Answer:
8 =x
Step-by-step explanation:
2x+9=3x+1
Subtract 2x from each side
2x-2x+9=3x-2x+1
9 = x+1
Subtract 1 from each side
9-1 = x+1-1
8 =x
It's a right triangle problem, and pretty obviously a multiple of the only Pythagorean Triple most folks know, 3²+4²=5². In this case we multiply the lengths by three getting
9²+12²=15²
If we place the 15 foot ladder 9 feet from the house it will hit the house at height 12 feet.
Answer: 9 feet
Answer:
1.8 mph
Step-by-step explanation:
Speed of the steamer in still water is 18 mph.
Speed of the current = x mph.
1. The steamer going downstream traveled the distance between two ports in 3 hours. Traveling downstream the current "helps" the steamer, then the speed is 18 + x mph.
The distance traveled downstream = 3(18 + x) miles.
2. The steamer going upstream traveled the distance between two ports in 3 hours 40 minutes that is
hours. Traveling upstream the current "interferes" the steamer, then the speed is 18 - x mph.
The distance traveled upstream
miles.
3. The distances are the same, so

Solve this equation:

Answer: y = 24
Step-by-step explanation:
you need the pythagorean theorem(a^2 + b^2 = c^2)
so we have the hypotenuse so we plug in what we knowwhich is:
10^2 + b^2 = 26^2 -> 100 + b^2 = 676
then solve for b^2
b^2 = 576 ->
= 24
