Answer:

No it is D.52

Step-by-step explanation:

The angle has to equal 180 degrees.

180-76=104

52 time 2 equals 104

104=104

Answer:

\boxed {\tt D. \ x=52}

Step-by-step explanation:

The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.

2x+76=180

Solve for x by isolating x on one side of the equation.

76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.

2x+76-76=180-76\\2x=180-76\\2x=104

x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

2x/2=104/2\\x=104/2\\x=52

x is equal to 52 and D is the correct answer.

Solve for a -4+2(3a-5)=(1-1a)
Kobotan [32]
Distribute the two to each of the values in the parentheses.
-4 +6a-10= 1-1a

Then move like terms to the same side to simplify.
6a+1a=1+10+4
7a=15
a=15/7

The planet Venus has a mass of 4.869 ∙ 1024 kilograms. Use scientific notation to express the planet’s mass in milligrams. 1 kil
Ostrovityanka [42]
<span>To do this you need to multiple 1,024 by 1,000,000 to get 1,024,000,000 and then convert it to scientific notation. For that you need to know how many places there are after the first number. In this case it is 9. This will be 1.024 x 10^9. You have to remember that it is to the power of however many numbers are after the first. So even though we show 3 digits after the . we still have to include those in the power.</span>

Write an equation for the line that is parallel to the given line and that passes through the given point.
Rasek [7]
Parallel to y = 3/4x - 9 and passes through (-8, -18)

Identify the slope : our slope is 3/4

Remember that parallel equations have the same slope, so both slopes are 3/4

Now, we have to find the y-intercept. Simply plug everything into the slope intercept form equation.

y = mx + b

(-18) = (3/4)(-8) + b

Simplify.

-18 = -6 + b

Add 6 to both sides.

-18 + 6 = b

Therefore, our y-intercept is -12.

Now plug everything into the slope intercept form.

y = mx + b

y = 3/4x - 12
