Answer:
42/37
Step-by-step explanation:
42/n - 35 = 2 Multiply everything by 7 to get rid of the fraction
42 - 35n = 2n Multiply everything by n
42 = 37n Move 35n to the right side
42/37 = n Divide by 37

8/100 * 125 =
(125 * 8)/100 =
1000/100 =
10
$125 + $10 = $135
Answer: B. $135.00
Ok so first we need to write a fraction.
75 percent/45 mins
then we convert that into a unit rate
1.67 percent/1 min
so, now that we have the unit rate, we know exactly how fast she is moving.
Now, we divide 25 by 1.67 because 25% is the distance between the completion of the gate and current state of the gate.
So we get 14.97, which we can safely round up to 15.
It will take her 15 mins more to finish the gate, and it has already taken 45, so 45+15=60
60 MINS TOTAL/ 1 HOUR
