<span>Doug and Ken are driving at the same rate but they are coming from different places, with different distances. Since Doug takes t minutes and he is traveling 5 miles, his equation will be t=5x with x being the rate. Since Ken takes m minutes and he is traveling 7 miles, his equation will be m=7x with x being the rate. The equation that represents their travel would be 7/m = 5/t = x.</span>
Answer:
the correct answer is A, thats when cos of ttheta is
Probability of heads or tails is .5
so you do (.5)^3 and you get D = 0.125
Answer:
Her son is 10 years old.
Step-by-step explanation:
Let son be x
Ellie is 4x
In 5 years time: Her son = x + 5
Ellie = 4x + 5
Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)
Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15
x = 10
A=20-b (1)
1.5a+1.25b=28 (2)
Sub 1 into 2
1.5(20-b)+1.25b=28
30-1.5b+1.25b=28
-0.25b=28-30
-0.25b=-2
b=-2/-0.25
b=8

a=20-8
a=12
