-3. Put the two equation equal to each other and solve.
4x+18=2x+12
-2x=-2x
2x+18=12
-18=-18
2x=-6
2x/2=-6/2
x=-3
Answer:

Step-by-step explanation:
Hello!
<h2>Answer: </h2>
The price will be $30.
<h2>Explanation:</h2>
To find the selling price, we must calculate 20% of $25 and add it to the price.
20% = 0.20
25 × 0.20 = 5
Add this number to the price of the item.
25 + 5 = 30
Answer:

Step-by-step explanation:
<u>Given Data:</u>
2.45 , 3.50 , 2.89 , 2.99
<u>Arrange it in ascending order.</u>
2.45 , 2.89 , 2.99 , 3.50
Range = Highest No - Lowest No.
Range = 3.50 - 2.45
Range = 1.05
Answer:
y = -3/2 x +13
Step-by-step explanation:
We want our line to be perpendicular to
y = 2/3 x -1
The slope of this line is 2/3 (since it is written in the form y = mx+b and m is the slope)
Perpendicular lines have negative reciprocal slopes
m = -(3/2)
The slope of our new line is -3/2
We can use point slope form of the equation
y-y1 - m (x-x1)
y - 7 = -3/2 (x-4)
Distribute
y-7 = -3/2x +6
Add 7 to each side
y-7+7 = -3/2 x +6+7
y = -3/2 x +13
