Answer:
5
Step-by-step explanation:
the distance is just how far away from each other they are.
so, scince they are both on -3 at x, then the difference in y is the distance
C. 4 because 4 is a perfect square, as well as x^2 and 4x
I hope that helps!
You could do this with two weighings assuming its a two pan balance - (1) place three balls on each side - if they balance out then its the remaining three that has abnormal ball (2) out of that group, place one ball on each side - if balances it out, the abnormal ball is the remaining one.
If the weighing in step (1) does not balance out, grab the group of three balls that is light or heavy and repeat step (2) described above.
Answer:
351 adults and 275 students
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 626 tickets were purchased, then s+a=626.
We also know that 74 fewer student tickets then adult tickets. So s+76=a, the number of student tickets plus 76 will be the number of adult tickets.
We will solve by substituting one equation into the other. We substitute a=76+s into s+a=626. Simplify and isolate the variable a.
s+a=626
s+76+s=626
2s+76=626
2s+76-76=626-76
2s=550
s=275
This means that 275 students attended and 351 adults attended since 275+351=626.
Answer:
x = -9
Step-by-step explanation:
First rearrange the terms.
-6x - 6x +3 = 111
Add like terms
-12x + 3 = 111
Subtract 3 from both sides
-12x = 108
Divide -12 on both sides
x = -9
