D.square</span>
Answer:400
Step-by-step explanation:
2x + 3y = 1200
3y = -2x + 1200
y = (-2x/3)x + 1200/3
the slope is -2/3x the y intercept is 40
Answer:
x=-14
Step-by-step explanation:
10
using the second equation you can get s=-2. then plugging that into the first you get
-9(-2)-8 = 18-8 = 10
Answer: $400
Step-by-step explanation:
So first you set it up in a equation. You put the amount she put in the bank over x (the x represents her full salary) which equals the percent she already spent over her full salary. That would be 120/x=30/100 you would then cross-multiply to get 12,000 = 30x. you then divide 30 from both sides to get x =400.
