Question

No.1 Answer the following questions.
1. Two supplementery angles are (13x+4) and (4x+6). Find the value of x.

2. Subtract (4y-6) from (3y-4).

3. Change the subject of the formula v=u+at to a.

4. The side of a cube is a and volume is V. Write a formula for this.​

Answer 1

1.supplementary angle is the sum of two angle must be 180

(13x+4)+(4x+6)=180

17x+10=180

x=10

2.(4y-6)-(3y-4)=0

y - 6+4=0

y=2
