I think you’re subtracting 5. So now it’s f^-1(x)= 3x+5/2. Not too sure but hope this may help. So, C.

Use the Pythagorean theorem. We have legs with lengths of 15 and 20 miles, now let's solve for the hypotenuse.

$a=15$
$b=20$
$c=?$

$a^2+b^2=c^2$
$15^2+20^2=c^2$
$c^2=400+225=625$
$c=25$

Your answer is 25 miles. Hope this helps! :)

Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his c

9966 [12]

Answer:

Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

$5n+10(n-8)=235.$

Solve this equation:

$5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.$

Answer:

Step-by-step explanation:

If a boat has the speed = 15 miles per hour

Let the speed of the river = v miles per hour

If the boat is moving down stream, that means boat is traveling with the stream of the river.

So the speed of the boat downstream = (15 + v) miles per hour

Since, speed of the river stream is added with the speed of the boat, it will reach the destination earlier than the expectation.
