Challenge The price of Stock A at 9 a. m. Was $14.77. Since then, the price has been increasing at the rate of $0.08 each hour. At noon the price of Stock B was $15.27. It begins to decrease at the rate of
$0.16 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the
same?

10 * 563.67 = 5636.7

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

72 is the answer to this problem

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
