Answer:
You can wait at the front of the luchline and survey every tenth student.
Step-by-step explanation:
This way it is equal for everyone.
Step-by-step explanation:
-3x - 7y = -63
-(3x + 7y) = -63
3x + 7y = -63/-1
3x + 7y = 63
Value of x
3x + 7y = 63
3x = 63 - 7y
x = (63 - 7y)/3
Value of y
3x + 7y = 63
7y = 63 - 3x
y = (63 - 3x)/7
Answer:
I am pretty sure the answer is 498.
Step-by-step explanation:
You have to solve the parentheses first. So,
9(7 (14-6) -3 x 2)
63 (8) -6)
63(8)-6
63(8) = 504
504-6 = 498
please let me know f this is correct :)
Answer:
Step-by-step explanation:
3(x-2)= -3
Divide both sides by 3
x-2 = -1
add 2 to both sides
x - 2 +2 = -1 + 2
x = 1
