11.(A-CED.A.1 ) Write and solve the equation
Black_prince [1.1K]

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

∵ \frac{3m}{3}=\frac{18}{3}

∴ m = 6

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

∴ Ahmed runs 6 miles each day
