Step-by-step explanation:
1 min = 60 sec
Boxes both can fold per min = 30 + 20 = 50
No of boxes to fold = 200
Time taken in sec = 200 ÷ 50 = 4 min = 60 x 4 = 240 sec
To find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-
x + 19 = 13
x = ?
13 - 19 = x
<span>13 - 19 = -6</span>
x = - 6
CHECK OUR WORK:-
x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!
So, x = -6
