For this case we can define the following variable:
x: unknown number
We write the equation that models the problem:
From here, we clear the value of x.
We have then:
Answer:
Completing the sentence we have:
0.04 is 1/10 of 0.40
The answer to 51 is more than a number is -12: is 43.
Pretend the cost of the hotel is called "x" and the amusement park is "y"
make the equations.
450=3x+2y and 700=5x+3y
since you're solving for amusement park, you basically just solve for y
multiply the first equation by 5 and the second equation by 3.
2250=15x+10y and 2100=15x+9y
these are a system of equations so subtract one from the other to cancel the x values away.
150=y so the answer is that a day trip to the amusement park costs $150
Answer:
a
Step-by-step explanation:
y= 1/2 ^(x+4)
