Student's error is –5 < x.
Solution:
Step 1: Given inequality
31 < –5x + 6
Step 2: Subtract 6 from both sides of the inequality.
31 – 6 < –5x + 6 – 6
25 < –5x
Step 3: Multiply both sides by –1 to reverse the inequality.
25 × (–1) > –5x × (–1)
–25 > 5x
Step 4: Divide by 5 on both sides.
–5 > x
The correct answer is –5 > x.
Student's error is –5 < x.
Answer:
x > -2
Step-by-step explanation:
First, you simplify both sides of the inequality by combining like terms
Then, you add 6x to both sides in order to isolate x (bring all the Xs to one side)
Lastly, you divide by 8 in order to cancel out 8x solve for x. Since 8 is not a negative number, you DO NOT flip the sign.
the question says that the total price equalled of the antiques is 70. It also says that she bought a table, which was 44, and 2 chairs (x). We can form this equation.
44 + 2x = 70. <------the 2x comes from 2 times the cost of one chair (x) and the . 44 comes from the cost of the table. The total is 70 dollars.
2x = 26 <-------solve algebraicelyy(sry about by spelling)
x = 13 <-------this is the cost of only one chair.
Answer: $13
