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%
Let's call the younger student's age A and the older student's age B. The teacher's age will be T.
B = 2A
T = 5B
T+5 = 5(A+5)
Simplify the last equation.
T+5 = 5A+25
T = 5A+20
Now we have two equations solved for T, so we can set them equal to each other.
5B = 5A + 20
We can plug 2A in for B
5(2A) = 5A + 20
10A = 5A + 20
5A = 20
A = 4
To find T, we plug 4 in for A in T = 5A + 20
T = 5(4) + 20
T = 40

<u>ANSWER: </u>
If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1
<u>SOLUTION:</u>
Given, two points on line l have coordinates (0, A) and (2, −3),
And the slope of the line is A,
We need to find a value.
We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by
Here,in our problem,
now, substitute the values in formula we get
2A = -3 –A
2A+ A = -3
3A = -3
A = -1
Hence, the value of A is -1.
