Answer:
B.
Step-by-step explanation:
The inequality "B" is correct because when you simplify it, you can see that it holds true:
49 > 29
49 is indeed greater than 29, making this inequality true.
The answer to the first one is y=2 and x=6 and for the second one it is y=2 and x=6
Answer:
2400cm^2
Step-by-step explanation:
50 * 10 = 500
(40 * 30 / 2) * 2 = 1200
30 * 10 = 300
40 * 10 = 400
Now add them all together.
500 + 1200 + 300 + 400 = 2400
Answer:
y=5x+42
subtract 5x from both sides
-5x+y=42
Step-by-step explanation:
subtract 5x from both sides
-5x+y=42
multiply by -1
5x-y=-42
In standard form, Ax+By=C, the variable A cannot be a negative. However, this is not an option so go with c.
