Ahmad runs m miles each day. Ali runs twice as many miles as Ahmad. Altogether, they run 18 miles each day. How many miles does Ahmad run each day?

Respuesta :

Answer:

Ahmed runs 6 miles each day

Step-by-step explanation:

Ahmad runs m miles each day

∵  Ali runs twice as many miles as Ahmad

→ That means Ali runs 2 × m miles each day

Ali runs 2m miles each day

∵ Altogether, they run 18 miles each day

→ Add m and 2m, then equate the sum by 18

m + 2m = 18

∴ 3m = 18

→ Divide both sides by 3 to find m

∵ [tex]\frac{3m}{3}=\frac{18}{3}[/tex]

m = 6

∵ m represents the number of miles that Ahmed runs each day

Ahmed runs 6 miles each day
