Since the original cost is 2700, the fraction 1890 is of 2700 is 1890/2700. Since they both have a 0 at the end, we can cross that out to get 189/270. Next, since their digits add up to factors of 3 (1+8+9=18 and 2+7=9), we can factor 3 out to get 63/90. Repeating the process since these are factors of 3 too, we get 21/30. Doing it yet again since 21 and 30 are factors of 3, we get 7/10 as our answer

in order to lose 1 pound a person needs to burn about 3,600 more calories than he or she eats and drinks. A person who weighs 15
sattari [20]
Ok so you know that the person burns 3,600 calories in order to lose a pound. If they burn 240 calories per hour, you would just divide 3,600 by 240 to get 15. Since you asked for minutes just multiply by 60 which is 900.

When you divide both sides of an inequality by a negative number, you need to _____ the inequality symbol.
Ahat [919]

Answer:

The correct option is option;

A. Flip

Step-by-step explanation:

When both sides of an inequality is divided by a negative number, it changes the sign of both numbers while their magnitude remain the same;

Therefore, if the right hand side of the inequality is lesser than the left hand side, when the signs of the left and right hand sides of the inequality changes after a division , by a negative number, we have;

The smaller right hand side of the inequality will then have a lesser negative magnitude than the left hand side of the inequality with a higher negative value and the left hand side (with the higher negative value) becomes lesser than the right and therefore, the symbol (sign) of the inequality is flipped

Therefore, when you divide both sides of an inequality by a negative number, you need to <u>flip</u> the inequality symbol.
