Show all work.-5X - 16 = 8x - 3​

Mathematics

Harman [31]3 years ago
8 0

Answer:

x = -1

Step-by-step explanation:

-5X - 16 = 8x - 3​

add 5x on both sides

⇒ -5X - 16+5x= 8x -3 + 5x    

⇒ -16 = 13x -3

add 3 on both sides

⇒-16 + 3 = 13x -3 +3

⇒ -13 = 13x

divide both sides by 13

⇒ -13/13 =13x/13

∴ -1 = x

The following graph represents an inequality.
Leni [432]

Answer:

Opt. 1 -3 ≤ x ≤ 3

Step-by-step explanation:

Inequalities are regions, the attached picture shows us a region located between -3 and 3, the dots used are solid, this means that the value '3' is include in the region.

Hence the variable is narrowed to -3 and 3.

Find m\angle Cm∠Cm, angle, C.<br> Round to the nearest degree.<br><br> Help Course Challenge
astra-53 [7]
Hello,

1. Since Angle C has the longest side for this triangle, it will have the largest degree value.

2. Use the Law of Cosines and inverse properties of “theta” to solve for Angle C. (Ensure that the calculator used is in “degree mode”, not “radian mode”.

c^2 = a^2 + b^2 - 2(a)(b)(cos (C))
15^2 = 11^2 + 14^2 - 2(11)(14)(cos(C))
225 - 317 = -2(11)(14)(cos(C))
-92 / -2(11)(14) = cos(C)
cos(C) becomes ->> cos^-1[92 /-2(11)(14)] = 72.62° ->> to the nearest degree is 73°

The answer for angle C, 73°, is logical because the triangle in the picture represents a 60-60-60 triangle, known as an equilateral triangle.

Good luck to you!

100 equals 15 minus x divided by 5
zloy xaker [14]
The answer is -485. 

To find this we first need to get rid of the 5 in the denominator. 

100 = \frac{15 - x}{5}

So we multiply each side by 5. 

 500 = 15 - x

Now we need to get rid of the 15. So we subtract 15 from both sides. 

485 = -x

Then since our x is negative, we need to divide by -1. 

-485 = x
