Question

maths plz answer guys​

Answer 1

Step-by-step explanation:

activity 1:x-4=6. x=6+4,x=10

2. 3x=21. x=21/3. x=7

3. 1/4*x=5. x=1/4*5=20

4. 2x+2=10. 2x=10-2. 2x=8. x=4

activity 2:

4x=130-30

4x=

x=/4

x=25

activity 3:perimeter of rectangle=2(l+B)

Lenght +breath =20/2

Lenght +breath=10

let breath be x

Lenght=

x+x+2=10

2x+2 =10

2x=10-2

2x=8

x=8/2

x=4

breath =4 and lenght =2(l+4)

2l+8

2l=-8

l=-8/2

l=-4
