Answer:
x > 3
Step-by-step explanation:
3x-9-5x > -3x - 6
3x-5x+3x > -6+9
x > 3
Answer:
A. 0
B. -66
C. 4
D. 998
E. -12
Step-by-step explanation:
A. By definition, the sum of anything and its additive inverse is zero.
__
B. If you have trouble with sums, your calculator can help.
-22 + (-44) = -22 -44 = -66
__
C. -36/x = -9 can be solved by multiplying by x and dividing by -9:
-36 = -9x
-36/-9 = x = 4
Since the product of the divisor and quotient is the dividend, dividing the dividend by either gives the other. Here, your dividend is -36 and your quotient is -9. To find the divisor, you can divide -36 by -9, as we did.
__
D. The absolute value function changes the sign of negative numbers to positive:
|-998| = 998

E. If you have trouble with sums, your calculator can help.
(−2)−[(−3)−(−7)−(−6)]
= -2 -(-3 +7 +6) = -2 -10 = -12
If 
is the first number in the progression, and 
is the common ratio between consecutive terms, then the first four terms in the progression are
We want to have
In the second equation, we have
and in the first, we have
Substituting this into the second equation, we find
So now we have
Then the four numbers are
11c-4c = 7c
5c+2c= 7c
3c+7c= 10c
11c-4c= 5c+2c =A
