Ur numbers to the left far left r ur x and the ones to right r ur y
Use distributive property for each side of the equation
1.) 10(x+2)>-2(6-9x)
2. 10x + 20> -12+18x
Then whatever you do to one side of the equation, you do to the other. So we’re trying to get x alone on one side.
Subtract 10x from each side
3.)20> -12 + 8x
Add 12 to each side
4.) 32>8x
Divide each side by 8 to get x alone
5.) 4 > x
Answer:

Step-by-step explanation:

Answer:
1,900
Step-by-step explanation:
Since there are 125 envelopes in each box, multiply the number of boxes by the number of envelopes:
18*125 = 2,250
Since she uses 350 of the envelopes, subtract it from the original number of envelopes:
2,250 - 350 = 1,900
So, Nicole has 1,900 envelopes left :)
