How do you know that 21 over 30 is greater than 2 over 3
Bond [772]
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.

Evaluate the expression when x=-5 <br> X^2 + 6x-9
d1i1m1o1n [39]

The value of the function f(x) = x² + 6x - 9 when x = -5 is  -14.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Given that:

f(x) = x² + 6x - 9

When x = -5:

f(-5) = (-5)² + 6(-5) - 9 = -14

The value of the function f(x) = x² + 6x - 9 when x = -5 is  -14.
