There are a total of 135 seats, 118 front handlebars and 269 wheels. How many bicycles, tandem bicycles, and tricycles in the wh
Degger [83]
118 handle bars tells us that there's 118 bikes

if all 118 bikes were regular bikes
118*2 = 236
we would be 33 wheels short

118*1 = 118
we would be 17 seats short

----

if 101 of the bikes are regular and 17 are tandem
101*1 = 101
17*2 = 34
we would have the right amount of seats

101*2 = 202
17*2 = 34
202 + 34 = 236
we would be 33 wheels short.

----

if 17 bikes are tandem, 33 are tricycle, and 68 are regular
17*2 = 34
33*3 = 99
68*2 = 136
we would have the right amount of wheels

---

Answer:
There are 68 bicycles, 17 tandem bicycles, and 33 tricycles.

This question isn't hard, it just takes longer since it's based off of guess and check.

By how many degrees did the direction of the boat change
gulaghasi [49]

Answer:

The boat turned <u>39°</u> degrees when it made its first turn.

Step-by-step explanation:

The question is as following:

A boat traveled north for 28 miles, then tuned x° south west and traveled for 25 miles before stopping. When it stopped, the boat was 18 miles from its starting point.

By how many degrees did the direction of the boat change when it made its first turn? Round to the nearest degree.

===================================================

See the attached figure which represent explanation of the problem.

The boat start from point A to point B then stopped at point C

AB = 28 miles, BC = 25 miles and AC = 18 miles.

It is required to find the angle x

By applying the cosine Rule:

AC² = AB² + BC² - 2 * AB * BC * cos x

18² = 28² + 25² - 2 * 28 * 25 * cos x

2 * 28 * 25 * cos x = 28² + 25² - 18²

1400 cos x = 1085

Cos x = 1085/1400 = 0.775

x = Cos⁻¹ 0.775 = 39.2° = 39° to the nearest degree.

So, the boat turned <u>39°</u> degrees when it made its first turn.

Are -4 ( x - 6) and -4 • x - 4 • 6 equivalent
tekilochka [14]

Answer:

 no

Step-by-step explanation:

Lets solve the first half.

-4 ( x - 6) = -4x + 24

Second one:

-4 times x - 4 times  6 = -4x -24

Now compare.....Not the same right??

So your answer is:  no

Hope this helps :)
