Step-by-step explanation: its just adding the two numbers from right to left so +3-8= -5   then -5x+7x=2x then 6x^2+3x^2= 9x^2 so putting them together equals 9x^2+2x-5

DUE IN 5 MINUTES MATH QUESTION ​
kumpel [21]

Answer:

x= -10

Step-by-step explanation:

So because the angle 55 is part of the same line as one of the unknown angles you can do 180-55 to find that first angle at the top, which is 125.

Next add all three angles (125 + x + 35 + x + 40)=180

Combine the x values to get 2x and subtract the three values from 180

Then 2x= -20, x should be equal to -10

You can plug x back into the values and check your work by adding all the values again, making it all equal to 180 degrees again

Solve each equation y-6.72=253
diamong [38]
You just need to have the variable by itself, so move the -6.72 to the other side (that will make it +6.72)
So you should have this equation now: y = 253+6.72
Then just add them and you have this: y = 259.72
And that is your answer!

Hope I helped! <3

Step-by-step explanation:

We need to find the LCM of 12 and 9.

  • 9 = 3*3
  • 12 = 2*2*3

<u>Their LCM is:</u>

  • LCM(12, 9) = 2*2*3*3 = 36

Number of light fixtures and light bulbs is 36.

<u>Number of packages will be:</u>

Two angles are supplementary. The measure of the larger angle is 4 more than 3 times the measure of the smaller angle. Find the
m_a_m_a [10]

Answer:

<u>The smaller angle measures 44° and the larger measures 136°</u>

Step-by-step explanation:

Let'e recall that supplementary angles are two angles whose sum is 180° degrees.

Smaller angle = x

Larger angle = 3x + 4

Therefore, we have:

x + 3x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44 ⇒ 3x + 4 = 136

<u>The smaller angle measures 44° and the larger measures 136°</u>
