Answer:
252
Step-by-step explanation:
t50 = t1 + (n - 1)(d)
= 7 + (50 - 1) (5)
= 7 + (49)(5)
= 7 + 245
= 252
Answer:
x = 58/3
Step-by-step explanation:
We can use cross products to solve this problem
6 7
---------- = -----------
14 x-3
6 * (x-3) = 7 * 14
Divide each side by 6
6 /6* (x-3) = 7 * 14/6
x-3 = 98/6
Add 3 to each side
x-3+3 = 98/6 +3
x = 98/6 +18/6
x = 116/6
Divide the top and bottom by 2
x =58/3
1.50c + 4.00a = 5,050
c + a = 2,200
-1.50 (c + a = 2,200)
1.50c + 4.00a = 5,050
-1.50c - 1.50a = -3,300
2.5a = 1750
a = 700
c + 700 = 2,200
c = 1500
700 adults and 1500 children attended the fair.
Answer: 3:20

36x-8y^2
36(3)-8(-6)^2
