Answer:
The correct option is 2.
Step-by-step explanation:
The given inequalities are
.... (1)
.... (2)
Solve each inequality.
Subtract 10 from each side of inequality (1).
Divide both the sides by 2.
The value of x is more than 20.
Subtract 10 from each side of inequality (2).
Divide both the sides by 2.
The value of x is less than 50.
Since x > 20 and x < 50, therefore Malcolm needs to consume more than 20 grams of carbohydrates, but less than 50 grams of carbohydrates.
Hence the correct option is 2.
Positive numbers are always greater than -15. Therefore, it's a greater than.
-2x = - 15
Dividing both sides by -2, we get
x = 7.5
Negative cancels on both sides, so we get a positive equation.
Positive numbers are always greater than -15. Therefore, it's a greater than.
What is greater than or less than?
- Greater than and less than are the comparison symbols.
- When the number is bigger or smaller than the other, then greater than and less than symbols are used.
- If the number is greater than the other, the greater than (>) symbol is used.
- If the number is lesser than the other, the less than the (<) symbol is used.
