Well we know there are 12 months in 1 year
So since she lived 9 already lets multiply that
12 x 9 = 108
so far she lived 108 months but wait! we still need to add 1/4 of a year
lets find out how many months 1/4 of a year is by dividing 12 and 4
sooo heres the math
12 ÷ 4 = 3
so she lived another 3 months.
Lets add on 108 and 3
108 + 3 = 111
so she lived 111 months her entire life
hope this helps
and dont forget 2
MARK ME BRAINLIEST! :P
I got 7 if you are trying to look for the value of x than you multiply the bottom by two to have the y's equal. It should be
3x+2y=25
12x-2y=80
Since the twos mark each other out it would be
3x=25
12x=80
You add the top and bottom so it becomes one like this
15x=105
Divide 15 on both sides and it should give you 7.
X=7

Step-by-step explanation:
Move the decimal to the left so there is one non-zero digit number left of the decimal point. This will be the exponent placed on 10
