Which equations does the number 7 make true? Select all that apply. 20/21 × _____ = 3/20 13/28 × _____ = 5/2 11/14 × _____ = 11/2 3/35 × _____ = 3/5 5/7 × _____ = 5

Answers

Answer 1
Answer: 11/4 x 7 = 11/2 ; 3/35 x 7 = 3/5 ; 5/7 x 7 = 5. So, the last three you listed work with 7 in the blank.
Answer 2

The equations that the number 7 makes true will be 11/14 × 7 = 11/2, 3/35 × 7 = 3/5, and 5/7 × 7= 5. Then the correct options are C, D, and E.

What is an equivalent expression?

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equations do the number 7 make true will be given as,

Let's check all the options. Then we have

20/21 × 7 = 3/20

20 / 3 ≠ 3 / 20

13/28 × 7 = 5/2

13 / 4 ≠ 5 / 2

11/14 × 7 = 11/2

11 / 2 = 11 / 2

3/35 × 7 = 3/5

3 / 5 = 3 / 5

5/7 × 7= 5

5 = 5

The equations that the number 7 makes true will be 11/14 × 7 = 11/2, 3/35 × 7 = 3/5, and 5/7 × 7= 5. Then the correct options are C, D, and E.

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?​

Answers

Answer:

The perimeter of the triangle can be expressed as 5x + 18.

Step-by-step explanation:

Perimeter of an object is the sum of the length of its sides.

For the required triangle, we have;

length of the base = x

length of the second side = 3x + 9

length of the third side = x + 9

Perimeter of the triangle = length of the base + length of the second side + length of the third side

                                        = x + (3x + 9) + (x + 9)

                                        = x + 3x + 9 + x + 9

                                        = 5x + 18

The perimeter of the triangle can be expressed as 5x + 18.

Step-by-step explanation:

We can simplify this to ...

  b^2 +3(b -b^2) -2a

  = b^2 +3b -3b^2 -2a

  = -2b^2 +3b -2a . . . . . . . simplified form

This can be made easier for evaluation by factoring out b.

  = (-2b +3)b -2a

Using the given values, this is

  = (-2(4) +3)(4) -2(2)

what solution is -5m=8m-2

Answers

Answer:

m=2/13

Step-by-step explanation:

Given function:

-5m=8m-2

Subtract middle value from both side:

[tex]-5m-8m=8m-2-8m[/tex]

Combine like terms:

[tex]-13m=-2[/tex]

Divide both sides by the same term:

[tex]\frac{-13}{13}=\frac{-2}{-13}[/tex]

Divide the terms:

[tex]=\frac{2}{13}[/tex]

Therefore, m=2/13.

parallelogram has vertices at (4,4), (7,4), (5,2), and (2, 2). The parallelogram is translated 7 units down and reflected across the y-axis. What are the coordinates of the first point of its image (4,4)?​

Answers

Answer:

Step-by-step explanation:

So we move the parallelogram down 7 units and get the coordinates: (-3,4) (0,4) (-2,2) (-5,2)

Then the equation for reflecting across the y-axis is (x,y) ---> (-x,y) Then I think you can solve it from there. Just take the x points and make them the opposite charge.
