Answer:

The answer is 11

Step-by-step explanation:

To solve the expression we must use order of operations following the memotecnic rule PEDMAS that states the order of operations. First solve parenthesis, then exponents, then divisions and multiplications from left to right and finally additions and subtractions from left to right . Following this rule we have:

30-2(7+2)-1

First parenthesis

30-2*(9)-1

There are no exponents. There are no divisions so we do multiplications first

30 -18 -1

There are no additions we only do the remaining subtractiosn form left to right

30-18-1= 12-1= 11

Sarah's craft project uses pieces of yarn that are 1/8 yard long. She has a piece of yarn that is 3 yards long. How many 1/8 yar

Verdich [7]

If she used all of her yarn, she'd have 24 pieces. If she wanted 1.25 left, she'd have ten less because 24 • .125 = 8, and 1/4 of eight = 2, and 2 + 8 = 10.

So she'd have 14 pieces.

I believe the answer is 4x + 8. you multiply 4 by x which makes 4x. Than you multiply 4 by 2, making 8.
