Evaluate the expression xy - 4x when x = 2 and y = 7 . Please help.

Answers

Answer 1
6




xy- 4x.

since we know x= 2 and y= 7, we can substitute the values.

(2)(7) - 4(2)

Multiply 2 and 7

14 - 4(2)

Multiply 4 and 2.

14 - 8

Subtract.

14-8= 6

Step-by-step explanation:

9x3= 27

9x4= 36

9x5 = 45
so you have a lateral surface area of 108
add in the triangle pieces that are 3cm on each side and the triangle rule is 1/2 so it would be 6 on each "wing"
so you would have 27+36+45+12 = 120cm2

Answer: x = 31

Step-by-step explanation:

(5x - 16) + (x + 10) = 180

6x - 6 = 180

6x = 186

x = 31

Answer: 31

Step-by-step explanation:

Here,

(5x-16) and (x+10) angles make up to 180. So,

5x - 16 + x + 10 = 180

6x -6 = 180

6x = 180 + 6

6x = 186

x = 186/6

x = 31

Hence, x = 31

How do i do this?
it's too much:(

Answers

Answer: Shown Below

Step-by-step explanation:

Easy, circle the number, then if it is greater than the variable, draw an arrow from the circle to the left. If it is lesser, draw it to the right. If there is a line under the arrow, the circle has to be filled in, otherwise, leave the circle hollow.

Draw a solid circle if it says >_
or just an outline of a circle if it says >

Draw the solid or outline circle on the number it says.

For instance, in number 1 it says
“7 >_ r”

Draw a solid circle (since its >_) on the number 7.

Then draw an arrow to the left of 7 going all the way to zero because 7 is greater than r and we are graphing r.

What is the perimeter of a right triangle if the hypotenuse is 15 centimeters and one of the legs is 9 centimeters?

Answers

Answer:

The perimeter of a triangle is the sum of the lengths of all its sides. In a right triangle, the length of the hypotenuse is the longest side, and the other two sides are called legs.

Given that the hypotenuse is 15 centimeters and one of the legs is 9 centimeters, we can use the Pythagorean theorem to find the length of the other leg. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Therefore, we can write the equation:

c^2 = a^2 + b^2

where c is the length of the hypotenuse and a and b are the lengths of the legs. Substituting the given values, we get:

15^2 = a^2 + 9^2

225 = a^2 + 81

144 = a^2

a = 12

So, the length of the other leg is 12 centimeters. The perimeter of the triangle is the sum of the lengths of the three sides, which is 15 + 9 + 12 = 36 centimeters.

Answer:

36 cm

Step-by-step explanation:

First, we have to find the length of the other leg using the Pythagorean theorem.

For that, let the length of the missing leg be x.

Let us find it now.

x² + 9² = 15²

x² + 81 = 225

Subtract 81 from both sides.

x² = 225 - 81

x² = 144

x = √144

x = 12 cm

So, the length of the missing side is 12 cm.

Now, let us find the perimeter of the triangle.

For that, you can simply add the lengths of three sides.

P = 15 + 9 + 12  

  = 36 cm

What is the area of the rectangle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

The area of the rectangle is calculated by the formula below:-

Area =  Length x Width

Area =  4⁴/₄ x 7⁵/₆

Area = (18 / 4) x ( 47 / 6 )

Area = 141 / 4

Area  =  35⁵/₂₄ square meters

Therefore, the area of the rectangle will be 35⁵/₂₄ square meters.

Answers

Answer:

The inequality that represents all the possible numbers of roses that the florist can still add to the arrangement is:

r + 17 ≤ 36

This means that the total number of roses, including the 17 that have already been used, must be less than or equal to 36. The variable "r" represents the number of additional roses that the florist can add to the arrangement.

The average high temperature in July in Moscow is 23°C. One day in July 2010,

temperature of 39°C was set. How much higher was the record temperature than the
high temperature four days earlier?

2. What is the answer to the hidden question? Show your work.


3. What is the main question?


4. What is the answer to the main question? Show your work.

Answers

he hidden question is what the temperature was four days prior to the record high temperature of 39°C.

To find the temperature four days earlier, subtract 14.2°C from the record high temperature of 39°C:

39°C - 14.2°C = 24.8°C

The main question is how much higher the record temperature was than the high temperature four days earlier.

To find the answer, subtract the temperature four days earlier (24.8°C) from the record high temperature (39°C):

39°C - 24.8°C = 14.2°C.

So, the record temperature was 14.2°C higher than the high temperature four days earlier.

This problem stuck out as one of the hardest I've ever had.
C=5/9(F-32)

I'm only 14, so this is hard for me.

Answers

Here’s The Answer With Step By Step Explanation!!!
C= 5/9(F - 32)

Distribute the 5/9

C= 5/9F - (5/9)(32)

C = 5/9F - 17.78

That is the final answer for C. To find F, do this:

C = 5/9F - 17.78

Add 17.78 to both sides


C + 17.78 = 5/9F

Multiply both sides by 9/5 to cancel out the fraction on the left side

9/5C + (9/5)(17.78) = F

F= 9/5C + 32

Answers

Answer:

y + 10x - 62 = 0

Step-by-step explanation:

Let the linear relation between the two variables  be given by y=mx + c

Now we put the values to get the constants.

58 = 2m + c

52 = 5m + c

solving we get :

52 - 5m = 58 - 2m

or, -6 = 3m

or, m = -2

Now we put those values in the equations

52 = 5m + c

or, 52 = -10 + c

or, c = 62

The equation relating the sunglasses is y + 10x - 62 = 0 .

The angle ratio will be around 252

Answers

Answer:

Below

⬇️

Step-by-step explanation:

1. The hidden question is "What was the high temperature four days earlier?"

2. To find the high temperature four days earlier, we need to subtract 14.2 from the record high temperature of 39°C:

39 - 14.2 = 24.8°C

3. The main question is "How much higher was the record temperature than the high temperature four days earlier?"

4. To find the difference between the record temperature and the high temperature four days earlier, we need to subtract 24.8 from 39:

39 - 24.8 = 14.2°C

So, the record temperature was 14.2°C higher than the high temperature four days earlier.
