Step-by-step explanation:
<u>A</u><u>.</u><u> </u><u>Line up the decimals, then multiply as you would with whole numbers:</u>

<u>B. Line up the decimals, then add as you would with whole numbers:</u>
Note: These decimals aren't lined up exactly.



X= 45, you would place 15 into y's place, which would give you x-15= 30... then you would add 15 to both sides, which would give you x=45<span />
Okay, so as you may know the inside angles of a triangle always add up to 180! so you must first find x, so that means add up all equations to find x. your answer is 41
X=3/5
do you need an explanation?
Answer:
so first you do
12800*.12 which is 1536
so $1536 for 1 year
for 3 years multiply it by 3
1536*3=
$4608
so 4608+12800 =
17408 is totall
