1). Two factors of -48 => x * y = -48
=> the absolute values of the two numbers may be:
48 and 1
24 and 2
16 and 3
12 and 4
6 and 8
2). Have a differencie of 19 = > x - y = 19
That makes that the numbers be + 16 and - 3
Because (+16) * (-3) = - 48
And +16 - (-3) = +16 + 3 = 19.
3) The sum of the factors is +16 + (-3) = 16 - 3 = 13.
So the answer is the option C. 13.
7,14,21,28,35,42,49,56,63,70,77,84,91,98,105,112,119,126
18,36,54,72,90,108,126
So the first person to get both of them is the 126th person
25% = 0.25
40 / 0.25 = 160
40 is 25% of 160.
There are 160 children in the club.
(Bowls, Height) (1, 2) (5,5)
Slope is (5-2)/(5-1) = 3/4 inch
y = (3/4)x + b
(2) = (3/4)(1) + b
(2)-(3/4) = b
B=1.25. Y= 0.75*x + 1.25.
Part B
X is the number of bowls in the stack and Y is the corresponding height of the stack.
