Respuesta :
460 < 2x + 10 and 2x + 10 < 660
Solve x in each equation:
Rewrite so X is on the left side:
2x +10 >460
Subtract 10 from each side:
2x > 450
Divide both sides by 2:
x > 450 /2
x > 225
2x +10 <660
Subtract 10 from both sides:
2x < 650
Divide both sides by 2:
x < 650 / 2
x < 325
Combine the answer: 225 < x < 325
This means her carb intake needs to be more than 225 and less than 325 grams.
Answer:
225 < x < 325
It represents the amount of carbs consumed is between 225 grams and 325 grams.
Step-by-step explanation:
Given compound inequality:
460 < 2x + 10 and 2x + 10 < 660
460-10 < 2x and 2x < 660 - 10
450 < 2x and 2x < 650
225 < x and x < 325
⇒ 225 < x < 325
Which is the solution of the given compound inequality .
∵ The inequality represents the level in which the amount of carbs consumed in grams lies,
Hence, 225 < x < 325 will represent the amount of carbs consumed is between 225 grams and 325 grams.
