What is the value of fraction 1 over 2 x4 + 5.2y, when x = 2 and y = 3
the answers on my test say 23.6, 24.6, 27.6 or 39.6 so idk what to put as my answer.
To find the value of the fraction 1 over 2 x 4 + 5.2y when x = 2 and y = 3, we need to substitute these values into the expression and perform the calculations step by step.
Let's start by substituting the given values into the expression:
1/2 * 4 + 5.2 * 3
Next, we'll perform the multiplication first:
1/2 * 4 = 2
5.2 * 3 = 15.6
Now we have:
2 + 15.6
Finally, we'll add the two numbers:
2 + 15.6 = 17.6
Therefore, the value of the fraction 1 over 2 x 4 + 5.2y when x = 2 and y = 3 is 17.6.
I know that it says that on your test but I got this answer, 19.6
what's the problem? Just plug in the numbers:
(2x^4)/(5*2y) = (2*2^4)/(5*2*3) = 32/30 = 16/15
Hard to say, though, given your probable typos. If I got it wrong, fix my mistake and then plug in the numbers as I did.
