :)
Answer:
Yes, the formula describes y as a function of x
Step-by-step explanation:
The value of x in the given expression is; x = wz/y
<h3>How to change subject of formula?</h3>
We are given the expression;
w/x = y/z
Now, we want to find the value of x which means we want to make x the subject of the formula. Thus;
Multiply both sides of the given expression by x to get;
(w/x)*x = (y/z)*x
⇒ w = xy/z
Now, multiply both sides by z/y to get;
w(z/y) = (xy/z) * (z/y)
wz/y = x
Thus, the value of x in the given expression is;
x = wz/y
The correct question is;
If w/x = y/z, then what is the value of x
