Answer:
20
Step-by-step explanation:
Average = sum of numbers divided by number of numbers
sum of p q and r: 40*3=120
sum of a b c and d: 5*4=20
sum of a b c d p q r: 120+20=140
average of a b c d p q r: 140/7, or 20
Answer: 4z + 3
Step-by-step explanation:
Number of books read by Zeke = z
Michelle read twice as many book as Zeke. This will be: = 2 × z = 2z
Tay read 3 more books than Zeke. This will be: = z + 3
The expression that represents the total number of books read over the summer by Zeke, Michelle and Tay would be the addition of the books read by each person. This will be:
= z + 2z + z + 3
= 4z + 3
