Answer:
66
Step-by-step explanation:
To find the range, find the difference between the smallest and largest values
The largest value is 193 and the smallest is 127
193 - 127
= 66
4/17 is considered a proper fraction
Answer:
14.83m
Step-by-step explanation:
In an equilateral triangle, of side l and altitude h we have:
h=l/2×sqrt(3).
l=2h/sqrt(3)=2×12.84/1.73=14.83m
57 children tickets were sold on Saturday.
You could set this up as a system of equations.
x + y = 155
6.00x + 9.90y = 1312.20
First step is multiplying the first equation by -6 to use the elimination method.
-6.00x + -6.00y = -930
6.00x + 9.90y = 1312.20
The positive and negative 6x cancel out until you are only left with the y.
Combining them would make your equation...
3.9y = 382.2
Next you would divide by 3.9 on both sides to get the y by itself.
The result of that would be y = 98. Which means 98 adult tickets were sold. Then you would plug y into either of the equations to solve for x.
