Answer:
x=-2
Step-by-step explanation:
-9+1=-8 so 2x squared =-8
x=-2
Answer:
<u>x = 6</u>
Step-by-step explanation:
Taking the sides in proportion :
- EB/DC = AB/AC
- 8/24 = -3 + 2x/27
- 1/3 = -3 + 2x/27
- 3(-3 + 2x) = 27
- -9 + 6x = 27
- 6x = 36
- <u>x = 6</u>
Answer:
177 Students
176 Adults
Step-by-step explanation:
Adult - (A) $5
Student - (S) $3.50
Equation 1: A+S = 353 tickets
Equation 2: 5A + 3.50S = $1500
Sub equation 1 into 2:
5A + 3.50(353 - A) = 1500
Multiply: 5A + 1235.50 -3.50A =1500
Subtract 1235.50 and -3.50A from both sides: 1.50A = 264.50 and then divide:
264.50/1.50 = 176 Adults
Sub into equation 1:
176 +S = 353
Solve: 353 - 176 = 177 Students
Check: 5(176) + 3.50(177) = $1500
1499.5 rounded = 1500 = 1500 ✔
I hope this helped!
