Answer:
the answer is f(x) = x + 5 ( the first option)
Step-by-step explanation:
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!
It would equal 29$ dollars because you divide 20 and 3, and with that answer you multiply by 4.35 :)
Answer:
Un excursionista camina por un prado llano, observando una montaña a
lo lejos. Mide que el ángulo de elevación entre el suelo
y la cima de la montaña es de 25 grados. Camina 5 millas y luego
