Answer:
Step-by-step explanation:
Original cost = $55
Current price = $40
Decrease in price = 40-55 = -$15
Percentage decrease = [(New price - old price)/ old price] *100
Percentage decrease = (40-55)/55] *100
= -0.272727 *100
= -27.27%
To a whole percentage = 27%
Therefore, the cost of the t-shirt decreased by 27%
Answer:
n + (8 + 6)
Step-by-step explanation:
The other 2 choices contain products
When you are given an equation or an expression and told the values for the variables, you can just substitute them into the equation to solve:
8b^2 - 5m + 12
8(6)^2 - 5(8) + 12
8(36) - 40 + 12
288 - 40 + 12
248 + 12

Answer:
x=-5
Step-by-step explanation:
Set up the rational expression with the same denominator over the entire equation.
2x-2/6=3x+3/6
Since the expression on each side of the equation has the same denominator, the numerators must be equal.
2x−2=3x+3
Move all terms containing x to the left side of the equation.
−x−2=3
Move all terms not containing x to the right side of the equation.
-x=5
Multiply each term in x=−5 by −1
x=−5
3x(sqrt 4x+5)/4x+5
You have to multiply the numerator and denominator by sqrt 4x+5 in order to rationalize
