Answer:
x = 4
Step-by-step explanation:
4(6x+1) +4 =104
-4 -4
4(6x+1) = 100
distribute
24x + 4 = 100
-4 -4
24x = 96
x = 4
To check your work, substitute the x value into the equation.
4(6(4)+1) +4 =104
4(25) + 4 = 104
104 = 104
It is correct, one solution.
Answer:
Correct option: (A) Someone with dangerous material that pass through security.
Step-by-step explanation:
Before boarding a flight every person has to pass through airport security.
The security checks every person thoroughly before they are confirmed as safe to go.
The security checks every person for some harmful substances like, weapons, chemical,etc.
If a person is caught with any of these objects the security stops them from boarding the plane.
So if a person is flagged as a risk by the airport security, he/she should have been carrying any kind of harmful substances.
Thus, the correct option is (A).
Answer:
21.25 m
Step-by-step explanation:
y = Ax² + Bx + C
Set the origin at the middle of the span so that the point (0, 0) is on the curve
0 = A(0)² + B(0) + C means C = 0
The points (200, 85) and (-200, 85) are on the curve
85 = A(200)² + B(200)
85 = A(-200)² + B(-200)
85 - 40000A - B(200) = 85 - 40000A + B(200)
- B(200) = B(200)
-400B = 0
B = 0
85 = A(200)²
A = 85/40000
y = 85x²/40000
y = 85(100)²/40000 = 21.25 m
To figure out how many of the 70 comments were those about questions for Gwen about camping gear, you need to first find the decimal of 30%, which is 0.3. Then the equation should be:
70 x 0.3
