What is the solution for x in the equation?

sladkih [1.3K]

Answer: 2.5

Step-by-step explanation:

-2x + 14 + 10x = 34

8x + 14 = 34

8x = 34 - 14

8x = 20

x = 20/8

x = 5/2

x = 2.5

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre

NeTakaya

Answer:

She caught 10 rabbits

Step-by-step explanation:

Given

Represent Rabbits with R; Squirrels with S and Deer with D

$S = 3D$

$S = R - 5$

$S + R+ D = 10 +4D$

Required

Determine the value of R

$S + R+ D = 10 +4D$

Solve for R

$R = 10 + 4D - D - S$

$R = 10 + 3D - S$

Recall that $S = 3D$

Substitute 3D for S

$R = 10 + 3D - 3D$

$R = 10$

Hence;

She caught 10 rabbits

Solve the equation 3 - 2x = 9 a) x = 3 b)x = -3 c) x = 6 d) x = -6

Elza [17]

Answer:

Option B is correct ...

 $solution \\ 3 - 2x = 9 \\ or \: - 2x = 9 - 3 \\ or \: - 2x = 6 \\ or \: x = \frac{6}{ - 2} \\ x = - 3$ 

hope this helps..

Good luck on your assignment...

The commuting time for a student to travel from home to a college campus is normally distributed with a mean of 30 minutes and a

Rainbow [258]

Answer:

0.1587

Step-by-step explanation:

Let X be the commuting time for the student. We know that $X\sim N(30, (5)^2)$ . Then, the normal probability density function for the random variable X is given by

$f(x) = \frac{1}{\sqrt{2\pi(5)^{2}}}\exp[-\frac{(x-\mu)^{2}}{2(5)^{2}}]$ . We are seeking the probability P(X>35) because the student leaves home at 8:25 A.M., we want to know the probability that the student will arrive at the college campus later than 9 A.M. and between 8:25 A.M. and 9 A.M. there are 35 minutes of difference. So,

$P(X>35) = \int\limits_{35}^{\infty}f(x)dx$ = 0.1587

To find this probability you can use either a table from a book or a programming language. We have used the R statistical programming language an the instruction pnorm(35, mean = 30, sd = 5, lower.tail = F)
