X/4 +x/5 -x/6=1
make the denominator the same:
15x/60 +12x/60 -10x/60=1
17x=60
x=60/17=3.53 hours
the second choice is the correct answer.

Just took the quiz :)
Answer:
B
Step-by-step explanation:
The GDP measures the market value of all goods and services produced in an economy (country or region) in a specific period of time. The GDP formula is:
GDP= Consumption (C)+ Investment (I)+ Government expenditure (G)+ (Exports - Imports) (Net exports)
Notice that if exports increase, GDP will increase too. Also, if investment increases GDP will increase. Notice that imports have a negative sign, then if they increase, GDP will decrease.
The answer is obtuse
a = 4
b = 28
c = 31
If a² + b² > c² - the angle is acute
If a² + b² < c² - the angle is obtuse
If a² + b² = c² - the angle is right
a² + b² = 4² + 28² = 16 + 784 = 800
c² = 31² = 961
800 < 900
a² + b² < c²
Therefore, the angle is obtuse
Answer:
145
Step-by-step explanation:
Adjacent interior angle = x
Sum of exterior angle and adjacent interior angle = 180
35 + x = 180
x = 180 - 35
x = 145
