26.04 I think I am not really sure what the question is asking
Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657
B = block p = park
2b + p = 10 min 2 runs around the block takes 10 minutes
2b + 3p = 22 min 2 runs around the block plus 3 runs around the park takes 22 minutes
To solve, I will use substitution. First, I will divide the first equation by 2 to get b by itself and subtract p from both sides to get b by itself. Then, substitute 5 - 1/2p in for b in the second equation because they have equal values. Then, subtract 10 from both sides to eliminate it. Divide by 2 to both sides to get 'p' by itself.
2b + p = 10 min ---------→b + 1/2p = 5 ----------→ b = 5 - 1/2p
2(5 - 1/2p) + 3p = 22 ---------→ 10 -p + 3p = 22 --------→ 10 + 2p = 22
10 + 3p = 22 ----------→ 2p = 12
2p = 12 -------------→ p = 6
It takes 6 minutes to jog around the park
Hope this helps!
Terminal digit filing is a filing system that
works by means of the last two numbers on files to consolidate them. While
middle digit filling uses a tripartite number, using the first part of the
number for the second sort, middle part for the initial sort, and the third portion
for the final sort. One way they are similar is that the two evade working with
large numbers and overpowers the difficulties of crowding at the end of the
storage.
It would be c because fe is a radius ba is a chord and ec isnt a line
