Mathematics

You are given two equations, solve for one variable in one of the equations. Say you solved for x in the second equation. Then, plug in that value of x in the x of the first equation. Solve this (first) equation for y (as it should become apparent) and you'll get a number value. Plug in this numerical value of y into the y of the second equation. Solve for x in the second equation. And there you have it: (x, y)

liraira [26]

Answer: -5/4


Step-by-step explanation:

Apply the fraction rule: a/-b = -a/b

-5/6/2/3

-----------------------------------------------------------------------------------------------------------------

Divide fractions: a/b/c/d = a x d/ b x c

-5 x 3 / 6 x 2

-----------------------------------------------------------------------------------------------------------------

Multiply the numbers: 6 x 2 = 12

-5 x 3 / 12

-----------------------------------------------------------------------------------------------------------------

Multiply the numbers: 5 x 3 = 15

-15/12

-----------------------------------------------------------------------------------------------------------------

Cancel the common factor.3

-5/4

Bill booked a ride to the airport. If it rains, the traffic will be bad and the probability that he will miss his flight is 0.06
kvasek [131]

Answer:0.614

Step-by-step explanation:

Given

Probability he will miss flight if it rains=0.06

Probability he will miss flight it does not rain=0.01

Given the probability of rain=0.21

Therefore Probability that it will not rain=1-0.21=0.79

Probability that he will miss the flight =0.21\times 0.06+0.79\times 0.01=0.0205

P(actual raining and he missed the flight| he miss the flight)=\frac{0.21\times 0.06}{0.21\times 0.06+0.79\times 0.01}

=\frac{0.0126}{0.0205}=0.614
