Answer
They sold 77 student tickets and 53 adult tickets
Step by step explanation
130x5=650
756-650=106
106/2=53
130-53=77
77=student tickets
53=adult tickets
Only in d. are the number related by multiplication (Multiplied by 3 each time to get the next number in the sequence).
3 x 3 =9
9 x 3 =27
27 x 3 = 81 etc.
Answer:
The value of x is 4 and y is (-9)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To </u><u>Find</u>;</h3>
- Value of x
- Value of y
- By Elimination Method
Now, Name the equation
x + 2y = -14 ...(1)
x – y = 13 ...(2)
Now,
x + 2y = -14
x – y = 13
<u>– + –</u>
3y = -27
y = -9
Now, put the value of y in equation 2
x – y = 13
x – (-9) = 13
x + 9 = 13
x = 4
Thus, The value of x is 4 and y is (-9)
<h3>
<u>For </u><u>Verification</u>;</h3>
x + 2y = -14
4 + 2(-9) = -14
4 – 18 = -14
-14 = -14
x – y = 13
4 – (-9) = 13
4 + 9 = 13
13 = 13
Hence, L.H.S = R.H.S

Answer:
J---
Step-by-step explanation:
If she made 1 Dozen (12) and he kids ate 3, (12-3= 9), she needs to make how many more cupcakes, and since we can use a variable, c + 9 = 24 (Because she promised to bring 24------She would need to make 15 more cupcakes)
Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.
