Solve the equation below.

3+X= -8

Answers

Answer:

x = -11

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

First, subtract 3 from both sides of the equation:

3 + x = -8

x + 3 (-3) = -8 (-3)

x = -8 - 3

Simplify:

x = -8 - 3

x = -11

x = -11 is your answer.

~

The answer is -11. If you +8 to -8 it would cancel out and since you added +8 to that side you have to add +8 to 3 which would make X -11.

The formula K= C + 273 is used to
convert temperatures from degrees
Celsius to Kelvin. Solve this formula
for C.

Answers

C = K - 273
Subtract 273 from both sides
273 cancels on right side

Answer:

c = k - 273

Step-by-step explanation:

solve for c: k = c + 273

flip the equation: c + 273 = k

add -273 to both sides: c + 273 + -273 = k + -273

answer: c = k - 273

Value of s

Answers

Answer:

2.5

Step-by-step explanation:

10s-5=20

(add 5 to both sides)

10s=25

(divide both sides by 10)

s=2.5

Answer:

s = 2.5

Step-by-step explanation:

you need to figure out what multiplied by 10 will give you 25, because then you have to subtract 5 in the second part of the equation to get 20.

10 multiplied by 2.5 equals 25, so s = 2.5

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)

Answers

Answer:

25811

Step-by-step explanation:

We are given the rule [ f(n) = 3n - 1 ] and n represents the term.

First term:

f(n) = 3n - 1

f(1) = 3(1) - 1

f(1) = 3 - 1

f(-1) = 2

Second term:

f(n) = 3n - 1

f(2) = 3(2) - 1

f(2) = 6 - 1

f(2) = 5

Third term:

f(n) = 3n - 1

f(3) = 3(3) - 1

f(3) = 9 - 1

f(3) = 8

Fourth term:

f(n) = 3n - 1

f(4) = 3(4) - 1

f(4) = 12 - 1

f(4) = 11

As you can see, the common difference is 3.

Best of Luck!

Answer:

2,5,8,11

Step-by-step explanation:

If n=1, 3n-1 =3*1-1 =3-1 =2

If n=2, 3n-1 =3*2-1 =6-1 =5

If n=3, 3n-1 =3*3-1 =9-1 =8

If n=4, 3n-1 =3*4-1 =12-1 =11

i can’t graph it, but this is how you would simplify it:

(subtracting is really adding a negative):
|3x+-6|+3<15

3x+6+3<15

3x+9<15 should be the answer, but if it were to act as a ratio this would be the answer:
