First you find the total, 40, then you find how many large or blue there are, 28 then you divide by the total to be 28/40 or 7/10
<h3>Answer: 5x-3</h3>
=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like
Then let's say we fill that box with the value 7. We would then have
If we put 3 in the box instead we'll have and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.
Answer:
Yes
Step-by-step explanation:
Plug in the numbers: 3≤3-2(0)
3≤3-0
3≤3
6x - 11 - 2x = -7
4x - 11 - = -7
4x = 11
X= 2
12- 11 -4 -3y = -7
-3 -3y = -7
-3y = -4
Y = -1
It should be 2,-1
