BD is already given to you as bisected. AC must also be bisected. That means that 6x and 7x - 5 must the the same value. Then and only then will the figure be a parallelogram. (a four sided figure is a parallelogram if the 2 diagonals are bisected.
Equation
6x = 7x - 5 Subtract 6x from both sides
Solution
6x - 6x = 7x - 6x - 5 Simplify
0 = x - 5 Add 5 to both sides
5 = x - 5 + 5 Simplify
x = 5
Answer:
11. 9hrs
12. 5hrs 35min
13. 3hrs 48 min
Step-by-step explanation:
Makes it a bit easier if you convert to 24 hr time.
11. 10 - 19 is 9hrs
12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min
13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min
Answer:
1,5,6
Step-by-step explanation:
I suggest drawing a graph or simply using a calculator
The answers should be (5 - √ 41) / 2 and (5 + √ 41) / 2
