Distance=rate times time
rate=xmiles per hour
time=y hours

total distance=distance1+distance2
distance1=45mph times 2=90mi
distance2=30mph times 3=90mi
total distance=90mi+90mi=180mi

total is 180mi

What’s the answer PLZ???
ollegr [7]
11. Take the logarithm, base X.
  a² - ab = 10
Since we are given that b = a - 2, we can substitute for b to get
  a² - a(a -2) = 10
  a² - a² + 2a = 10 . . . . . eliminate parentheses
  a = 5 . . . . . . . . . . . . . . simplify, divide by 2


_____
Check: a² = 5² = 25
  ab = 5·3 = 15
  X^25/X^15 = X^10 . . . . . the answer works

DF=78, DE=5x-9, and EF-2x+10, find EF
lbvjy [14]

Answer:

As e is point between df. So we can write df as

df = de + ef

As given df = 78 , de = 5x - 9 , ef = 2x + 10.

So we can write

78 = 5x - 9 + 2x + 10

78 = 7x + 1

On subtracting 1 on booth side

78 - 1 = 7x +1 - 1

77 = 7x

On dividing both side by 7.

11 = x

So x = 11.

So ef = 2x + 10 = 2*11 + 10 = 22 + 10 = 32

A friend of yours claims that he can control the roll of a die, increasing his probability of rolling a six. you decide to put h
lana66690 [7]
Answer: No, I do not believe that there is enough convincing evidence to proof that he can control the dice.

When you roll a die, there is a 1/6 probability that you will roll a 6. If you multiply 50 by (1/6) you would expect your friend to roll at least 8 sixes.

He only rolled 3 more sixes than was expected. I would have him roll 50 more times at least to see how he does.
