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.
Yes that’s true. You got that correct everyone listen to them.
Answer:
K = 8.3 repeating or 8 1/3
Step-by-step explanation:
3k - 5 = 20
Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )
3k/3 = k
25/3 = 8.3 repeating or 8 1/3
K = 8 1/3 or 8.3 repeating.
Answer:
27000
Step-by-step explanation:
We want to round 27346 to 2 significant figures.
Now, the number already has 5 significant figures, so to reduce it to 2 sig figures, we will have to reduce the 3 digits from the right to zero so that we can have just 2 significant figures by approximating.
Thus, 3 is less than 5 and so 7 cannot increase. Thus, we will have 27000 as the number when reduced to 2 significant figures.
