Answer:
Step-by-step explanation:
total cost of the meal = $120
tip = 20%
tip amount = ?
total cost of the meal with tip = ?
tip amount = tip% 0f total cost of the meal
=20/100 * $120
=$2400/100
=$24
total cost of the meal with tip = total cost of the meal without tip + tip amount
=$120 + $24
=$144
Answer:
y=
x-4
Step-by-step explanation:
3x-2y=7
-3x -3x
-2y=-3x+7
/-2 /-2
y=
x-
perpendicular lines always have opposite reciprocal slopes
3/2--> -2/3
y=-2/3x+b
-2=-2/3(-3)+b
-2=2+b
-2 -2
b=-4
y=-2/3x-4
Answer:
b. (x+6)(x-6)
Step-by-step explanation:
x^2-36 So to get to this answer you can do two things
1. Guess and check
2. Factor it out (which is what I like to do)
In order to get x^2 you need 2xs that are positive which knocks out c and d
Then to get to -36, you need to multiply a positive 6 and a negative 6
(This was poorly explained but if you need anymore help just lmk)
X=child's ticket price

So adult's ticket price would be:

Angle A and angle B sums up to 180 (interior angles)
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
angle A = 6(18)-35 = 73 degrees
