Hey!
The answer would be (4,8)
You separate the inequalities first
-2x + 6>-10
-2x + 6<-2
Then you solve the inequalities
X<8
X>4
Then find the intersection
(4,8)
And there you go! Hope this helps!

Answer:

  see attachments

Step-by-step explanation:

These are "one-step" equations.

To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.

To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).

Here are more details for the problems on the first page.

  • w +8 = -3  ⇒  w = -3 -8 = -11
  • z +(-7) = -20  ⇒  z = -20 +7 = -13
  • 1/5x = 11  ⇒  x = 5·11 = 55
  • 1u = -88  ⇒  u = -88/11 = -8
  • 1/9y = -2  ⇒  y = 9(-2) = -18
  • 12 +n = 7  ⇒  n = 7 -12 = -5
  • q +(-4) = 8  ⇒  q = 8 +4 = 12

_____

The second page is solved the same way. It is shown in the second attachment.

kodGreya [7K]

Answer:

Step-by-step explanation:

Use the Law of Cosines to find the measure of angle A from the lengths of the sides.

A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°

B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°

C = 180 - A - B = 95.3°
