Answer:
Step-by-step explanation:
Given the equation y = 0.18x, to solve for x, we will make the variable x as the subject of the formula from the equation given.
From the equation y = 0.18x
Divide both sides by the coefficient of x i.e 0.18
y/0.18 = 0.18x/0.18
y/0.18 = x
Hence the function of the variable x = y/0.18
b) Given the amount of the bill as y and x is the tip in dollars.
Given y = $4.95, we are to substitute the value of y = $4.95 into the resulting function in (a) to get x as shown;
Since x = y/0.18
x = $4.95/0.18
x = $27.5
<em>Hence the bill is $27.5</em>
4x+3 = 2x + 9
4x-2x=9-3
2x=6
x=6/2
x=3
<span>The next larger thousand is 192,000 .
The next smaller thousand is 191,000 .
191,306 is closer to 191,000 than it is to 192,000 .
So the nearest thousand is 191,000 .
