Answer:

  1. v = 8
  2. x = -12

Step-by-step explanation:

1. I like to work with positive numbers, so the first thing I'd do is multiply the equation by -1.

  2v + 7 = 23

  2v = 16 . . . . . subtract 7

  v = 8 . . . . . . . divide by 2

<em>Check</em>

  -2(8) -7 = -23 . . . . true

___

2. (x/4) -5 = -8

  x/4 = -3 . . . . . . . add 5

  x = -12 . . . . . . . . multiply by 4

<em>Check</em>

  (-12/4) -5 = -8 . . . . true

I WILL MARK THE BRAINLIEST! I NEED HELP NOW!Ashton is constructing the bisector of MN¯¯¯¯¯¯¯.What should Ashton do for his first
Anika [276]

Question says that "Ashton is constructing the bisector of MN¯¯¯¯¯¯¯."

Now we need find about what should Ashton do for his first step?.


We know that to bisect any line say MN, we need to draw two arc from each end point M and N. Both arcs will intersect only when the width of the compass is more than half of the length of side MN. so that we we can join both intersection points to draw the perpendicular bisector.

Hence correct matching choice is C.

So the final answer is "C. Place the point of the compass on point M and draw an arc, making sure the width of the compass opening is greater than 12MN."

862.4×0.03? A.25.872 B.258.720 C.2587.200 D.25,872.000

<h2>Greetings!</h2>

Answer:

A) 25.872

Step-by-step explanation:

A tip when multiplying numbers that are decimals, make the numbers whole numbers without decimals:

862.4 * 10 = 8624

0.03 * 100 = 3

8624 * 3 = 25,872

Then divide by the amount you multiplied the numbers by:

25,872 ÷(100 * 10) = 25.872

So your answer is A) 25.872

Does anyone know the missing leg of the length?
n200080 [17]

Answer:

Hello! answer: 16

Step-by-step explanation:

These are a bit different instead your solving for B so you have to work backwords so... 20 × 20 = 400 12 × 12 = 144 400 - 144 = 256 now we just find out what multiplied by itself = 256 16 × 16 = 256 therefore b = 16 Hope that helps!
