Answer:
212 children, and 265 adults
Step-by-step explanation:
To find the number of children and adults, we can set up a systems of equations.
x= number of children
y= number of adults
Equation 1: Price
1.50x+2.25y=914.25
Equation 2: Total number of people
x+y=477
Now, let's solve the equation using substitution.
Rearrange the second equation to solve for one variable.
x+y=477
x=477-y
Now plug x equals into the first equation, and solve for y.
1.50x+2.25y=914.25
1.50(477-y)+2.25y=914.25
715.5-1.50y+2.25y=914.25
715.5+0.75y=914.25
0.75y=198.75
y=265
We just solved for the number of adults. Now let's plug y equals into the second equation to find the number of children.
x+y=477
x+265=477
x=212
Answer:
30 degrees
Step-by-step explanation:
triangles have 180 degrees
right triangles have a right angle which is 90 degrees
180-90=90
90-60=30
Answer:
2.4 years
equal height is 72 inches
Step-by-step explanation:
initial height of tree one = 36inches
initial height of tree two = 48inches
36 + 15x = 48 + 10x
15x = 12 + 10x
5x = 12
x = 2.4 years
Answer:
1
Step-by-step explanation:
So a palindrome is a word or number that spells the same thing forwards and backward (e.g. tacocat, racecar, 101, 262) Palindrome years occur every 110 years (except at the end of the millennium, in which it is only 11 years). The last one happened in 2002, so the next one won't occur until 2112. Maybe some of us will live to see it!
