It’s option D.) I did a quiz on this !
Step-by-step explanation:
let 1 pound of nail = x
so, the carved out waste nail will be = 12x
total nails = 13x
so the equation is =
13x - 12x = x
OR
x + 12x = 13x
Or
13x - x = 12x
26 is the number of the parallelograms that fall into the category A U B. In this universal set, you must likely to find 26 parallelograms that fall into the category A U B. With 4 congruent sides and four congruent angles in set A and B we can see 26 parallelograms that fall into the category A U B.
So $2100 = 1+3/4 of her original raise.
Remember that 1 = 4/4, so in total it is 7/4 of her original pay (4/4+3/4). Let's find out what 1/4 is equal to.
If $2100=7/4 then 1/4=$300. Therefore 4/4 (or 1, her original pay) is 4 times $300, which is $1200.
