Answer:
252 children and 395 adults
Step-by-step explanation:
Make a linear system of equations, where x represents the number of children and y represents the number of adults
x+y=648
1.50x+2.25y=1269
solve using substitution, so y=648-x,
then substitute this into the second equation, so you get 1.50x+2.25(648-x)=1269,
solve for x and you will get x equals the 252
then substitute this into the first equation, so you get 252+y=648
solve and you will get y=395
Answer:
A
[2, -4, -6, -2]
Step-by-step explanation:
The number of glasses is restricted to 44 cups. So the number of iced tea cups and the number of lemonade cups that she can serve is, maximum, 44. Then, if you call x the number of glasses of iced tea and call y the number of glasses of lemonade, you have that the total number of glasses (cups) is x + y. And <span>the equation that represents the number of glasses that she cacn serve is x + y = 44. You can place it in other equivalent ways, for example, solve for y: y = 44 - x. Those two equations are valid answers because they represent the same equation.</span>

Answer:
46872
4687200
46872000
468720000
Step-by-step explanation:
say x is "?"
x ÷ 10000 = 4.6872
multiply 10000 into 4.6872 = 46872
x ÷ 10000 = 468.72
Multiply 10000 into 468.72 = 4687200
For each "0" you would move a decimal to your right when multiplying and move it to your left when dividing
