Answer:

x = 25

Step-by-step explanation:

Both angles are supplementary and will add up to 180°

5x - 5 + 2x + 10 = 180

collect like terms

5x + 2x +10 -5 = 180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175/7

x=25

3/4 is equal to how many 84ths? Explain please!
frutty [35]
It is just asking for you to convert 3/4 in 84ths. This means it wants the denominator to be 84. So multiply both the top and bottom by what gets you 84. In this case, multiply both by 21. So 3/4•(21/21)=63/84

Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.

<h3>How to form equation and solve ?</h3>

The fundraiser only have 3 prices for books which are $2, $5 and $10.

There were 6 more $5 books sold than $10 books sold.

Let

x = number of $10 book sold

Therefore,

number of  $5 books sold = x + 6

There are 8 more $2 book sold than $10 book sold. Therefore,

number of  $2 books sold = x + 8

A total of $250 was raised.

Therefore, the total amount sold forms the following equation:

10x + 5(x + 6) + 2(x + 8) = 250

10x + 5x + 30 + 2x + 16 = 250

17x = 250 - 30 - 16

17x  = 204

x = 204 / 17

x = 12
