Your answer is the last one, h=2t-d. Just solve for h and that's your answer.
Hopefully this helps!
Answer: they need to cover 0.25 miles.
Step-by-step explanation:
Let x represent the total distance that they have to cover to get to Bernie's house.
Beth and Billy are biking to their friend Bernie's house and after 1 mile, Beth and Billy have traveled 4/5 of the total distance to Bernie's house. This would be expressed as
4.5 × x = 1
4x/5 = 1
Multiplying the left hand side and the right hand side of the equation by 5, it becomes
4x/5 × 5 = 1 × 5
4x = 5
Dividing the left hand side and the right hand side of the equation by 4, it becomes
4x/4 = 5/4
x = 1.25
Therefore, the remaining distance that they need to cover to arrive at Bernie's is
1.25 - 1 = 0.25 miles
Answer:
A and B are correct
Step-by-step explanation:
if x:y is 1:3 then x is 1 and y is 3
1/3 of 3 is 1 so A is correct
3/4(1+3) is 3 so B is correct
But
1/4 × 3 is not 1 so C is not correct
3/4 ×1 is not 3 so D isn't correct
Answer:
A) 4 students
B) 32.5%
C) 19/40
Step-by-step explanation:
Using set notation to solve the problem with universal set n(U) = 40
Let n(A) be the number of students that pass account
n(E) be the number of students that pass economics
n(M) be the number of students that pass mathematics
n(AUEUM)' be number of students that failed in all the 3 subjects.
n(AUEUM) be number of students that pass in all the 3 subjects.
n(U) = n(AUEUM)+ n(AUEUM)'
Find the remaining solution in the attachment
of 54 are the ones which have chocolate , so we need to multiply the fraction by 54
Since 30 pieces of candy have chocolate, then 24 don't have it.
