Answer:
first one it is {all -,7}
3 ( x + 1) = 2 ( x + 11) Use the Distributive Property
3x + 3 = 2x + 22 Subtract 2x from both sides
x + 3 = 22 Subtract 3 from both sides
x = 19
Answer:
i think their were 17 do you have any answer choices
The answer is line X. I figured it out by graphing the four lines myself and when you graph line X, the slope is 3 and the y intercept is 5.
I hope this helps! Sorry it was late.
Answer:
Step-by-step explanation:
students = x
non-students=y
x+y=410
y=410-x
3x+7y=1650
3x+7(410-x)=1650
3x+2870-7x=1650
-4x=-1220 (divide both sides by -4)
x=305 y=410-305=105
Hence, 305 students attended and 105 non-students attended
