Between which two consecutive steps did mike make a mistake


(I understand where the mistake is but I don't know how it wants me to answer the question)

Answer:

Step-by-step explanation:

Since this is a test/homework, I'll give you a hint.

A triangle always is 180 degrees. If you add up all the sides, it should be 180.

A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.

Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.

Hope this helps!  

Answer:

Step-by-step explanation:

First expand the expression so you know the coefficients of x and y.

4(2x+y+2y) = 4(2x+3y) = 8x+12y

8x+12y  =  8x+12y

6x+7y  ≠  6x+12y

8x+y+2y  = 8x + 3y ≠  8x+12y

8x+4y+8y = 8x+12y = 8x+12y

The equivalent expression is 8x + 4y + 8y.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

4(2x + y + 2y)

This can be simplified as,

8x + 4y + 8y

Thus,

The equivalent expression is 8x + 4y + 8y.

Answer:

Mayra has 13 nickels

Step-by-step explanation:

Given

Represent dimes with D and nickels with N.

So, from the first statement:

[tex]0.10D + 0.05N = 2.95[/tex]

From the second statement:

[tex]D = 2N - 3[/tex]

Required

Find N

Substitute 2N - 3 for D in [tex]0.10D + 0.05N = 2.95[/tex]

[tex]0.10(2N - 3) + 0.05N = 2.95[/tex]

Open bracket

[tex]0.10*2N - 0.10*3 + 0.05N = 2.95[/tex]

[tex]0.20N - 0.30 + 0.05N = 2.95[/tex]

Collect Like Terms

[tex]0.20N + 0.05N = 2.95+0.30[/tex]

[tex]0.25N = 3.25[/tex]

Make N the subject:

[tex]N = \frac{3.25}{0.25}[/tex]

[tex]N = 13[/tex]

Step-by-step explanation:

Answer:

B and H.

Step-by-step explanation:

By the triangle inequality, any two sides of a triangle must be greater than the remaining side.

Triangle 1)

The side lengths are 9, 40, and 41.

We only need to check the two smaller sides. 9 + 40 = 49 which is indeed greater than 41. Therefore, this is indeed a triangle.

Remember that if:

[tex]c^2=a^2+b^2[/tex]

We have a right triangle.

[tex]c^2>a^2+b^2[/tex]

We have an obtuse triangle.

And if:

[tex]c^2<a^2+b^2[/tex]

We have an acute triangle.

In all of these, c is the longest side.

Therefore, we will substitute 41 for c and 9 and 40 for the others:

[tex]41^2\text{ }?\text{ }40^2+9^2[/tex]

Evaluate:

[tex]1681=1681[/tex]

Since the two values are equivalent, the first triangle is a right triangle.

Triangle 2)

Again, adding up the two smaller sides gives that 8 + 10 = 18.

However, 18 is less than 21, so it does not satisfy the triangle inequality.

Therefore, the given side lengths cannot form a triangle.

32/p=10/440

Step-by-step explanation:

1.  Starting with f(x) = 4x, replace 'f(x)' with y:  y = 4x

2.  Interchange x and y:  x = 4y

3.  Solve for y:  y = x/4

4.  Replace this y with 'f^(-1) = ":    f^(-1) = x/4
