Madison has set up a lemonade stand outside her house and sells small cups and large cups of lemonade. Each small cup holds 12 o
Troyanec [42]

Answer:

12x+22(y+10)=1240, y=x

small cups=30

large cups=40

Step-by-step explanation:

let x be the number of small cups and y the number of large cups.

-Given that 10 more cups than small cups of lemonade were sold:

12x+22(y+10)=1240

#Before the 10 more were sold, the number of x and y sold were equal>

x=y\\\\\therefore 12x+22(x+10)=1240\\\\12x+22x+220=1240\\\\34x=1240-220\\\\34x=1020\\\\x=30

The number of small cups sold was 30

#Since, the number of large cups was 10 more, y=x+10=30+10=40

Evgen [1.6K]

Answer:

-7 < -3 because -7 is located to the left of -3 on a number line.

Step-by-step explanation:

This is because -7 is on the left of the -3. In negatives -3 is greater than -7. If it was positive then 7 would be greater than 3. So the answer is A. -7 < -3 because -7 is located to the left of -3 on a number line
