The answer would be D)12/4 because if 4 quarts=1 gallon then 12/4=3 gallons
So, the slope is 2 for each of the points. Now, you plug it into y=mx+bSo, you get, y=2x+b
To find b, you choose any pair of x and y values.-5=-22+bb=17
Answer:
One forth of 20 is 5, so there are 5 kindergarten and first grade classrooms.
5 x 2 is 10 so there are 10 second and third grade classrooms.
10 + 5 is 15.
20 - 15 is 5.
There are 5 forth and fifth grade classes.
Step-by-step explanation:
Answer:
a = 12
Step-by-step explanation:
∠OPQ is a right angle.
![5^{2} + a^{2} = 13^{2} \\25 + a^{2} = 169\\a^{2} = 144\\a = 12](https://tex.z-dn.net/?f=5%5E%7B2%7D%20%2B%20a%5E%7B2%7D%20%20%3D%2013%5E%7B2%7D%20%5C%5C25%20%2B%20a%5E%7B2%7D%20%20%3D%20169%5C%5Ca%5E%7B2%7D%20%3D%20144%5C%5Ca%20%3D%2012)
The side opposite of the smallest angle is the smallest side, so the side opposite of the largest angle is the largest side. So a would be x,z,y because the last angle would be 98 degrees. Hope this helps!
