Answer:
x = 37 y = 12
Step-by-step explanation:
Let x be one number
Let y = other number
x+y = 49
x-y = 25
Add the equations together
x+y = 49
x-y = 25
---------------
2x = 74
Divide by 2
2x/2 = 74/2
x =37
x+y = 49
37+y = 49
Subtract 37 from each side
37+y-37 = 49-37
y = 12
Answer:
5: given y=2x-2 new y=2x+2
6: given y=-1/4x+4 new y=-1/4x+7
Step-by-step explanation:
In order to draw x ≤ -10 on a number line, first draw a closed dot at -10. This is because we have a ≤ and not a <. If we had a <, it would be an open dot.
Next, since we want x to be smaller, draw an arrow pointing towards all numbers that are smaller. This arrow would point to the left.
Answer:
75%
36= 100 16= 50% 8= 25%
Lets make percentage = P
(8x x 3x -x ) = ( P x 3x -x) 5 /1/20
= (8 *3) = P x 3 ) x 5 /1/20
reduce = P x 3 x 8 = 24 x 3 x 5 / 1/20
360/24 = 15 x 1/20
5 x 15 = 75%
