M = Monthly Allowance.
N = 5/7 of M (Monthly Allowance)
5/7 of 5/7 of M = 9.60
5/7 * 5/7 * M = 9.60
Rearrange the formula to find M
M = 9.60 / (5/7) / (5/7) = 18.816
<h2>Monthly Allowance = $18.816</h2>
Answer:
He drives at 54 mph. He will get 108 miles if he drives at that rate for 2 hours.
Step-by-step explanation:
9 miles in 1/6 of an hour
9x6=driving speed of 54mph
54x2 is 108 miles

my friend answer this same question the other day
Answer:
y=2^x
Step-by-step explanation:
One way to write a line is y=mx+b, where b is a number, m is the slope of the line, and y and x are variables that you can plug numbers into. We know that we have two points, (0,5) and (10,0). To find the slope of a line, we can use the equation

Plugging this in for our points, we get

as our slope (we get -1/2 by dividing both -5 and 10 by 5 from the previous fraction), making our equation y=(-1/2)x+b. Plugging a point in to find out what b is, we get 0=(-1/2)10+b=-5+b. Adding 5 to both sides to separate the b, we get 5=b, making our equation y=(-1/2)x+5. To find out what x is for (x,2), since the y value comes second, we can plug in 2 into our equation to get 2=(-1/2)x+5. Since we want to solve for x, we have to separate it. Subtracting 5 from both sides, we get -3=(-1/2)x. Since we can multiply -1/2 by its reciprocal (switching the numerator and denominator) to get 1 (and therefore x on the right sides as 1*x=x), we multiply both sides by -2 to get 6=x, making the point (6,2)
