Answer:
-8b - 5k + 9
Step-by-step explanation:
=(-4b + 15 - 7k) - (6 + 4b - 2k)
Taking away the brackets
=-4b + 15 - 7k - 6 - 4b + 2k
collecting like terms
=-4b - 4b - 7k + 2k + 15 - 6
= -8b - 5k + 11
Answer:
69.4 inches
Step-by-step explanation:
62 + 72 + 73 + 69 + 71 = 347
347 / 5 = 69.4
Option B: 5 is the value of f(3)
Explanation:
The equation of the piecewise function is given by
We need to find the value of 
The value of the function f can be determined when 
by identifying in which interval does the value of lie in the piecewise function.
Thus, lies in the interval 
, the function f is given by
Substituting in the function , we get,
Thus, the value of is 5.
Therefore, Option B is the correct answer.
Answer:
23
Step-by-step explanation:
we are given that angle NRQ is 78 degrees
we can see from the figure that the sum of the given angles is angle NRQ
so
(8x + 7) + (4x - 1) = 78
12x + 6 = 78
12x = 72
x = 6
Now, we have to find angle PRQ
replacing x with 6 in the equation of angle PRQ
PRQ = 4(6) - 1
PRQ = 23
Divide .98 by 3 1/2. 3 1/2 in decimal form is 3.5 so .98 ÷ 3.5 = .28
