<em>commutative property</em> a + b = b + a
... (-5 + 1/2 + 5) = ... (-5 + 5 + 1/2)
<em>inverse property of addition</em> a + (-a) = a - a = 0
... (-5 + 5 + 1/2) = ... (0 + 1/2)
<em>identity property of addition</em> a + 0 = 0 + a = a
... (0 + 1/2) = ... 1/2
<em>inverse property of multiplication</em> a/b · b/a = 1
37 · 2 · 1/2 = 37 · 2/1 · 1/2 = 37 · 1
<em>identity property of multiplication</em> a · 1 = 1 · a = a
37 · 1 = 37
The number of sports books is 13 books.
<h3>What is an equation?</h3>
A mathematical equation is the representation of a problem by the use of variables. Often times, an equation is formed from the factors that are in a problem.
We have to represented each of the books read with an algebraic term;
Let the number of mystery books be y
Let the number of sports books be x
Total number of books = 23
We know that;
x + y = 23
but y = 10
x = 23 - 10
x = 13 books

The answer would be 640. To find the number of how many copies are produced in 1 minute you have to write 80 divided by 5 which equals 16. Now you multiply 16 and the 40 minutes which gives you 640 copies.
You expect to sell between 80 to 100 hamburgers at the tournament ⚾️
1) Nuclear fission is the process of breaking of one element to two smaller ones; on the other hand, fusion involves the joining of two smaller elements to form a larger one. Both process release large amounts of energy; however, fusion is harder to initiate than fission. Fusion takes place naturally in stars.
2) The half life of Na-24 is 14.9 hours.
24Na11 → 24Mg12 + β
3) A nucleus consists of protons and neutrons and is held together by residual stron force.
The neutron is composed of one up quark and two down quarks
