Subtract the polynomials (7.8x - 3.4y + z) and (-9.2x + 4.8y - 2.1z), then place the answer in the proper location on the grid.
Naya [18.7K]
Subtracting the polynomials will give us:
(7.8x-3.4y+z)-(-9.2x+4.8y-2.1z)
=(7.8x+9.2x)+(-3.4y-4.8y)+(z+2.1z)
=17x-8.2y+3.1z

Answer: 17x-8.2y+3.1z

Angles R and S are supplementary angles. which is the measure of R?
ycow [4]

Answer:

<h2>R = 15°</h2>

Step-by-step explanation:

Since angles R and S are supplementary angles it means that the sum of their angles add up to 180°

To find R we must first find x

To find x , add angles R and S and equate them to 180

That's

R + S = 180

80 - x + 3x - 30 = 180

2x + 50 = 180

2x = 180 - 50

2x = 130

Divide both sides by 2

x = 65°

From the question

R = 80 - x

But x = 65°

Substitute the value of x into the expression

That's

R = 80 - 65

We have the final answer as

<h3>R = 15° </h3>

Hope this helps you
