Answer:
The answer to your question is 14.5 weeks
Step-by-step explanation:
Data
Total cost = C = $87
money earned = m = $6
Number of weeks to have the money = w = ?
Process
1.- Write an equation that represents the situation
Weeks = Total cost / Money earned
w = C/m
2.- Substitute the values
w = 87 / 6
3.- Result
w = 14.5
4.- Conclusion
Niki will last 14.5 weeks to have enough money to buy a dog bed.
For a percentage, the denominator should be 100 so,
7×10/10×10
=70/100=70%
answer=70%

Answer:
If 23-26, that is -3
Well, because 23 can't minus 26, that's why you have to rearrange so that you can find the correct answer by letting -26 + 23.
-4y+5x=8
3y-3x=-3 --> divide by (3) y-x=-1
then multiply by (4) 4y-4x=-4
-4y+5x=8
4y-4x=-4
---------------
x=4
then plug x=4 in
4y-4x=-4
4y-4(4)=-4
4y-16=-4
4y=12
y=3
solution: (4;3)
