Answer:

x = 1 and y = 1

Step-by-step explanation:

This is a system of equations. To solve it, you need to get one of your variables by itself first. (that means getting the x, or y by itself, just like how you solve equations when you only need to solve for one variable). I decided to solve the first equation, which is -x - 2y = -3 I'll solve it for the x, since there is no number being multiplied to it.

The time it takes me to wash the dishes is uniformly distributed between 5 minutes and 12 minutes. What is the probability that

GalinKa [24]

Answer:

0.2857

Step-by-step explanation:

We define the time it takes to do these dishes to be uniformly distributed between the time 5 minutes and 12 minutes.

a = 5 minutes

b = 12 minutes

Probability of tonight's dish washing being between 6 and 8 minutes

P(6<X<8)

= 8-6/b-a

= 2/12-5

= 2/7

= 0.2857

The probability it will be better 6 and 8 minutes is therefore 0.2857

Part A :

Amiraneli [1.4K]

Answer:

v > -25/p

r = -5 +7/3w

Step-by-step explanation:

-vp + 40 < 65

Subtract 40 from each side

-vp + 40 -40< 65-40

-vp < 25

Divide by -p. Remember to flip the inequality

-vp/-p > 25/-p

v > -25/p

7w - 3r =15

Subtract 7w from each side

7w -7w- 3r =15-7w

-3r = 15-7w

Divide by -3

-3r/-3 (15-7w)/-3

r = -5 +7/3w
