16= -5+z/4
a. 69
b. -1
c. 9
d. 59

Answers

Answer 1
Answer: If you would like to solve the equation 16 = (- 5 + z) / 4, you can do this using the following steps:

16 = (- 5 + z) / 4       /*4
16 * 4 = - 5 + z
16 * 4 + 5 = z
 z = 69

The correct result would be a. 69.
Answer 2
Answer: 16 = (-5+z)/(4)

Multiply both sides by 4

16* 4 = (-5+z)/(4) * 4

64 = -5+z

Rearrange the terms

64 = z - 5

Add 5 on both sides.

64 + 5 = z - 5 + 5

\boxed{\bf{z = 69}}


Your final answer is a. 69.

Ana Participated in each charity walk she raise $.25 and each 1/2 That she walked the first day and I walked 11 miles a second day she walked 14 miles how much money did she raise

Answers

Question:

Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.The first day Ana walked 11 miles.The second day, she walked 14 miles.How much money did Ana raised?

Answer:

Ana raised $ 12.5

Solution:

From given question,

First day walk = 11 miles

Second day walk = 14 miles

Let us first calculate the total distance she walked

Total distance = first day walk + second day walk

Total distance = 11 + 14 = 25 miles

Thus she walked for 25 miles

Given that,

She raised $0.25 for each 1/2 mile that she walked

(1)/(2) \text{ mile} = 0.25 \text{ dollars }

Therefore, for 1 mile we get,

(1)/(2) * 2 \text{ mile} = 0.25 * 2 \text{ dollars }\n\n1 \text{ mile } = 0.5 \text{ dollars }

Now calculate for 25 miles

25 \text{ mile } = 25 * 0.5 = 12.5 \text{ dollars }

Thus she raised $ 12.5

Find the range of f(x) = 5 - |x - 4|.

Answers

Y is less than or equal to 5.

Final answer:

The range of the absolute value function f(x) = 5 - |x - 4| is (-∞ , 5] because the function will always be less than or equal to 5, but there's no lower limit as the function will decrease indefinitely as |x - 4| increases.

Explanation:

The function given is f(x) = 5 - |x - 4|, which represents an absolute value function. The range of a function refers to the possible values of f(x) or y in the function. In general, the absolute value function has a range of all non-negative numbers. However, because the function is subtracted from 5, the values of this particular function will decrease as x moves away from 4, in either direction.

Therefore, the maximum value of the function occurs when the absolute value equals to zero (i.e., x = 4), then f(x) = 5 - 0 = 5. As you move away from 4, the absolute value increases and thus subtracts more from 5, making f(x) smaller. So, f(x) will always be less than or equal to 5, but there is no lower limit, as the function will continue to decrease indefinitely as |x - 4| increases. Hence the range of the function f(x) = 5 - |x - 4| is (-∞ , 5].

If a man travels p hours at an average rate of q miles per hour, and then r hours at an average rate of s miles per hour, what is his overall average rate of speed?

Answers

Total miles traveled in p hours = p*q miles and 
Total miles traveled in r hours = r*s miles
so, average rate of speed = total miles traveled / number of hours
                                     =[{(p*q)+(r*s)} / (p+r)] miles per hour
