Answer:
13 children and 9 adults if the total cost is $152.5
Step-by-step explanation:
Let x children and y adults
x + y = 22 (1)
5.5x + 9y = 125.5 (2)
y = 22 - x
5.5x + 9(22 - x) = 125.5
5.5x + 198 - 9x = 125.5
-3.5x = 125.5 - 198
-3.5x = -72.5
x = 20.7
y = 22 - x = 1.3
Which is not possible
If the total cost is $152.5
x + y = 22 (1)
5.5x + 9y = 152.5 (2)
y = 22 - x
5.5x + 9(22 - x) = 152.5
5.5x + 198 - 9x = 152.5
-3.5x = 152.5 - 198
-3.5x = -45.5
x = 13
y = 22 - 13 = 9
Answer:
68.68
Step-by-step explanation:
for an approximate result, multiply the volume value by 1.057
Step-by-step explanation:
OI= 3.2 cm (same as OH)
To find GI, use Pythagoras Theorem (a²+b²= c²)
6.8²+3.2²= 56.48
√56.48= 7.5 cm
hope it helps! please mark me brainliest
thank you! have a good day ahead
if u follow me, i will follow u back
-1 would be your answer. f(0) = -4. f(1) = f(0)+3 so f(1) = -1
