To solve this is you have to find the price per ounce for each item by simply dividing the price by the ounces.
For the oat cereal divide $3.90 by 15
3.90/15
.26 per ounce
For the rice cereal divide $3.30 by 11
3.30/11
.30 per ounce
The oat cereal costs less per ounce since it is only .26 per ounce whereas the rice cereal is .30 per ounce.
Hope this helps!
Answer: 31
Step-by-step explanation:
The two disks that we know Gina has are: 2 and 8.
We want to find tha largest sum that Gina's disks can have:
This means that the other 3 disks must be the largest possible ones.
We know that Monique has the disks 7 and 9.
The already taken values are: 2, 7, 8, and 9.
The largest values remaining are:
10, 6 and 5.
Then the largest sum that Gyna's disks can have is given by the scenario where Gina draws these 3 disks, and the sum will be:
2 + 8 + 10 + 6 + 5 = 31
Answer:
20*s+30*l = 280
4*s=l
Step-by-step explanation:
Let's say that the number of small boxes is s and the number of large boxes is l. Then, 20*s equals the amount of books in small boxes (as there are 20 books per small box), and 30*l for the amount of books in large boxes. Then, we know that 4 times the amount of small boxes, s, equals l, so 4*s=l. Then, as we know that the amount of books that can be held is 280, we can add the amount of books for each type of box, or 20*s+30*l, to get 280. Our equations are as follows:
20*s+30*l = 280
4*s=l
As we can define l in terms of s, making it so that we can limit the top equation to 1 variable, we can use this to determine the number of each type of box

Answer: (4, -3)</h3>
==================================================
Work Shown
We'll be using these vector properties
- Rule 1: (a,b) + (c,d) = (a+c, b+d)
- Rule 2: k*(a,b) = (k*a, k*b)
To get the following
-2u + v = -2*(-1, 5) + (2,7)
-2u + v = (-2*(-1), -2*5) + (2,7) .... apply rule 2
-2u + v = (2, -10) + (2, 7)
-2u + v = (2+2, -10+7) .... use rule 1
-2u + v = (4, -3)
