Answer:2x-y-6=0 & 2x-y=6

Step-by-step explanation:

-3y=-6x+18.

-3y+6x=18

-y+2x=6

2x-y=6

2x-1y=6

2x-y=6

2x-y-6=0

Answer:

y=-6+2x

Answer:

3 pi is greater

Step-by-step explanation:

I don't know the exact amount of pi so I can't multiply it, but I do know that it starts with 3.14159 which is greater than 3 (which is what you have to multiply by 3 to get 9) so the amount will be larger than nine.

Answer:

c = 208.8

Step-by-step explanation:

a. [tex]\frac{c}{7.2} =29[/tex]   To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.

b.  [tex]\frac{c}{7.2} =29[/tex]   You need to move the 7.2 to the other side. So, multiply both sides by 7.2, because it's being divided, so multiplying will cancel it out.

c:  [tex]c = 29 * 7.2[/tex]   Then, multiply 7.2 by 29. (The * symbol means multiply)

d.  c. = 208.8   The answer is 208.8, which is rounded to the tenths place.

Hope this helps! I tried to explain it in detail. :)

Answer:

7280000000 or 7.28^9 (in scientific notation)

Step-by-step explanation:

this question is asking you to transfer numbers out of scientific notation and multiply them. 10^6 is 1 followed by 6 zeros (good trick to remember) or 1000000. when you multiply anything by a power of 10 you just add that many zeroes to it or move the decimal point one point to the left for every zero. so in this example it is 5.2 times 1000000 which is 5200000. we do the same for the other one and we get 1400. When we multiply these two values we get 7280000000 or 7.28^9

Answer: C. x= 1 and x= -4

Step-by-step explanation:

10=4x+6

4=4x subtract 6

1=x divide by 4

and

-10=4x+6

-16=4x subtract 6

-4=x divide by 4

Answer:

  J' = (-2, 4)

Step-by-step explanation:

The transformation for 270° counterclockwise rotation about the origin is ...

  (x, y) ⇒ (y, -x)

The point J is (-4, -2), so the point J' is ...

  J' = (-2, -(-4))

  J' = (-2, 4)

Answer: the Y coordinate is 4

[tex](6 - 2) \times 180 = 4 \times 180 = 720 \\ [/tex]

So the sum of the nterior angles of the figure must equal 720° :

[tex](x - 8) + 4x + 2x + 3x + 2x + 2x = 720 \\ [/tex]

[tex]14x - 8 = 720[/tex]

Plus both sides 8

[tex]14x = 728[/tex]

Divided both sides by 14

[tex]x = \frac{728}{14} = 52 \\ [/tex]

So ;

[tex]x = 52[/tex]

And we're done...

Answer:

x = 7

Step-by-step explanation:

7x-1+6x=90

Combine like terms

13x-1 = 90

Add 1 to each side

13x-1+1 = 90+1

13x = 91

Divide by 13

13x/13 =91/13

x = 7

Step-by-step explanation:

Answer:

4.8548×10^2

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of the decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.

Answer:

72/b = h

Step-by-step explanation:

plug in known values

A = 1/2 (bh)

36 = 1/2 (bh)

goal is to isolate the variable h (height)

multiply both sides by 2 to cancel out 1/2

36 × 2 = 1/2 × 2 (bh)

72 = bh

divide both sides by b (base)

72/b = bh ÷ b

72/b = h

i dont see the value for base given so this would be the final answer as far as i know

=======================================================

Explanation:

The angles (2x+24) and x are same side interior angles. Same side interior angles are supplementary when we have parallel lines.

(2x+24) + (x) = 180

2x+24+x = 180

3x+24 = 180

3x = 180-24

3x = 156

x = 156/3

x = 52

Answer

So im not sure but I think that the answer is x=0.08y-0.18

Step-by-step explanation: Solve for x by simplefying both sides of the equation, then isolating the variable.

Answer:

(2x-5)(4x^2+10x+25)

Explanation:

Factoring difference of cubes (a3−b3): (a−b)(a2+ab+b2)

Here, a is 2x because the cube root of 8 is 2 and the cube root of x3 is x, b is 5 because the cube root of 125 is 5.

Plug the numbers in:

(2x−5)((2x)2+2x⋅5+52)

(2x−5)(22x2+10x+25)

(2x−5)(4x2+10x+25)

Answer:

8x^3 can also be written as [tex](2x)^{3}[/tex].

-125 can also be written as [tex]-5^{3}[/tex].

Factoring the polynomial:

[tex](2x)^3+(-5)^3[/tex]

Just took the test edu2020

Congruent triangles are similar triangles.

The statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]

From the complete question (see attachment), we have the following highlights

The angle at point C of both triangles are congruent

i.e. [tex]\mathbf{\angle ACB \cong ECD}[/tex]

This means that the missing statement of the proof is that the angles at C of both triangles are congruent.

Hence, the statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]
