Answer:
9.5 feet
Step-by-step explanation:
15.5-6=9.5
A^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
-400. -400
b^2=√441
b=21
Answer:
5 hours
Step-by-step explanation:
The total cost is the fee plus the hours* hourly cost
450 = 200+50*h where h is the hours
Subtract 200 from each side
450-200 = 200-200 +50h
250 = 50h
Divide each side by 50
250/50 = 50h/50
5 = h
5 hours
1/7x
Factorize the numbers (4 and 28) as they have a common factor of 4 so you can simplify it to 1/7. Cancel out the 3 in the x (numerator) from the denominator and you will have x^1 remaining in the denominator. That is also the same as x, therefore making it 1/(7x)
It’s the second one. Hope this helped
