Answer:
The answer to your question is there were 88 children
Step-by-step explanation:
Data
Total number of people = 188
total cost = $5040
12 more adults than seniors
number of children = ?
adults = a
children = c
Process
1.- Write equations that help to solve this problem
a + c = 188 Equation l
a = c + 12 Equation ll
2.- Solve by substitution. Substitute equation equation ll in equation l
(c + 12) + c = 188
-Solve for c
c + 12 + c = 188
2c + 12 = 188
2c = 188 - 12
2c = 176
c = 176 / 2
c = 88
3.- Conclusion
There were 88 children
Answer:
y=-3x+3
Step-by-step explanation:
Answer:
48/7
Step-by-step explanation:
= 3 <u> </u><u>1</u><u> </u> × 2 <u> </u><u>1</u><u> </u>
5. 7
= <u> </u><u>1</u><u>6</u><u> </u> × <u> </u><u>1</u><u>5</u><u> </u>
5. 7
= <u> </u><u>2</u><u>4</u><u>0</u><u> </u> , if we divide both numbers by 5 we get;
35
= <u> </u><u>4</u><u>8</u><u> </u>

Items bought in total:
4 brothers X two hot dogs and one bag of chips=
4X3=
12.
Hot dogs- x, chips- y.
4y + 8x= $18.20
Chips= $1.25 each so
4($1.25) + 8x= $18.20
5 + 8x= $18.20
8x= $18.20-5
8x= $13.20
x= $13.20/8 [13.20 divided by 8]
x= $1.65
This means that one hot dog= $1.65.
If you’re unsure what to write as the answer I’d suggest that you put all the working out down in your copy/notes.
