Question

maths question answer the following​

Answer 1

Answer:

3, 9, 167, 8

Step-by-step explanation:

(f) 5 + x/3 = 2x

5 = 2x - x/3 = (6x-x)/3 = 5x/3

x = 5*3/5 = 3

________________________________

(g) 6x = x + 45

6x - x = 45

5x = 45

x = 45/5 = 9

________________________________

(h) 5 + 3x + x = 221

4x = 221-5 = 216

x = 216/4 = 54

Hence, no. of trees planted by section A = 3x + 5 = 3(54) + 5 = 162+5 = 167

________________________________

(i) Man's age = 4(daughter's age) = 4x

4x+16 = 2(x+16)

4x - 2x = 32 - 16 = 16

2x = 16

x = 8 years
