\dfrac{x^2-7x-18}{x^2+8x+12}=\dfrac{x^2+2x-9x-18}{x^2+6x+2x+12}=\dfrac{x(x+2)-9(x+2)}{x(x+6)+2(x+6)}\\\\=\dfrac{(x+2)(x-9)}{(x+6)(x+2)}=\dfrac{x-9}{x+6}

A recipe for bran muffins calls for 2 1/2 cups of bran flakes. The recipe yields 9 muffins. How much bran flakes should be used
kolbaska11 [484]

10/3 bran flakes can make a dozen muffins

A recipe requires 2 1/2 cups of bran flakes

The recipe can make 9 muffins

Let's calculate the amount of bran flakes it will take to make 1 muffin

5/2 = 9

x= 1

cross multiply

9x= 5/2

x= 5/18

A dozen is 12, the number of bran flakes to make a dozen can be calculated as follows

5/18= 1

y= 12

cross multiply

y= 5/18 × 12

y= 10/3

Hence it will take 10/3 to make a dozen muffins

1b) Answer the following: *<br> If arc WX = 40' and arc Y Z = 92, find m23.
spin [16.1K]

Answer:

m<3 = 66°

Step-by-step explanation:

<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.

The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.

Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:

m<3 = ½(40 + 92)

m<3 = ½(132)

m<3 = 66°

A store is having a closing sale. All items in the store are 35% off. Samantha found a jacket she wants to buy with an original
laila [671]

Answer:

The final price paid by Samantha is 55.25 $

Step-by-step explanation:

In order to find out the final price of the jacket for Samantha we need to calculate how much 35% of 85 $ is and subtract the original price by it. So we have:

price of discount = 85*(35%) = 85*(35/100) = 85*(0.35) = 29.75 $

Now we can compute the final price by subtracting the original price by the price of discount. So we have:

final price = original price - price of discount = 85 - 29.75 = 55.25 $
