Answer:
The length of the loop is approximately 49.58 km.
Step-by-step explanation:
Given:
Time required to ride bicycle in loop = 2 hours and 30 mins
Now we know that;
60 mins = 1 hour
30 mins =0.5 hour
so 2 hour and 30 mins = 
∴ Time required to ride bicycle in loop = 2.5 hrs
Let the speed at which she is riding the bicycle be 's'.
and let Total distance of the loop be 'd'
Now we know that;
Distance is given by speed multiplied by time.
framing in equation form we get;
Now Given:
If she increase the speed by 1 km/hr, it would reduce her time around the loop by 7 minutes.
Hence we can say;
Speed =
Also time will be reduce to 7 mins.
7 mins =0.12 hrs
Now time = 2.5-0.12 =2.38
Again Distance is given by speed multiplied by time.
framing in equation form we get;
Now distance is same for both so we will calculate the speed by equating the equations.
Now Speed = 19.83 km/hr
Length of the loop (d) = 
Hence the length of the loop is approximately 49.58 km.

Answer:
A: 7 + 3 (negative 4) (2)
Step-by-step explanation:
Just as a rule of thumb, whenever you multiply or divide one negative number and one positive number, the outcome is always negative. However, whenever you multiply or divide two negative numbers OR two positive numbers, the outcome is always positive.
Now, let's first convert all these words into simple mathematical expressions and then solve them:
A) "7 + 3 (negative 4) (2)" = 7 + 3 * (-4) * 2 = 7 + (-24) = -17
B) "Negative 2 Left-bracket 12 divided by (negative 3) Right-bracket" =
-2 * [12/(-3)] = -2 * (-4) = 8
C) "(15 minus 7) minus (9 divided by 3)" = (15 - 7) - (9/3) = 8 - 3 = 5
D) "Negative 5 Left-bracket 7 + (negative 14) Right-bracket minus 30" =
-5 * [7 + (-14)] - 30 = -5 * (-7) - 30 = 35 - 30 = 5
The only expression that produces a negative value is the first one, A.
Hope this helps!
