3 9
_ * _
15 6

Compare diagonally to see if they the 2 numbers simplify.

Ex:

3 and 6 Simplify to 1 and 2 because they are both multiples of 3.

9 and 15 Simplify to 3 and 5 because they are both multiples of 3 as well.

Now our fractions are

1 3
_ * _
5 2

Now multiply across to get your final fraction/answer

3
_
10

Stefanie is painting her bedroom. She can paint 12 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one

aalyn [17]

Answer:

$31\frac{2}{3}$

Step-by-step explanation:

since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3

$12\frac{2}{3}$ ÷2= $6\frac{1}{3}$

$12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}$

$12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}$

Write quadratic function with zeros 3,6

kaheart [24]

Answer:

y=x^2-9x+18

Step-by-step explanation:

If x1=3 and x2=6, then the equation for the zeroes would be (x-3)(x-6)=0, which can then be expanded to x^2-9x+18=0, making the function y=x^2-9x+18

-18=-3t solve for for t

Harrizon [31]

Answer: 6 = t

Step-by-step explanation: To get <em>t</em> by itself since -3 is being multiplied by <em>t</em>, divide both sides of the equation by -3.

On the left, -18 divided by -3 is 6 and on the right, the -3's cancel.

So <em>6 = t</em>.
