Answer:
y= 3x
Step-by-step explanation:
Answer:
5-(-3y+3z)-3(-5z-y) = 6y+12z+5
Step-by-step explanation:
5−(−3y+3z)−3(−5z−y)
Distribute:
=5+3y+−3z+(−3)(−5z)+(−3)(−y)
=5+3y+−3z+15z+3y
Combine Like Terms:
=5+3y+−3z+15z+3y
=(3y+3y)+(−3z+15z)+(5)
=6y+12z+5
Answer: 1 is correct
2 is correct
3 is correct
4 is correct
5 is correct
6 is correct
7 is correct
8 is wrong it should be because you wouldn't add you would subtract it and the other number is negative so it would be x=-26
9 is correct
10 is correct
13 is correct
14 I think is correct
I think 15 is incorrect because if he says one less than twice the number of last year then I think you first should subtract 1 from 25 and then divide by 2 this would give you 17 packages
and I think 16 is correct too.
Hope this helped
Step-by-step explanation:
I think it would just be (if 7 is x and 14 is y like a table where every 2 are a pair) 2x so the next number in the sequence would be 28
Ralph would need 9 sheets of pink paper if he had 3 sheets of red paper.
The reason of this is because for every 1 piece of red paper there are 3 pieces of pink paper. So if you have 3 pieces of red paper you would do 3x3 which equals 9, and that's your answer.
