2 answers:

7 0

Explained --------A one-variable equation is an equation that has exactly one variable in it. Similarly, a one-variable inequality is an inequality that has exactly one variable in it. Setting up one-variable equations and inequalities is an extremely useful tool in mathematics.

Answer:

The steps to doing this are as follows:

1. Identify the unknown and represent it with a variable.

2. Set up an equation or inequality using that variable.

3. Solve the equation or inequality to find an answer to the problem.

For the new expectation, 3 drivers and 2 vans are needed.

To determine, for the new expectation, how many drivers and vans do you need, the following calculation must be performed:

8500 x 1.5 = 12750
5000 x 3 = 15000

Therefore, for the new expectation, 3 drivers and 2 vans are needed.

What is the length of BC in the right triangle below?

gayaneshka [121]

Hey there! :)

Answer:

C. BC = 39 units.

Step-by-step explanation:

Use the Pythagorean theorem to solve for BC. Let BC = c, AB = a, and AC = b.

c² = a² + b²

c² = 15² + 36²

Square and simplify:

c² = 225 + 1296

c² = 1521

c = √1521

c = 39 units.

Therefore:

BC = 39 units.

Solve by completing the square

Sveta_85 [38]

$\qquad\qquad\huge\underline{{\sf Answer}}☂$

Let's solve ~

$\qquad \sf \dashrightarrow \: {x}^{2} + 8x = 33$

$\qquad \sf \dashrightarrow \: {x}^{2} + 8x +16 = 33 + 16$

$\qquad \sf \dashrightarrow \: (x + 4) {}^{2} = 49$

$\qquad \sf \dashrightarrow \: x + 4 = \sqrt{49}$

$\qquad \sf \dashrightarrow \: x + 4 = \pm7$

Hence, there are two solutions ~

1. when x + 4 = 7

$\qquad \sf \dashrightarrow \: x + 4 = 7$

$\qquad \sf \dashrightarrow \: x = 7 - 4$

$\qquad \sf \dashrightarrow \: x = 3$

2. when x + 4 = -7

$\qquad \sf \dashrightarrow \: x + 4 = - 7$

$\qquad \sf \dashrightarrow \: x = - 7 - 4$

$\qquad \sf \dashrightarrow \: x = - 11$

I hope you understood ~

a national park has two options: a $50 pass for all admissions during the year, or a $4 entrance fee each time you enter. Write

frutty [35]

<span>With the variable "y" being used to represent the total cost of going to the park for a year, the first equation would read "y = 50" since it is a one-time, flat cost. The second equation would be "y = 4x", with "x" being used to represent the number of times the person visited the park during the year multiplied by the $4 cost per visit.</span>

A family buys 3 dinners at $9 each, 2 kids’ meals at $4 each, and 4 desserts at $3 each. After using a $10 off coupon, how much

Tomtit [17]

Hi

3 dinners at $9 each.
9 x 3

2 kids' meals at $4 each
9 x 3 + 4 x 2

4 desserts at $3 each
9 x 3 + 4 x 2 + 4 x 3

$10 dollar off coupon
9 x 3 + 4 x 2 + 4 x 3 - 10

Solve using PEMDAS
9 x 3 + 4 x 2 + 4 x 3 - 10 = ?
27 + 8 + 12 - 10 = ?
35 + 12 - 10 = ?
47 - 10 = ?
37

The answer is 37

Hope this helps! :)
