Answer:

$x = 17$

Step-by-step explanation:

Since line m is parallel to line n, therefore:

$(6x + 5) + (5x - 12) = 180$ (consecutive interior angles are supplementary)

Solve for x

$6x + 5 + 5x - 12 = 180$

Add like terms

$11x - 7 = 180$

Add 7 to both sides

$11x - 7 + 7 = 180 + 7$

$11x = 187$

Divide both sides by 11

$\frac{11x}{11} = \frac{187}{11}$

$x = 17$

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
