Answer:
Step-by-step explanation:
392/275 as a fraction
X, y - the numbers
The sum of the two numbers is 9.
If one number is subtracted from the other, the result is 3.
Solve the system of equations:
The numbers are 6 and 3.
The <em><u>correct answer</u></em> is:
Any real number for x except 5, and any real number for y.
Explanation:
A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value. This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.
This means that 5 cannot be used for x in the other ordered pair.
Since there is no restriction on y in order to be a function, y can be any real number.
Answer
Front yard is 20 square root 5 back yard and height is 40 square root 5
Step-by-step explanation:
1. set up A=1/2 H(b1+b2)
2. 6000=1/2 2x (2x+x)
3. 12000=6x^2
4.2000 = x^2
5. x=20 square root 5
The problem deals with fractions comparison, lets do it:
21/30 > 2/3
we begin solving:
21 > (2/3)*30
21 > 2*10
<span>21 > 20
</span>therefore the proposed inequality is true, <span>21/30 > 2/3
You can solve as well getting same denominator for both fractions and comparing directly, in this case we need to get 2/3 to be divided by 30:
2/3 = (10/10)(2/3) = 20/30
So we have:
</span><span>21/30 > 2/3
</span>which is equal to:
<span>21/30 > 20/30
</span>and we compare directly because both fractions are divided by the same number, and we can see that the inequality is true.
