(4x-6)+(8x+18)=180(adjacent angles are supplementary)
4x-6+8x+18=180
4x+8x-6+18=180
12x+12=180
12x=180-12
12x=168
x168/12
x=14
8x+18=y+3 (corresponding angles are equal)
8×14+18=y+3
130=y+3
-y=3-130
-y=-127
y=127
x=14, y=127
Answer:
Speed of the
Motorboat
(in miles per hour) Height of the Parasail
from the Water Surface (in feet)
12.5 5
14.5 10
16.5 15
18.5 20
20.5 25
22.5 30
Step-by-step explanation:
X^2+3x=24, halve the linear coefficient, square it, and add it to both sides
In this case (3/2)^2=2.25
x^2+3x+2.25=26.25 now the left side is a perfect square...
(x+1.5)^2=26.25 take the square root of both sides
x+1.5=±√26.25 subtract 1.5 from both sides
x=-1.5±√26.25
x=-1.5-√26.25 and -1.5+√26.25
x≈ -6.62 and 3.62
Answer: 25
Step-by-step explanation:
21 + 18 +16 + X = 20×4
55 + X = 80
X = 80- 55
Answer:1/24
Step-by-step explanation:
You will do 3/8-1/3 and get 1/24.
