Answer:

x = 4

Step-by-step explanation:

1. Write the equation

3/4x = 2x - 5

2. Get the variables on the same side

Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!

-1.25x = -5

3. Divide both sides by -1.25

x = 4

Sami was asked to solve the following system of equations using substitution.
y=6x -4
y=2x

Here is the work that sami did:

2x = 6x -4
8x = -4
x = -0.5

And then to find y: y= 2 (-0.5) = -1

so Sami's answer for the point of intersection was (-0.5, -1).

Clearly state Sami's one error and then give the correct ordered pair for where the lines cross.

Answers

Answer:

see explanation

Step-by-step explanation:

Sami's error is in the second line of working

2x = 6x - 4  ← correct substitution ( subtract 6x from both sides, Sami has added 6x )

- 4x = - 4 ← correct second line ( divide both sides by - 4 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into the second equation

y = 2x = 2(1) = 2

solution is (1, 2 )

Zach has an above-ground pool that has a radius of 5.5 feet. He wants to put a new wall liner around his pool and needs to know the circumference of the pool. Find the circumference of the pool to the nearest hundredth.

Answers

Answer: 34.54feet

Step-by-step explanation:

Thw circumference of the pool will be calculated by using the formula:

= 2πr

where

π = 3.14

r = 5.5

Therefore, circumference = 2πr

= 2 × 3.14 × 5.5

= 34.54feet

Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.

find the circumference of each circle. Use 3.14 or 22/7 for pi. round to the nearest tenth of necessary.

Answers

Answer:

180 in^2

Step-by-step explanation:

to find the height you need to look at the triangle and apply pythagorean theorem

5^2=x^2=13^2

25+x^2=169

x^2=144

x=12

now we can find the area of the parallelogram:

b*h=area

15*12=180 in^2

The area of the parallelogram is 180 in^2

Answers

Answer:

1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%

2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different

3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

AB = 10 m

Step-by-step explanation:

Given that <ACB = <ECD, then triangles ABC and EDC are similar.

Let the height of the solar panel (AB) be represented by x. Thus by comparing the triangles, we have;

[tex]\frac{x}{6}[/tex] = [tex]\frac{45}{75}[/tex]

45x = 6 x 75

45x = 450

x = [tex]\frac{450}{45}[/tex]

x = 10

The height of the solar panel is determined to be 10 m.

Thanks for the help It was about this time that the pigs suddenly moved into the farmhouse and took up their residence there. Again the animals seemed to remember that a resolution against this had been passed in the early days, and again Squealer was able to convince them that this was not the case. It was absolutely necessary, he said, that the pigs, who were the brains of the farm, should have a quiet place to work in. It was also more suited to the dignity of the Leader (for of late he had taken to speaking of Napoleon under the title of Leader) to live in a house than in a mere sty. Nevertheless, some of the animals were disturbed when they heard that the pigs not only took their meals in the kitchen and used the drawing-room as a recreation room, but also slept in the beds.
