An infinite number of pairs of whole numbers have a sum of 40.
Answer:
Shirt: $45 , Tie: $12
Step-by-step explanation:
Let s be the price of the shirt
Let t be the price of the tie
Given the information from the question,
s + t = 57 - Equation 1
s - t = 33 - Equation 2
We will use substitution method to find the prices.
We will rearranging equation 1.
s = 57 - t
We will substitute s into equation 2.
57 - t - t = 33
57 - 2t = 33
-2t = 33 - 57
-2t = -24
t = -24 / -2
= 12
We now substitute t into Equation 1.
s + 12 = 57
s = 57 - 12
= 45
From here we know, the shirt costs $45 and the tie costs $12

Answer:
8 full bags, 1 party favor left over
Step-by-step explanation:
Given that there are 73 party favors and each bag can hold 9, using division will give us the number of full bags as well as the number of party favors left over. Since 8 x 9 = 72, there would be 8 full bags. 73 - 72 = 1, so there would be one party favor left over.
Answer:
Step-by-step explanation:
Let's find each person's hourly rate. If Kyla can cut and split a cord of wood in 5.5 hours, Kyla can cut and split of a cord of wood in one hour. Similarly, Ronson can cut and spit of a cord of wood in one hour.
Therefore, working together, they can split of a cord of wood.
Thus, it will take them to cut and split a cord of wood.
