(a) how many pupils did mr yok
have? (b) how many candies did
he have?

Good morning,

Step-by-step explanation:

Let x be the number of pupils

and y be the number of candies

→ If he gave 2candies to each of his pupils, he would have 49 candies left

means 2x+49=y

→ If he gave 5 candies to each of his pupils, he would have 28 candies left

means 5x+28=y

then

5x+28=2x+49

⇒ 3x=21

⇒ x=7

therefore y=2x+49=2(7)+49=63.

:)

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
