Answer:
x= 57/2 or 28.5
Step-by-step explanation:
2x + 123 = 180
2x = 180 - 123
2x = 57
x = 57/2 (fraction form) or 28.5 (decimal form)
Okay so you are correct with the gradient of the perpendicular line it is -5/2 however the equation is not y= -5/2 -1 because it is a new Line and has a new y-intercept therefore its Y=-5/2 + C but you have corrected that when doing the formula and have got the right answer
Answer:
Inequality Equation
= $9 + 20p ≤ $145
The number of people that can go to the amusement park = 6 people
Step-by-step explanation:
Let the number of people who can go to the amusement park be represented as: p
A group of friends wants to go to the amusement park. They have no more than $145 to spend on parking and admission. Parking is $9, and tickets cost $20 per person, including tax.
The term no more than means equal to or less than
Hence, our inequality Equation =
$9 + $20 × x ≤ $145
$9 + 20p ≤ $145
Solving for p
$9 + 20p =& 145
Subtract $9 from both sides
$9 - $9 + 20p =$ 145 - $9
20p = 136
p = 136/20
p = 6.8 people
Since a person cannot be in decimal form, hence: only 6 people can go to the amusement park
