Answer:
96cm
Step-by-step explanation:
If the width is x then length is 2x
so,
x+x+2x+2x=288
6x=288
x=48
length is 48cm
-9 +a =-2 Distribute that negative into the a
a=-2 + 9 Then you do the opposite sign
which mans since the nine was negative you would add it to the negative two
your answer is
a=7
At my favorite drugstore, comic books used to cost 10¢ .
(It wasn't yesterday, or even last week. In fact, the drugstore
was burned to the ground during the riots in 1964, and never
rebuilt. But I digress.)
Normally, my parents only let me buy one comic book at a time.
But before I left for summer camp, I could empty my little piggy
and spend it ALL on comic books, all at the same time ! That
was as much fun as the whole 2 weeks at camp !
I emptied my little pig. I had 67¢ in there. I headed for the
drugstore. For the whole rest of the afternoon, I stood at the
magazine rack, carefully deciding on my selections.
How many comic books did I buy ?
What was the remainder ? (How much money did I have left ?)
x = -52 4/17
