Now lets solve the above two equations together by substitution

Total number of students and teachers who rode to the zoo in buses
Total number of students and teachers who rode to the zoo in vans
8√3 · 9√27
8 · 9 ·√3 · √27
72 · √81
72 · 9

From the info 2 jars with 106 sprinkles each, we know 1 jar would have 53 sprinkles.
1 jar has 53 sprinkles.
6 jars have 318 sprinkles because:

13 jars have 689 sprinkles because:
13 × 53 = 689
Answer:
C. N = 400 / 10
Step-by-step explanation:
Lawn-cutting Bank Account = $325
Amount paid for gas = $75
Total amount earned = Lawn-cutting Bank Account + Amount paid for gas
= $325 + $75
= $400
Amount earned per every lawn he mowed = $10
How Many Lawns Did He mow?
Let N = number of lawns he mowed
N = Total amount earned / Amount earned per every lawn he mowed
N = 400 / 10
N = 40 lawns
Answer: x + y
