Answer:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
Total for students = 6*y = 6y
Total = $1920
8x + 6y = 1920
Hence system of equations are:
y = x + 40
8x + 6y = 1920
Answer:
201
Step-by-step explanation:
If a number is 5 or over, then you round a number up. However, if it is less than 5, then you keep the same number.
Answer:
minus a negative number meand that u are adding its inverse so the equation would look like 4d+1=13. from there u isolate d
4d+1=13
-1 -1
4d=12
d=3
The area of the pond is πr² since the radius, r, is 15ft. you do π×(15)²
you should get 706.86ft²
Answer:
Arithmetic, common difference is -11
Step-by-step explanation:
19, 8, -3, -14
common difference = d = 8 - 19 = -11
-3 - 8 = -11
-14 - (-3) = -11
Arithmetic, common difference is -11
