Answer: x > 24
Step-by-step explanation: -12x/-1/2x = 24. 24 is the given when dividing. The sign is flipped after dividing negatives.
Remember
(x^m)(x^n)=x^(m+n)
(x^2y^2-5)^2=
(x^2y^2-5)(x^2y^2-5)=
x^4y^4-5x^2y^2-5x^2y^2+25=
Answer:
A cup of yogurt has 175 calories.
Step-by-step explanation:
We can solve for the amount of calories in one cup of yogurt and in one banana by setting up and solving a system of equations. Given the information in the problem '2 cups of yogurt and 3 bananas is 650 calories' and '4 cups of yogurt and 2 bananas is 900 calories' we can set up two equations:
2y + 3b = 650 and 4y + 2b = 900, where 'y' is the cups of yogurt and 'b' is the number of bananas.
Using elimination, we can multiply the first equation by a factor of '-2' and then add the equations together to solve for the remaining variable:
-2(2y + 3b = 650) = -4y - 6b = -1300
-4y - 6b = -1300
<u>+ 4y + 2b = 900</u>
-4b = -400, or b = 100, so each banana has 100 calories, if each banana has 100 calories: 4y + 2(100) = 900 or 4y = 700 or y = 175. So, each cup of yogurt has 175 calories.
The table would have two sides, x and y. The y would be the pretzels that ms.abby brought in and the x would be every student. With 78 in the y spot if the table, the x spot would say 0. Then with the y spot saying 76 the x spot would say 1. And so on
