Answer 1

Answer:

My answer to this question would be :

6 = 34 - (12+25) + X

6 = -3 + X

9 = X

The probability would be : 9/34 = 0.26

I am not really sure i will check it later and tell you .

I would be happy if you let me know it was wrong or not , too .

a belt and a wallet cost $42.7 belts and 4 wallets cost $213.If the cost of a belt is $x and the cost of a wallet is $y, form two linear equations in x and y and solve them to find the cost of each item

Answers

hope it helps yah T-T

Let, the cost of a belt = x
cost of a wallet = y

Then, system of equations would be:
x + y = 42
7x + 4y = 213

Multiply 1st equation by 4,
4x + 4y = 168
Substitute it from 2nd equation,
3x = 45
x = 15

Now, substitute it in 1st equation,
15 + y = 42
y = 42 - 15 = 27

In short, Belt costs $15 and wallet costs $27

Solve for x. Round to the nearest tenth.​

The sum of five consecutive multiples of 4 is 20.Find the smallest integer.

Answers

Answer:

The smallest integer is -4.

Step-by-step explanation:

Let the smallest integer be x.

Since the integers are all multiples of 4, they are

=> x, x+4, x+8, x+12 and x+16

=> x + x+4 + x+8 + x+12 + x+16 = 20

=> 5x + 40 = 20

Subtract 40 from both sides of the equation

5x +40 - 40 = 20 - 40

5x = -20

Divide both sides by the coefficient of x(which is 5)

[tex]\frac{5x}{5} = \frac{-20}{5}[/tex]

x = -4

∴ the smallest integer is -4.

find the slope of the line passing through the points (5, 6) and (5,-8)

Answers

Answer:

Undefined

Step-by-step explanation:

Slope is equal to the change in y over the change in x.

m = (y₂ - y₁) / (x₂ - x₁)

Let your points (5, 6) be (x₁, y₁) and (5,-8) be (x₂, y₂). Therefore you have

m = (-8 - 6) / (5 - 5) = -14 / 0

Dividing by zero will lead you to have an undefined slope

Tell whether the triangle with the given side lengths is a right triangle

Answers

Answer:

not a right triangle

Step-by-step explanation:

The Pythagorean Theorem states that If a triangle is a right triangle,

the hypotenuse^2 will equal to shorter^2 + longer^2

hypotenuse = 18, shorter side = 4, longer side = 17

18^2 = 4^2 + 17^2

324 = 16 + 289

324 = 305

That is false, therefore the triangle is not a right triangle

What is the equation of the line that passes through the point (-5,5) and has a
slope of -1?

Answers

Answer:

y = - x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (- 5, 5 ) into the partial equation

5 = 5 + c ⇒ c = 5 - 5 = 0

y = - x ← equation of line

Latoya's Fish tank has 16 L of water in it she plans to add 6 L per minute until tank has at least 46 L what is the possible number of minutes Latoya could add water?

Answers

Answer: The possible number of minutes is 5 minutes.

Step-by-step explanation: First, we should subtract: 46 - 16, since we already have 16 liters and need to get up to 46 liters. 46 - 16 gives us 30. 30 means that it is the liters needed to be filled.

Step-by-step explanation 2: Next, we know that 6 liters is filled every minute. So, basically just do 30 divided by 6, which gives us 5. 5 means the minutes.

Sooo, The possible number of minutes to fill the tank by 6 liters would be 5 minutes
