So, first we must calculate 37/50 as a percentage. First -- we know that 60 is a factor of 100, so we multiply the denominator by 2 to give us 100 (100 is the maximum is a percentage (in this case)). We also multiple the numerator by 2 as "whatever you do to the denominator, you do to the numerator vice versus". This overall gives us 74/100 which is 74%. Therefore 37/50 is bigger than 73%. Hope this helped ;)
Answer:
755887578787-∵°
Step-by-step explanation:
We calculate the speed by dividing the distance over time:
s = d/t
So the distance described in the problem is always the same, A to B and B to A.
But we are told that;
7 = d/t
7 = 2d/(t + 2)
that is, the first equation say that at speed 7 km/h a distance d is walked in a time t
the second equation say that at a average speed of 7 (that is 8 on one way and 6 in the other: 8 + 6 = 14, half of it), twice the distance is walked in a time equal to the first time plus 2 minutes.
So we have a system of linear equations, 2 of them with two unknowns, we can solve that:
7 = d/t
7 = 2d/(t + 2<span>)
</span>lets simplify them:
7t = d
7(t + 2) = 2d
7t = 2d - 14
we substitute the first in the second:
<span>7t = 2d - 14
</span><span>7t = d
</span>so:
d = 2d - 14
d = 14
so the distance between A and B is 14 km
Step 1: Break off 1 from 9
8 3/3 - 2 1/3
Step 2: Subtract the whole numbers
8 - 2 = 6
Step 3: Combine fractions
3/3 - 1/3 = 2/3
6 + 2/3 = 6 2/3
Answer: 6 2/3 yd (D)
Either B or A?? Sorry if it’s wrong
