AB is not parallel to ED because if it were, it would have little arrows to indicate it. Also the measure of angle A is not 60 degrees it would be 140 degrees since angle B and C are 20.
Part A.
Consider a punch containing L liters.
60% of these that is

is grape juice, and the rest, 0.4 L is lemon-soda.
so, for the variable L, the total amount of punch, the total amount of grape juice is 0.6 L
and the amount of lemon soda in the punch is 0.4L
Part B.
For L=2, we substitute and get:
0.6 L=0.6 * 2 liters = 1.2 liters of grape juice
0.4 L = 0.4 * 2 liters = 0.8 liters of lemon soda.
D = 122 - 72
d = 50
180 - (50 + 72)
= 180 - 122
= 58
e = 180 - (72 + 58)
e = 180 - 130
e = 50
answer
d = 50
e = 50
Answer:
y = 3x+9
Step-by-step explanation:
We can use the slope intercept form
y = mx+b
where m is the slope and b is the y intercept
y = 3x +b
Substitute the point into the equation
6 = 3(-1) +b
6 = -3+b
Add 3 to each side
6+3 = -3+3+b
9 = b
y = 3x+9
Answer: d = √10

points:
(10,3) (7,2)
distance formula:
d = √( ( x2 - x1 )² + ( y2 - y1 )² )
———
d = √( ( 7 - 10 )² + ( 2 - 3 )² )
d = √( ( -3 )² + ( -1 )² )
d = √( 9 + 1 )
d = √10
