Answer: 13 is a rational number
Step-by-step explanation: By definition, a rational number is a number q that can be written as a fraction in the form q=a/b where a and b are integers and b≠0. So, 1/3 is rational because it is exactly what you get when you divide one integer by another.
Answer:
the student solved the equation incorrectly because the original equation has one solution
Step-by-step explanation:
1/8(40x + 16) = 9x − 7(2x − 1) − 5
<em>use the distributive property a(b + c) = ab + ac</em>
(1/8)(40x) + (1/8)(16) = 9x + (-7)(2x) + (-7)(-1)
5x +2 = 9x − 14x + 7 − 5 <em>combine like terms</em>
5x + 2 = (9x - 14x) + (7 - 5)
<em>here the student make mistake 9x - 14x = 5x</em>
5x+2=-5x+2 <em>add 5x to both sides and subtract 2 from both sides</em>
5x + 5x + 2 - 2 = -5x + 5x + 2 - 2
10x = 0 <em>divide both sides by 10</em>
10x/10 = 0/10
x = 0
24.5% is the same as 0.245 (decimal) and 24.5/100 (fraction). 24.5/100 is 245/1000, which is simplified by dividing numerator/denominator by 5 to get 49/200.
