S=2d
4s+3d=300000-80000
4s+3d=220000, now using s=2d in this equation you get:
4(2d)+3d=220000
8d+3d=220000
11d=220000
d=20000
So each daughter gets 20000 and each son gets 40000.
Answer: Initial Value: 3 Base: 5/4 Domain: (-infinity, infinity) Range: (0, infinity)
Step-by-step explanation:
Function: y = 3(\frac{5}{4} )^{x}
Answer:
8 weeks
Step-by-step explanation:
Let x represent how many weeks they will be in France.
The tour in Britain can be represented by 2x, since it is twice as long as the one in France.
The tour in Germany can be represented by x - 2, since it is 2 weeks shorter.
Create an equation and solve for x:
(x) + (2x) + (x - 2) = 30
4x - 2 = 30
4x = 32
x = 8
So, they will be in France for 8 weeks
Answer:
I think it is one-step because when solving it all you have to do is multiply -5 by -5 to get the answer. m= -20
