Answer:

The answer is 24in a am very sure

Step-by-step explanation:

Answer 2

Answer: The missing side is 24 inches

Step-by-step explanation:

Since it is a right angle that  means that we can use the Pythagorean Theorem formula to solve for   the B.

The formula says that  a^2 + b^2 = c^2   Since we know  a is 18 and c is 30 we will input the value into the formula to solve for b.

18^2 + b^2 = 30^2

324 + b^2 = 900

-324               -324

  b^2 = 576

  b = [tex]\sqrt{576}[/tex]  

  b  = 24

Ana decides to start a lemonade stand. She goes to the store to buy her supplies, and those cost her $50. The city of Richmond also requires anna to pay a fee of $5 per day to set up lemonade stand at the park. Write the equation for her total cost (c) in terms of (d) days.

Answers

Answer:

[tex]c=5d+50[/tex]

Step-by-step explanation:

Given that:

Supplies of the lemonade bought at price = $50

Money paid per day to setup lemonade stand at the park = $5

To find:

Equation of her total cost.

Solution:

Let the number of days = [tex]d[/tex]

Per day cost of setting up the lemonade stand is given as $5.

If the number of days are [tex]d[/tex], then the cost of [tex]d[/tex] days can be found by multiplying the per day cost with the number of days.

Therefore, the expression for cost for [tex]d[/tex] number of days = [tex]\$5d[/tex]

Total cost for [tex]d[/tex] number of days can be found by adding the cost of supplies and cost for [tex]d[/tex] number of days for setting up the stand:

[tex]c=5d+50[/tex]

The order in which we complete an operation is NOT optional. This is because if we do addition or subtraction first, ( which is usually at the end of PEMDAS ) the answer ( even if it looks right ) will always be wrong. Always remember, if you don't do the regular PEMDAS, it will always be wrong.

Factorise the expression 6x^2-13x+6 and hence solve the equation 6x^2-13x+6=0

Answers

Answer:

Part A

The factored form of the expression, 6·x² - 13·x + 6 is (2·x - 3) × (3·x - 2)

Part B

The solution of the equation 6·x² - 13·x + 6 = 0 are x = 3/2 or x = 2/3

Step-by-step explanation:

Part A

The given expression to factorize is 6·x² - 13·x + 6, which can be written as follows;

6·x² - 13·x + 6 = 6·x² - 4·x - 9·x + 6

The 13·x is split at - 4·x - 9·x

6·x² - 4·x - 9·x + 6

2·x·(3·x -2) - 3·(3·x - 2)

Bringing out the common factor (3·x - 2) gives;

(2·x - 3) × (3·x - 2)

Therefore, the expression 6·x² - 13·x + 6 in factored form is (2·x - 3) × (3·x - 2)

Part B

Solving the equation, 6·x² - 13·x + 6 = 0, therefore gives;

6·x² - 13·x + 6 = (2·x - 3) × (3·x - 2) = 0

Therefore, either (2·x - 3) = 0 and x = 3/2 or (3·x - 2) = 0 and x = 2/3

From which we have 6·x² - 13·x + 6 = 0 when x = 3/2 or 2/3 and x = 3/2 or x = 2/3 are the solution of the equation 6·x² - 13·x + 6 = 0.

What value of x makes the equation below true? -26 = 60 + x

Answers

Answer:

x = -86

Step-by-step explanation:

60+ (-86)= -26

Answer:

x = -86

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

-26 = 60 + x

Step 2: Solve for x

Subtract 60 on both sides:                   -86 = xRewrite:                                                  x = -86

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    -26 = 60 - 86Subtract:                              -26 = -26

Here we see that -26 does indeed equal -26.

∴ x = -86 is the solution to the equation.

Evaluate y = 2x + 1 when x= -1

Answers

y = 2x + 1
y = 2(-1) + 1
y= -2 + 1
y= -1

Answer:

y = -1

Step-by-step explanation:

We Know:

y = 2x + 1, and x= -1.

Substitute:

y = 2(-1) + 1

Multiply:

2 * -1 = -2

y = -2 + 1

Add:

-2 + 1 = -1

So,

y = -1.
