Answer:
130
Step-by-step explanation:
The two angles with measurements are vertical angles and vertical angles are equal
12x-2 = 10x+20
Subtract 10x from each side
12x-10x -2 =10x-10x+20
2x-2 = 20
Add 2 to each side
2x-2+2 =20+2
2x= 22
Divide each side by 2
2x/2 =22/2
x =11
We want to find 2x-2
12(11)-2
132-2

Answer:
$153.75
Step-by-step explanation:
$71.75 / 7=$10.25

Answer:
Step-by-step explanation:
You do the following.
Take the price of the most expensive subscription and retract the price of the cheap one.
$50-$40 = $10
Since we know what the price of a text message and the difference in dollars between the two subscriptions, we can calculate how many text messages has to be sent. We just divide the result from before ($10) with the price of a text message ($0.2)
$10/$0.2 = 50
The total number of text messages that needs to be send in order for the price of the subscriptions to be the same, is 50.
Answer:
C
Step-by-step explanation:
You can see from the graph that everytime x goes up by 1, y goes down by 4, so the slope is -4.
The y-intercept is at -1
This means that the equation would be C. y = -4x - 1
