The division property of equality was used between steps 4 and 5.

D is the answer.

Do you see why?

Step 4 shows -6x = 57.

To reach step 5, Paula used the division property of equality dividing both sides of the equation by -6.

The answer is D. Step 4 and 5 because that is the division property of equality of this problem. Divide -6 to both sides to get x by itself.

The measure of the supplement of an angle is 60° less than four times the measure of the complement of the angle. Find the measu

LenaWriter [7]

Answer:

140° and 50°

Step-by-step explanation:

The supplement of the angle (180 - x)

The complement of the angle = (90 - x)

(180 -x) = 4(90-x) - 60

180 - x = 360 -4x - 60

180 -x = 300 - 4x

180 - x + 4x = 300

180 + 3x = 300

3x = 120

x = 40

The supplement (180 - x) = 180 - 40 = 140°

The complement (90 - x) = 90 - 40 = 50°

Let u = <-9, 4>, v = <8, -5>. Find u - v. <br> URGENT

Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$
