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
∵
∴ m = 6
∵ m represents the number of miles that Ahmed runs each day
∴ Ahmed runs 6 miles each day
Answer:
Step-by-step explanation:
We are given that Hazel has an assortment of red , blue and green balls.
The number of red balls=The number of red balls
The number of green balls is more than the number of blue balls .
Let number of blue balls=x, Number of red balls=y, Number of green balls =z
Let total number of balls=w
Then number of red balls,y= Number of blue balls=x
According to question
x=y
z>x
The total number of balls,w= sum of all balls
substitute x<z
Both side divided by 3 then we get
.
Hazel will have number of blue balls is given by the equation
.
Where x= Number of blue balls
w=Total number of blue balls.
