Which of the following is NOT a monomial?

(Please don’t just guess, I need this question correct)

A)12xy

B)-8x

C)15

D2x+9

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

Step 2: Divide both sides by 9.

Step 3: Check if solution is correct.

Therefore, y = -2.

Answer:

$8

Step-by-step explanation:

Let x represent the amount of money he has to save each week.

We can use this to set up an equation:

[tex]7x=56[/tex]

Now, we have to "isolate the variable". This means we must have a resulting equation of [tex]x=\text{something}[/tex].

In this case, we can use the Division Property of Equality to divide both sides by 7:

[tex]\frac{7x}{7}=\frac{56}{7}\\x=8[/tex]

Therefore he must say $8 each week for 7 weeks so that he can buy the guitar.

Answer:

Peter.

Step-by-step explanation:

I’m assuming from context (your question was written poorly) you’re asking which student walked farther. This would be Peter. Why? Carol walked only 3/5 miles of the way to school, which would be .6 or .60

Peter walked .65 miles to school which is more than .60

140-50 = 90 90/9 =10

Answer:

30 degrees

Step-by-step explanation:

We know that 2x + 50 and 5x - 80 both add up to 180 degrees because they are co-interior. so, lets simplify it:

2x + 50 + 5x - 80

= 7x - 30

7x - 30 = 180

7x = 210

x = 30 degrees

The equation of second graph is  [tex]d = 2.5 t + 1[/tex]

Step-by-step explanation:

the explicit formula for a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

here a₁ = - 4 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{12}{-4}[/tex] = - 3 , then

[tex]a_{n}[/tex] = - 4 [tex](-3)^{n-1}[/tex]

Answer:

  [tex]\displaystyle \text{series}=\sum_{n=0}^{\infty}{5\cdot(-2)^n}[/tex]

Step-by-step explanation:

The first term is 5 and the common ratio is -2. The general term for n starting at 1 can be written as ...

  an = a1·r^(n-1)

If we start n at 0, then we can eliminate the -1 from the exponent:

The possible range for x, in the terms, of BC is BC < x< 3BC.

In mathematic, there is a rule for triangle side lengths. This rule says that the sum of the lengths of any two sides of a triangle is greater than the length of the one side (third side).  Therefore,

                                           [tex]L1+L2 > L3\; (1)\\ \\ L1+L3 > L2\; (2)\\ \\ L2+L3 > L1\; (3)[/tex]      

The question gives three sides: AB (L1), BC (L2) and x (L3). Also, you know that AB=2 BC.

Applying the equation (1) of rule for triangle side lengths, you have:

L1+L2> L3

AB+BC > x

2BC+BC > x

3BC > x

x< 3BC

Applying the equation (2) of rule for triangle side lengths, you have:

L1+L3 > L2

AB+x >BC

2BC+x > BC

x > -BC

Applying the equation (3) of rule for triangle side lengths, you have:

L2+L3 > L1

BC + x > AB

BC + x > 2BC

x > BC

The intersection of the inequalities results is the solution of this problem.  Then, the possible range for x, in the terms, of BC is BC < x< 3BC. See the attached image.

Answer:

(x, y ) → (x - 4, y - 3 )

Step-by-step explanation:

consider the coordinates of A and A'

A (0, 4 ) , A' (- 4, 1 )

0 to - 4 in the x- direction means subtracting 4

4 to 1 in the y- direction means subtracting 3

then translation rule is

(x, y ) → (x - 4, y - 3 )

Step-by-step explanation:

remember, the sum of all angles in a triangle is always 180°.

and the sum of all angles around one point at one side of a line is also airways 180° (because you can imagine that point to be the center of a circle, and the line would cut that circle in half = 180° for every half).

in the triangle LKM we know 2 angles already :

angle 1 = 44°

angle K = 90° (right angle).

so, angle 2 = 180 - 90 - 44 = 46°

and so, angle 5 = 180 - 46 = 134°.

as the angles around point L on line KL are the angles 2 and 5.

angle 5 = 134°

Using it's concept, it is found that of the students who like the vegetables on their pizza, the percentage that do not like meat is of 76.19%.

[tex]P = \frac{a}{b} \times 100\%[/tex]

In this problem, we have that:

Answer:

See the first 3 problems solved below.

I added the next 3 problems.

Step-by-step explanation:

1.

2x + 4x = 180

6x = 180

x = 30

2x = 2(30) = 60

4x = 4(30) = 120

2.

3x + 6x = 180

9x = 180

x = 20

3x = 3(20) = 60

6x = 6(20) = 120

3.

8x + 10x = 180

18x = 180

x = 10

8x = 8(10) = 80

10x = 10(10) = 100

4.

7x + 8x = 180

15x = 180

x = 12

7x = 7(12) = 84

8x = 8(12) = 96

5.

2x + x = 180

3x = 180

x = 60

2x = 120

6.

2x + 2x = 180

4x = 180

x = 45

2x = 2(45) = 90

The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angles ∠GFH = x and ∠CBD = 2x.

From the figure, the angles ∠GFH and ∠CBD are supplementary angles.

∠GFH + ∠CBD = 180°

x + 2x = 180°

3x = 180°

x = 60°

Then the measure of the angles ∠GFH and ∠CBD will be

∠GFH = 60°

∠CBD = 2 × 60°

∠CBD = 120°

The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.

y-6=x

[tex]\huge\boxed{\sf{x=y-6}}[/tex]

[tex]\mathbb{SOLUTION\;WITH\;STEPS:}[/tex]

Hi! Hope you are having a nice day!

In order to make x the subject, we need to solve for x.

It's easy, right?

We have

y=x+6

Move x to the left. Be sure to use the opposite operation.

y-x=6

Now, move y to the right:

-x=6-y

x=-6+y

or

x=y-6

There's an easier way:

y=x+6

y-6=x

x=y-6 (See? We ended up with the same answer :) )

Hope you could understand everything.
