You know that no matter what, you will pay 15 dollars during the month. 
45-15=30, so you have 30 dollars left to spend on talking. Now you divide 30 by 0.05 to find the amount of minutes possible. 30/0.05=600, so you can spend 600 minutes talking.

Referring to the Fig. in Question #42, give the coordinates
iragen [17]

Answer:

  (x, y) = (0, -3)

Step-by-step explanation:

The point Y is on the y-axis. Its x-coordinate will be zero, since it is neither left nor right of the y-axis.

The point Y is 3 units below the x-axis, so its y-coordinate is -3. This is the value you can read on the y-axis next to point Y.

  (x, y) = (0, -3)

_____

  U(-5, 0)

  V(-3, 3)

  W(5, 5)

  X(-4, -5)

  Y(0, -3)

  Z(2, -1)

It is a good idea to learn to read coordinates from a graph. You will be doing it a lot. The x-coordinate is the number of units right of the y-axis. The y-coordinate is the number of units up from the x-axis. Left or down makes the coordinate negative.

The measure of 5 of the interior angles of a hexagon are 110, 120, 90, 140, and 125. what is the measure of the smallest exterio
Romashka-Z-Leto [24]

Answer:

A) 40

Step-by-step explanation:

The sum of the interior angles of a regular polygon is:

(n - 2) \times 180

For a hexagon, we put n=6

(6 - 2) \times 180 = 4 \times 180 = 720

Let x be the 6th interior angle, then

x + 110  + 120 + 90 + 140 + 125 = 720

x + 585 = 720

x = 720 - 585 = 135

The largest interior angle is 140°

Therefore the least exterior angle will be:

180 - 140 = 40

The correct choice is A

Solve 25+10*(12-x)=5*(2x-7)
lions [1.4K]
<span>Simplifying 25 + 10(12 + -1x) = 5(2x + -7)
25 + (12 * 10 + -1x * 10) = 5(2x + -7)
25 + (120 + -10x) = 5(2x + -7)
 
Combine like terms: 25 + 120 = 145 145 + -10x = 5(2x + -7)
 
Reorder the terms:
145 + -10x = 5(-7 + 2x)
145 + -10x = (-7 * 5 + 2x * 5)
145 + -10x = (-35 + 10x)
 Solving 145 + -10x = -35 + 10x
 
Solving for variable 'x'.
 
Move all terms containing x to the left, all other terms to the right.
 
Add '-10x' to each side of the equation.
145 + -10x + -10x = -35 + 10x + -10x
 Combine like terms: -10x + -10x = -20x 145 + -20x = -35 + 10x + -10x
 
Combine like terms: 10x + -10x = 0 145 + -20x = -35 + 0 145 + -20x = -35
 Add '-145' to each side of the equation. 145 + -145 + -20x = -35 + -145

Combine like terms: 145 + -145 = 0 0 + -20x = -35 + -145 -20x = -35 + -145

Combine like terms: -35 + -145 = -180 -20x = -180
  Divide each side by '-20'.
x = 9
 Simplifying x = 9.
