Answer:
2 1
8 4
10 5
Step-by-step explanation:
We already know that it takes 8 lemons to make 4 cups of lemonade. So, to get the number of lemons needed to make 1 cup of lemonade, we divide the lemons and cups by 4.
8 divided by 4 = 2 and 4 divided by 4 = 1. Therefore, it takes 2 lemons to make 1 cup of lemonade.
By this logic, to figure how many cups are needed for 10 lemons, and since we know 2 lemons = 1 cup of lemonade, we multiply the lemons and cups by 5. 2 times 5 is 10 (lemons) and 1 times 5 is 5 (cups). Therefore, 10 lemons are needed to make 5 cups of lemonade.
To plot this on the coordinate axes, the first point goes (2,1) second being (8,4) and third point being (10,5).

Step-by-step explanation:
Answer:
cos 225° = 
sin 225° =
tan 225° = 1
Step-by-step explanation:
I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45° (225 - 180 = 45)
cos and sin are negative in the 3rd quadrant and the tan is positive
cos 225° = - cos 45° =
sin 225° = -sin 45° =
tan 225° = tan 45° = 1

Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
