Solve the following equation for X. X=
-2x – 3.2 – 15 = 20

Solve The Following Equation For X. X=-2x 3.2 15 = 20

Answers

Answer 1

Answer:

x = -7

Step-by-step explanation:

-2x - 3x = -5x

so then its -5x - 15

you then add 15 to both sides which gives you -5x = 35

divide -5 from each side to get the answer

-7 = x

Answer 2
x = -7

Step-by-step explanation:

-2x - 3x -15 = 20

-5x = 20 + 15

-5x = 35

x = 35/-5

x = -7

Pipers Pizza shop used 18% more cheese this month than last month, due to having a discount on the extra chesse toppings. If the pizza shop used 150 pounds of cheese last month how much did it use this month

Answers

Answer:

177 pounds

Step-by-step explanation:

Create an equation to represent the system.

Since it's 18% more than what was used last month an equation can be written such as the one below:

(118%)( last month's cheese ) = this month's cheese

Convert the percentages into decimals by moving the decimal place at the end of 118.00 two places to the left

118% = 1.18

( 1.18 )( last month's cheese ) = this month's cheese

Next, plug in the number for last month's cheese

( 1.18 )( 150 pounds) =

177 pounds

If:
BC= 4x + 2,
AB = 8x + 8, and
AC = 22,
Find BC.

Answers

Answer:

BC = 6.8

Step-by-step explanation:

The distance from A to B, then from B to C, is the same distance as from A to C.

Thus,

AB + BC = AC

AB = 8x + 8

BC = 4x + 2

AC = 22

AB + BC = AC

(8x + 8) + (4x + 2) = 22

Expanding the parenthesis:

8x + 8 + 4x + 2 = 22

8x + 4x + 8 + 2 = 22

12x + 12 = 22

Subtracting 12 from both sides:

12x = 10

Dividing both sides by 12:

x = 10/12 = 1.2

x = 1.2

We're looking for BC. As we know,

BC = 4x + 2

Let's now put in x = 1.2 into this equation:

BC = 4x + 2

BC = 4 * 1.2 + 2

Since 4 * 1.2 is 4.8:

BC = 4.8 + 2

BC = 6.8

Answer: BC = 6.8

Step 2: Solve for x

Subtract 10 on both sides:                      -4x ≤ 40Divide -4 on both sides:                          x ≥ -10

Here we see that any value x greater than or equal to -10 would be a solution to the inequality.

What is an expression?

An expression is a combination of some mathematical symbol such as an arithmetic operator and variable that are all constrained and create an equation.

In other meaning, expression is beneficial to determine the end or root value of constraint.

For example 3x +5y

As per the given,

take away 1 = x - 1

Multiply the result by 3 = 3(x - 1)

Answers

Question: A restaurant gets an average of 5.3 complaints per day from its patrons. Use the Poisson distribution formula to find the probability that on a given day the restaurant will receive  exactly 4 complaints

Answer:

[tex]P(X=4) = 0.164125[/tex]

Step-by-step explanation:

Given

[tex]\bar{x} = 5.3[/tex] -- average

Required

Determine the probability of receiving 4 complaints in a day

Since, it follows a poisson distribution, the probability is calculated as:

[tex]P(X=x) = \frac{\bar{x}^x * e^{-\bar{x}}}{x!}[/tex]

In this case:

[tex]x = 4[/tex]

So, we have:

[tex]P(X=4) = \frac{5.3^4 * e^{-5.3}}{4!}[/tex]

[tex]P(X=4) = \frac{789.0481 * 0.004992}{4*3*2*1}[/tex]

[tex]P(X=4) = \frac{3.939}{24}[/tex]

[tex]P(X=4) = 0.164125[/tex]

Hence, the probability of exactly 4 complaints is 0.164125 .
