Answer:
I'm pretty sure its b>2
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
3>−b+5
Step 2: Flip the equation.
−b+5<3
Step 3: Subtract 5 from both sides.
−b+5−5<3−5
−b<−2
Step 4: Divide both sides by -1.
-b/-1 < -2/-1
Answer:
b>2
Answer:
$31.5
Step-by-step explanation:
Answer:
Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns x + y = 21 5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105 5x + 10y = 165 Now we combine (add) the equations, which eliminates x altogether. 5y = 60 ... y = 12 From there, x + 12 = 21 ... x = 21-12 ... x = 9 You should double check. Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.
