It’s $13.75=3x-$2.50 -> $11.25=3x -> $3.75=x
X=g
It is B because an equilateral triangle has all 3 sides that are equal
We know that
<span>It takes Jonas ---------> 7 1/4 minutes to run the mile
7 1/4-------> (7*4+1)/4------> 29/4 minutes
</span>It takes Mario ---------> 8 5/12 minutes to run the mile
8 5/12-------> (8*12+5)/12------> 101/12 minutes
multiply (29/4) by (3/3)-------> 87/12
[101/12]-[87/12]------> 14/12 -------> 7/6 -------> 1 1/6 minutes
the answer is
1 1/6 minutes
