Answer:

x≤-3      2 ≤x<7  

Step-by-step explanation:

(x^2+x-6) /(x-7) ≤0

Factor the numerator

(x+3)(x-2) / (x-7)≤0

Critical points are

X =-3  X =2  X=7

We need to check the values when

x≤3  -3 ≤ x≤2           2 ≤x<7   x>7  

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

x≤-3

(negative)(negative) / (negative) =   negative

-3 ≤x≤2    

(positive)(negative) / (negative) = positive  this range does not work

      2 ≤x<7  

(positive)(positive) / (negative) = negative

x>7

(positive)(positive) / (positive)

The value of expression 15/16 *9.1/5 is 69/8.

Given an expression being 15/16* 9.1/5.

We are required to solve the expression and find the value of the expression.

Expression is combination of numbers, symbols, coefficients, fractions, determinants, indeterminants but not mostly found in equal to form.

The expression is 15/16 *9.1/5.

9.1/5 is given in mixed fraction form so we have to first simplify it to a simple form.

Fraction is a combination of two numbers, one exists above the division sign and one below the division sign.

9.1/5=(5*9+1)/5=46/5

Now put the value of 9.1/5 in the given expression.

=15/16 * 46/5

=690/80

=69/8

Hence the value of expression 15/16 *9.1/5 is 69/8.

Wich is greater 42% or 0.44
kakasveta [241]
Since percent means 'over 100', you can put 42 over 100: \frac{42}{100} = .42. Since .42 is less than .44, that means that .44 is your answer.
