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!

Answer:
k = -111.34
Step-by-step explanation:
In this question, you will solve for k.
Solve:
k/3.8 + 57.6 = 28.3
Subtract 57.6 from both sides.
k/3.8 = -29.3
To get "k" by itself, multiply both sides by 3.8 to eliminate the fraction.
k = -111.34
-111.34 is the value of "k".
+17 bc you want to do the opposite so then it’s 17+10 which gets you x=27
