Chapter 12: Q40. (page 691)

Solve the equation. Check your solution.

10-3x=37

Short Answer

Expert verified

The solution of equation is -9.

Step by step solution

01

Step 1. Given Information.

The given equation is 10-3x=37.

02

Step 2. Calculation.

Solve the given equation by shifting the constant from left hand side to right hand side.

10鈭�3x=37鈭�3x=37鈭�10鈭�3x=27

Divide the equation by -3.

鈭�3x鈭�3=27鈭�3x=鈭�9

Hence, the value of x after solving the equation is -9.

03

Step 3. Check the answer.  

Substitute -9 for xinthe given equation

10鈭�3鈭�9=3710+27=3737=37

Since left side is equal to right side. Therefor the solution of the equation is -9

鈭�4and鈭�5

Let 鈭�1and 鈭�2be complementary angles, and let 鈭�2and 鈭�3be supplementary angles. If m鈭�1=x掳 and m鈭�2=2x掳, find x. Then find m鈭�1, m鈭�2, and m鈭�3.

In the diagram shown, m鈭�1=35掳and m鈭�3=110掳. What is m鈭�5?

  1. Tell how 鈭�1and 鈭�2 arerelated. Then find m鈭�2.
  2. Tell how 鈭�3and 鈭�4 arerelated. Then find m鈭�4.
  3. Use what you know about the sum of the measures of the angles of a triangle to find m鈭�5.

Four exterior angles of a convex pentagon have measures 14掳, 87掳, 56掳, and 30掳. Find the measure of the fifth exterior angle.

Tell whether the angles are complementary, supplementary, or neither.
