The statement A is true since on forming the quadratic equations formed you will find the cost of a message being 15 cents and that of anytime as 10 cents.
Answer:
WVX = 107
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
V + W = 157
V + 50 =157
Subtract 50 from each side
V + 50 -50 =157-50
V = 107

{x + y = 24
{x = 3y </span>
?=6 so the number would be 6365 but sorry if it's wrong :/
4x + 6 < -6
subtract 6 from each side
4x < -12
divide by 4
x < -3
- 2/5 x-9 < 9/10
multiply each side by 10 to get rid of the fractions
10*(- 2/5 x-9) < 10*9/10
distribute
-4x -90 <9
add 90 to each side
-4x < 99
divide by -4 (which flips the inequality)
x> -99/4
x> -24 3/4
