Answer:
Step-by-step explanation:
Hello
I believe there is an error in the question
we have two equations and need to find x and y
let s multiply by 8 so that we can get rid of the fractions
(1) becomes 2x+4y=5
(2) becomse 6x-4y=9
if we sum it gives
2x+4y+6x-4y=9+5
8x=14
x = 14/8 = 7/4
and then from the first equation
4y = 5 - 7/4
<=> 16y = 20-7 = 13
y = 13/16
the solutions is (7/4,13/16)
Answer:5 7th grade swimmers.
--------------------------------- =
16 swimmers
s 7th grade swimmers
----------------------------------
16 swimmers
4/10 = 2/5
When you divide both the numerator and denominator by 2 you will get a new fraction of 2/5. This fraction is in simplest form because you can't reduce it further.

Simple Interest is calculated using the formula: I=P*r*t
P=the principal (amount you start with)
r=percentage of interest earned
t= time in years
Area is square units, so the new area would be the scale factor squared:
Scale factor is 2, so the area would increase by 2^2 = 4
The answer is B.4
