Answer:
(1,3)
Step-by-step explanation:
y = 2x+1
y = 4x-1
Since both equations are equal to y, we can set them equal to each other
2x+1 = 4x-1
Subtract 2x from each side
2x+1-2x = 4x-2x-1
1 = 2x-1
Add 1 to each side
1+1 = 2x-1+1
2 = 2x
Divide each side by 2
2/2 = 2x/2
1 =x
Now we need to find y
y = 2x+1
y = 2(1)+1
y =3
Answer:
22
Step-by-step explanation:
(a*b)-c
(4 * 6) - 2
24 - 2
22
we are given
The ez pay plan costs $0.15 per minute
so, cost is $0.15 per minutes
we have
x minutes on the ez pay plan
so, time for plan is x minutes
total bill = cost * time for plan
now, we can plug values
we get
total bill = $0.15x..............Answer
You would have to divide $16.76 by 4 to find out how much 1 gallon costs and after that multiply the amount a gallon costs by 7 to get your answer
Answer:
RS = 5
Step-by-step explanation:
Since R is between Q and S , then
QS = QR + RS , that is
6x - 3 = 3x - 2 + 2x + 1
6x - 3 = 5x - 1 ( subtract 5x from both sides )
x - 3 = - 1 ( add 3 to both sides )
x = 2
Then
RS = 2x + 1 = 2(2) + 1 = 4 + 1 = 5
