Start by squaring the numbers on both sides to get rid of the square root on both the left and right sides to get:
x + 5 = 5^2 – x
x + 5 = 25 – x
Then rearrange to make x the subject.
x + 5 = 25 – x
2x + 5 = 25
2x = 20
x = 10
Answer:
B
Step-by-step explanation:
Yes, it is. The set of rational numbers is closed for all the four operations, so x+y, x-y, x*y and x/y are rational too. And it is easy to demonstrate. A rational number can be expressed as a fraction of two integers. So, x can be expressed as a/b and y as c/d. Hence x+y = a/b + c/d = (ad+bc)/bd, which, as fraction of two integers, is rational.
Well you 86 + 63 = 149 • 4 = 596 divide 2 = 298ft2
The question is a little hard to understand... let me see what i can do. I'll edit what i figure out on here. :) (PS) Did you reword the question? Do you think you could double check and make sure this is what the question looks like?
Started her day with a full bag of apples (?)
She needs 3 for an apple pie
She had 12 total (?)
Or maybe she needs 12 for a pie and now she has 3?
