Answer:
1/4
Step-by-step explanation:
1/6 + 1/12 = 1/4
Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
Answer:
725
Step-by-step explanation:
30 - 1 = 29
29 x (25/1) = 725
7 and 21 can cancel leaving a 3 on the bottom. one m can cancel from the bottom and the top so that leaves you with m^3 n^4/3
The ore the answer is B. Why?
Because (-4m+1) + (7m-9) = 3m - 8
You add -4m and 7m and get 3m and the only answer that has a POSITIVE 3m is B.
Anyways, you still have to check it. 1+(-9) is -8. So A+B = 3m - 8
