Question

Plz Do any 3 i will be Mark you has brilliant ​

Answer 1

Answer:

Step-by-step explanation:

9 ) x + 11 / 7 = 9

X = 7 * 9 -11

X = 63 - 11

= 52

6) 1/3x - 1/5x = 6

LCM = 15

= 5/15x -3/15x =6

2/15x =6

2x = 90

x= 90/2

= 45

7). Side 1 = 6cm

Side 2 = 2x

Side 3 = x

Perimeter = 18cm

6 + 2x + x = 18 cm

6 +3x = 18 cm

3x = 18 cm - 6 cm

3 x = 12 cm

x= 12/ 3

= 4 cm

Side 2. = 2 x = 8 cm

Side 3. = x =. 4 cm

Side 1. = 6 cm

HOpe It helps
