Answer:
Step-by-step explanation:
Put the term x on one side of the equation.
<h3>-5x+2<12</h3>
<u>Subtract by 2 from both sides.</u>
<u>Solve.</u>
<u />
<u>Subtract the numbers from left to right.</u>
⇒ 12-2=10
⇒ -5x<10
<u>Multiply by -1 from both sides.</u>
⇒ (-5x)(-1)>10(-1)
<u>Solve.</u>
<u>Multiply the numbers from left to right.</u>
-5x*-1=5x
10*-1=-10
→ 5x>-10
<u>Divide by 5 from both sides.</u>
→ 5x/5>-10/5
<u>Solve.</u>
<u>Divide the numbers from left to right.</u>
-10/5=-2
- <u>Therefore, the correct answer is x>-2.</u>
I hope this helps you! Let me know if my answer is wrong or not.
Answer:
Noah's expression is wrong because he used the wrong coefficients for the variables, and he used a subtraction sign instead of an addition sign.
The correct expression is 2m + 10c
Step-by-step explanation:
Noah is incorrect because he used the wrong coefficients for both of the variables in the expression.
Since muffins are $2 each, and m is the number of muffins, the amount of money made from the muffins is 2m, not 10m.
Similarly, since cakes are $10 each, and c is the number of cakes, the amount of money made from the cakes is 10c, not 2c.
Noah is also incorrect because he used a subtraction sign instead of an addition sign. The amounts made from the muffins and cakes have to be added together.
Putting all of this together, the correct expression is 2m + 10c.
