Question

D = h + 11

The variable h represents the number of hours worked, and the variable d represents the
amount of dough prepared. How many hours did Patrick work if he prepared 12 kilogrammes of
dough?

Answer 1

Patrick worked 1 hour to prepare 12 kilogrammes of dough, calculated by substituting 12 for d in the equation d = h + 11 and solving for h.

Step-by-step explanation:

The student asked how many hours Patrick worked if he prepared 12 kilogrammes of dough. The given equation is d = h + 11, with d representing the amount of dough prepared in kilogrammes, and h representing the number of hours worked. To find h, simply substitute d with 12 kilogrammes and solve for h:

• d = h + 11
• 12 = h + 11
• h = 12 - 11
• h = 1

Patrick worked 1 hour to prepare 12 kilogrammes of dough.
