Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.
The answer is 17
This is because 1 + 2 must equal 180 as they are in a straight line.
So 4x + 2 + 110 = 180
Take away 110 from both sides
4x + 2 = 70
Take away 2 from both sides to get 4x = 68. Finally, divide both sides by 4 to get x = 17
49 pieces because 7/8 is equivalent to 49/56. If each piece is 1/56, then there 49 of them.
If you want to multiply a decimal by a whole number,just ignore the decimal point and multiply by normal.
