Option 4 is correct.
Step-by-step explanation:
Answer:
So, the initial number of apples is 7.
Step-by-step explanation:
The number of apples of An, Binh, and Chi are the same. An gave away 17 apples, Chi gave away 19 apples, so now Chi's apples are 5 times higher than the total remaining apples of An and Binh. How many apples did each of you have at first? (Solve the above problem by equation or system of equations)
Let the initial numbers of apples is a.
An gave 17 apples
Chi gave 19 apples
So,
x - 19 = 5 (x - 17 + x)
x - 19 = 5 (2x - 17)
x - 19 = 10 x - 85
9 x = 66
x = 7

Answer:
Equilateral
Step-by-step explanation:
Since all sides are the same, the triangle is equilateral.
Answer:
7:11
Step-by-step explanation:
No of linemen = 7
No of running backs = 2
No of fullback = 1
No of quarterback =1
The total no of players on the team = 7+2+1+1 = 11
We need to find the ratio of the number of linemen to the total number of players on the team.
R = 7/11
or
R = 7:11
Hence, the required ratio is 7:11.
