<h3><u>Let's start easy.</u></h3>

5\frac{2}{3} -\frac{1}{4}

<h3><u>Next up, let's make it a bit harder:</u></h3>

Ella is baking cookies to put in packages for a fundraiser. Ella has made 86 chocolate chip cookies and 42 sugar cookies.

Ella wants to create identical packages of cookies to sell, and she must use all of the cookies.

What is the greatest number of identical packages that Ella can make?

\frac{17}{3} -\frac{1}{4}

\frac{17x4-3x 4 }{12} \\\\\frac{68-12}{12} \\\\\frac{56}{12} =\frac{28}{6}=\frac{14}{3}

Multiply the denominators to make it one fraction.

Now for the numerator, you multiply the numerator of the the 1st fraction with the second fractions denominator. Then Multiply the 1st fractions denominator with the 2nd fractions numerator. Now with those two numbers you Subtract it. Whatever number you get is the numerator. So there is the fraction. You would just simplify it. (IF you want to add fractions instead of subtracting the numerators, you add the numerators. Like instead of 68-12 you would do 68+12

For which value(s) of x will the rational expression below equal zero? Check all that apply.
geniusboy [140]

Answer:

x = 5 and -2

Step-by-step explanation:

Given the function of x to be;

f(x) = (x-5)(x+2)/x+1

The value of x that will make the function zero can be calculated for by equating the given function to zero first to have;

If f(x) = 0, then;

(x-5)(x+2)/x+1 = 0

Cross multiplying;

(x-5)(x+2) = 0

(x-5) = 0 and x+2 = 0

x = 5 and x = -2

The value of x that will make the function zero is therefore 5 and -2
