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
Answer:
7b - 7
Step-by-step explanation:
You can use distributive property which is x (a + b) = x*a + x*b and x (a - b) = x*a - x*b. Therefore, the expression is 2*b + 2*4 + 5*b - 5*3 which is:
2b + 8 + 5b - 15, which is, if you combine like terms:
7b - 7

6 x 4 is the same as 6 divided by 1/4
the answer is :
1.5
Irrational. though 25 can be square rooted to find an integer, 35 cannot. the solution would be 0.84515425... and is irrational.
