You could say “you had 18 t-shirts and bought 12 more and now you have a total of 30 t-shirts”
Answer:
x=3.5
Step-by-step explanation:
1. Multiply
18x-12=5x+30
2. Move the x's to one side
12x= 42
3. Isolate the variable by dividing
x=3.5
Answer:

Step-by-step explanation:
The distance between two points on the plane is given by the formula below
Therefore, in our case,
Thus,
Therefore, the answer is sqrt(61)
In general,
Remember that
Therefore,
Answer:
x = - 3 ±
Step-by-step explanation:
Given
4x² + 24x = 4 ( divide through by 4 )
x² + 6x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 1 + 9
(x + 3)² = 10 ( take the square root of both sides )
x + 3 = ± ( subtract 3 from both sides )
x = - 3 ±
