Answer: x + 2/3(x)
Step-by-step explanation:
x = distance F walks to school
2/3(x) = distance T walks to school
Felipe walks first to school, then walks to Tim's house, so total distance Felipe walks: x + 2/3(x)
Answer: The value of x is -5 and the value of y is 5.
Explanation:
The slope of the line is 
and the point is (-2,5) from which the line line is passing.
If a line is passing through the point 
with slope m, the the equation of line is,
..... (1)
It is given that the point A(x,3) and B(-2,y) lies on the line. It means it satisfies the equation of the line.
Put y=3 in equation (1).
The value of x is -5.
Put x=-2.
The value of y is 5.
The arithmetic sequence is the first one.
Since the problem is quite vague because the number of
choice per question is not written here. I’ll just put for 4 choices and 5
choices each.
To compute for the 5 choices each:
Mean = np = 20 (1/5) = 4
Standard deviation = sqrt(npq) = sqrt (4*(4/5) = 1.79
To compute for the 4 choices each:
Mean = np = 20 (1/4) = 5
Standard deviation = sqrt(npq) = sqrt (5*(4/5) = 2
Can you make the answer clearer. I would be glad to help you. I just don't understand where it says "the sum of three numbers is 16 the sum of twice the first number"
