Answer:

No real Solutions

Step-by-step explanation:

Step one: The coefficient on -6x is -6. So b= -6

Step two: Add (b/2)^2 to each side. in our case it is 9

x^2-6x+9= -49

Step three: Factor left side

(x-3)^2 = -49

Step four: take the square root

x-3 = ±√-49

Step five: add 3 to both sides

x = 3 ± √-49

So there is no real solutions

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

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

Answer:

the answer is B

Step-by-step explanation:

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

Look at the multiples of the two numbers and find the lowest one that matches e.g.

7 = 7, 14, 21, 28

4= 4, 8, 12, 16, 20, 24, 28

28 is the LCM of 7 and 4

Answer:

Step-by-step explanation:

one away to find to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number . if the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Answers

Answer:

2/3

Step-by-step explanation:

Chloe = 18inches of red licorice.

Reid = 6inches of red licorice

Total = 18 inches + 6 inches

Chloe and Reid have 24 inches altogether

1 yard = 36 inches

Fraction = 24 inches / 36 inches

= 2/3

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:

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.
