Answer:
18 weeks
Step-by-step explanation:
Let the number of weeks be represented by a variable x;
Beginning balance = 450
Ending balance= 180
Amount spent per week= 15
Amount spent in x weeks = 450-180= $270
Total amount spent in x weeks = 15*x = 15x
Equate the above equations to the corresponding dollar amount;
15x=270
Next, solve for x by dividing both sides by 15
x=270/15
x= 18
Therefore, there are 18 weeks in the semester.
Answer:
2 cups
Step-by-step explanation:
Since 1.2 cups of Strawberries gives you 3 grams of sugar, doubling the amount of strawberries would be too much, 6 grams. But, since the amount needed is 2 grams, that is 2/3 of 1.2 cups of strawberries. 2/3 of 1.2 is 0.8, so add the original amount of srawberries with 2/3 of the 1.2 cups and you get 1.2 cups+ 0.8 cups= 2 cups
Took me about 45 min to get the answer and for me it is.
