what is 1/5 divided by 3/10

Answers

Answer:

2/3

Step-by-step explanation:

When we divide two fractions, such as 1/5 ÷ 3/10, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

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.

y=-4x+3/5
y=1/4x+5
y=-1/4x-1

Answers

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4 and each adult ticket sells for $8.50. The auditorium can hold at most 79 people. The drama club must make no less than $460 from ticket sales to cover the show's costs. If 53 student tickets were sold, determine the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses. If there are no possible solutions, submit an empty answer.

Answers

Answer:

There is no way.

Step-by-step explanation:

4 x 53 = 212.

460 - 212 = 248.

Step-by-step explanation:

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!

10s - 5 = 20


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

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
