184 adults and 201 children swam that day.
(184 × 2) + (201 × 1.50)
368 + 301.50
669.50
Step-by-step explanation:
1700 + 2029.8x = 9500
2029.8x=9500-1700
x=7800/2029.8
x=3.85
Answer:
A) 8
Step-by-step explanation:
The average of two numbers is 7.
6 and x have an average of 7.
sum of terms / number of terms = average
(6 + x)/2 = 7
6+x = 14
x = 8
The number is 8.
Answer:
-8
Step-by-step explanation:
Evaluate g² - h² when g = -1 and h = 3
g = - 1 ; h =3
g² - h²
(-1)² - 3²
1 - 9
= - 8
