There you go... a. 10
If we add x to both sides, we get rid of the x on the right side which leaves us 1/2x + 2 = 7. (1/2=0.5)
Then if we substract 2 from both sides, we will get 1/2x = 5
If half of x = 5, then the whole of x = 10.
Answer:
D.) 4m, 11m, 9m
Step-by-step explanation:
According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side in order to form a triangle. Using the two shortest sides, you can find the sum and check to make sure it is larger than the third:
3m + 3m = 6m NOT greater than 6m
4m + 7m = 11m NOT greater than 12m
5m + 3m = 8m NOT greater than 9m
4m + 9m = 12m YES greater than 11m

Answer:
Logan's average swimming speed = 0.625 metres/second
Mia's average swimming speed0.833 metres/second
Step-by-step explanation:
Speed is obtained by dividing the distance covered by the time taken to cover such a distance.
<em>It will be necessary to make sure we are working in seconds for our time units.</em>
Logan's swimming time: 1/3 hours will be = 20 minutes = 1200 seconds
Mia's swimming time: 1/4 hours will be = 15 minutes = 900 seconds
Logan swam 750 metres. Logan's swimming speed will be
750metres / 1200 seconds = 0.625 metres/second
Mia's distance swam is 3/3 of Logan's. If we reduce the fraction 3/3 to its lowest term, we will have that it will be = 1/1.
1/1 X 750metres = 750 metres.
This means that Mia swam exactly the same distance as Logan.
Mia's swimming speed = 750 metres/ 900 seconds = 0.833 metres/second
