You need to get y alone for both equations. for x-y=7, you subract x from both sides. (giving you -y = 7 - x) then, multiply the whole equation by -1 to make the y positive, which gives you y = x - 7.
here is the system in y intercept form so you can graph it easier:
*y = x - 7
*y = x + 4
The amount that you get from rocking chairs is $100 × r which is $100r
and the amount that you gt from bar stools is $40×b which is $40b
The total amount will be the added amount of 100r + 40 b
so answer is 100r+40b
Answer:
the possiblity would be 60/100 because there only 6 possible numbers on the cube you may be caring on the there so 3 would mostly likely be your 4 try
660 yards total ran times how many feet are in each yard (3) , 660 x 3 = 1980 feet to be exact
Answer:
A = ½ (b 1 +b 2)h
Step-by-step explanation:
4 + 12 = 16
16 * 1/2 = 8
8 * 5 = 40
