Answer:
93 in.
Step-by-step explanation:
triangle- 6*6 = 36 /2= 18
rectangle- 5*15= 75
18+75=93
Answer: True
If one variable goes down, then the other goes up, and vice versa. Think of it like a see-saw. We'll have x on one side pushing down to make y go up. An example of this would be y = 1/x which graphs out a hyperbola.
Answer:
Step-by-step explanation:
y - 9 = -2(x - 1)
y - 9 = -2x + 2
y = -2x + 11
You do this and then you do that
(74 + 78 + 70 + x) / 4 = 80
Divide each number by 4.
18.5 + 19.5 + 17.5 + x = 80
Add the numbers you know so far.
18.5 + 19.5 + 17.5 = 55.5
You need 24.5.
Now, since we divided all the others by 4, we have to multiply 24.5 by 4 to see what the exam score would be.
24.5 * 4 = 98.
To get an average of 80%, the student would need to get a 98 on their fourth exam.
