Solution
let p be the perimeter of the triangle then
3p=75-2p   collect the like terms
3p+2p=75
5p=75  divide both side by 5
5p/5=75/5⇒p=15.
therefore the perimeter of triangle is 15 units

Answer:

45

Step-by-step explanation:

1/3 of 90

= 1/3 * 90

= 90/3

= 30

Let the missing number be x.

2/3 of x

= 2/3 * x

= 2x/3

30 = 2x/3

Cross multiply,

2x = 30 * 3

2x = 90

x = 90/2

x = 45

Hence,

the missing number is 45.
