Mathematics
1 answer:
crimeas [40]3 years ago
8 0

Answer:

Step-by-step explanation:

a). Equation: m∠K + 40° + 60° = 180°

    [Since, these angles are located at a point of a straight line so they are   supplementary angles]

b). m∠K = 180° - 100°

    m∠K = 80°

c). Equation: m∠M + m∠K = 180°

   [Since, ∠M and ∠K are the supplementary angles]

d). m∠M + 80° = 180°

    m∠M = 180 - 80

              = 100°

Solve -7(s+2)-12=37<br> What is s
Shkiper50 [21]

Answer:

<em>s= </em>-5.57 (rounded to the nearest hundredth)

Step-by-step explanation:

1. Multiply s and 2 by 7.

You'll get -7s-14. We'll come back to this later

2. Subtract 12 from 37.

You'll get 25

3. Add 14 to both sides so that you cancel out the -14.

The equation stands as -7s= 39

4. Divide both sides by -7 so that we leave <em>s </em>by itself.

s= -5.57142857

What is the value of 2x3 + x2 – x when x = 3?
Bad White [126]

Answer:

12

Step-by-step explanation:

This is assuming that x2 means x to the power of 2 and that the x on the left is to represent multiplying. First, plug in all of the number to get 2*3+3^2-3.Using PEMDAS, you should solve the exponent to get 9. Then, multiply 2 by 3 to get 6. Add 6 to 9 to get 15. Subtract 2 to 15 to get 12.

TL;DR

2*3+3^2-3

6+9-3

15-3
