Answer:
16
Step-by-step explanation:
2 x 8 is just another way of saying what would 8 + 8 be
for example, 5x5 would just 25 but 5+5+5+5+5 would also be 25
Hope this helps, sorry im not a good teacher:)
ivied the total number of tennis balls buy the number of cans to see how many tennis balls are in 1 can
9 divided by 3 = 3
there are 3 tennis balls per can
fraction would be 3/1 ( meaning 3 balls to 1 can)
OK first convert one of the equations into Y=MX+b form
Y-2x = 3
Add 2X
Y = 2x +3
Now substitute this equation in the other one.
So it would be
3X - 2Y = 5
3X-2(2x+3) = 5
Now solve for y
3X - 4X - 6 = 5
-1X - 6 = 5
Add 6
-1X = 11
X = -11
Now substitute this into one of the equations
Y - 2X = 3
Y -2(-11) = 3
Y +22 = 3
y = 3-22
y = -19
Point slope form is y - y1 = m(x-x1)
So,
y - (-1) = 2(x - 1)
y + 1 = 2x -2 or y + 1 = 2(x -1)
Hope this helps :)
