For the diagram below, form an equation and then solve it to calculate the value of x
Talja [164]
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80

A pizza dough recipe calls for 6 1/2 cups of flour. The recipe makes 37 1/2 ounces of dough. How many ounces of dough does 1 cup
NemiM [27]

Answer:

n = 5\frac{10}{13}

Step-by-step explanation:

Given

Call = 6\frac{1}{2} cups

Recipe = 37\frac{1}{2} ounce

Required

Number of ounces per cup (n)

To do this, we simply divide the Recipe by the call

So, we have:

n = \frac{Recipe}{Call}

n = 37\frac{1}{2} \div 6\frac{1}{2}

Express as improper fraction

n = \frac{75}{2} \div \frac{13}{2}

Rewrite as:

n = \frac{75}{2} * \frac{2}{13}

n = \frac{75}{13}

n = 5\frac{10}{13}
