Answer 7

it is the voodoo the idoo soo well

Answer 8

ever have a song stuck in your head that you cant quite recall the tune or the lyrics too? thats my life

Answer 9

best to work backwards, so final part says "is fifteen" so you know equation must be of the form\[... = 15\]
"three more" means add 3 to whatever you have, giving\[... + 3 = 15\]
"twice a number" - here you need to replace "a number" with a placeholder, lets call it x. So twice a number can be written as 2x, giving\[2x+3=15\]

Answer 10

good answer

Answer 11

Translating to Algebra you should read a little and translate a little.
Three more than means that you're adding 3 to something so you have
(something) +3
The question is what's 'something?'
The something is twice a number
(2x)+3
now comes the word that indicates you have an equation: the word 'is" which is the equal sign
(2x)+3=
finally we end with 15.
(2x)+3=15
done.

Note if it said 3 less than the
translation would be (2x)-3=15
In both cases the parentheses can be removed because the is no number
touching them on the left.
Final answer: 2x+3
