Answer:

x^2 + y = 4
x/2 - y^3 = 1

Step-by-step explanation:

Any equation with a product of variables, or with a variable in an exponent or denominator, is not a linear equation. Here, "product of variables" includes powers and roots—any expression with an exponent other than 1, or a total of exponents other than 1.

Help, 3+7x=12, what is x?

liraira [26]

So just your normal equation.
We need to isolate x alone.
First lets write out our equation
3 +7x = 12

Lets do this step by step.

first subtract 3 from both sides.
3 + 7x = 12
-3 = -3 it cancels out on the left side and we solve on the right side.
*************
7x = 9

second we divide both sides by 7
7x = 9
÷7 = 7 we got the x alone and we just write 9/7 as our answer.

x = 9/7

Or as a decimal.
9/7 could be 1.28571428571429

Either will work.
x = 9/7
or
x = 1.28571428571429

Have a nice day. :)

A group of college students were asked about their TV watching habits. Of those surveyed, 30 students watch The Walking Dead, 24

Usimov [2.4K]

Answer: 44 students

Step-by-step explanation:

Let Walking dead be denoted as W

Let Blacklist be denoted as B

Let Game of thrones be denoted as G

Total number of students that watch W = 30

W&G&B = 7

W&B only = 13-7 = 6

W&G only = 10-7 = 3

To get the number of people that watch W ONLY, we subtract those that watch W&B only (6), W&G only(3) and W&B&G(7) from 30. Hence,

W Only = 30 - 6- 3 - 7= 14 (14 students watch Walking dead only)

Total number of students that watch B =24

B&G&W = 7

B&W only = 13-7 = 6

B&G only = 16 - 7 = 9

Hence, those that watch B only = 24-6-9-7= 2 students.

Total number of students that watch G = 22

G&W&B = 7

G&B only = 9

G&W only = 3

Hence those that watch G only = 22-9-3-7 = 3 students.

Hence number of students that watch at least one show = W only + B only + G only + W&B only + W&G only + B&G only + W&B&G.

= 14+2+3+6+3+9+7 = 44 students.
