Answer:
Because the sum of the interior angles of a triangle is 180,
X=180-(65+35)
X=180-100=80
Answer:
Step-by-step explanation:
domain (ur x values) = -3,-1,1,2
range (ur y values) = -3,1,2,4
do not have to write them more then once
answer is C
Answer:
3,000
Step-by-step explanation:
Just multiply every decagram by 1,000
Answer:
Step-by-step explanation:
- Let the speed of the boat be x
- Speed against the current in the river is x - 2
<u>Time in the river:</u>
<u>Time in the lake:</u>
<u>The difference:</u>
Solve for x to find the speed of the boat
<u>Multiply both sides by x(x - 2) to clear the fraction:</u>
- 6x = 15(x - 2) - x(x - 2)
- 6x = 15x - 30 - x² + 2x
- x² - 11x + 30 = 0
- (x - 5)(x - 6) =0
- x -5 = 0, x - 6 = 0
- x = 5 km/h, x = 6 km/h
If you convert the fractions to improper, you get 9/2 times 7/4. you can then just multiply the tops and bottoms and simplify! hope this helps
