Answer:
Step-by-step explanation:
Answer: There are 8 cupcakes is needed to make 100 cupcakes.
Step-by-step explanation:
Since we have given that
Number of cupcakes = 12
Part of sticks of butter is needed to 12 cupcakes is given by
According to question, I can only buy whole sticks of butter.
So, to make 100 cupcakes,
Number of whole sticks of butter is given by
So, number of whole sticks of butter to make 100 cupcakes = 8
Answer:
x + y = 3 (1)
55x + 40y = 135 (2)
Step-by-step explanation:
Since x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,
x + y = 3 (1)
Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).
Since the total distance moved is 135 miles, we have
55x + 40y = 135 (2)
So, the system of linear equations that represent the situation is
x + y = 3 (1)
55x + 40y = 135 (2)
