Answer:

3.6 miles

Step-by-step explanation:

For a trip of x miles, there are x-0.5 miles of it that are "additional", which makes (x-0.5)/0.1 additional tenths.

Then the charges (in dollars) are ...

... 3.50 + 0.30(x -0.5)/0.1

Adding a tip of $2 and requiring the total be less than $15 gives ...

... 3.50 + 0.30(x -0.5) + 2.00 ≤ 15.00

... 5.50 + 3(x - 0.5) ≤ 15.00 . . . . simplify a bit

... 4.00 +3x ≤ 15.00 . . . . . . . . . . simplify more

... 3x ≤ 11.00 . . . . . . subtract 4.00

... x ≤ 3.667 . . . . . . divide by 3

Miles are measured in tenths. We cannot go 3.7 miles on $15, but we can go 3.6 miles.

A(n - 3) +8= bn for n please help me
Papessa [141]

Given equation: A(n - 3) +8= bn.

Solution: On the left side of the equation we have A(n-3).

We don't have any sign in between A and parenthesis (n-3).

So, we need to multiply A and (n-3).

We need to apply distributive property to multiply A and (n-3).

Distributing A over (n-3), we get

A(n-3) = A*n - 3*A = An -3A.

Substituting this value in original equation,

An -3A +8= bn.

We need to solve it for n, so we get n terms on a side.

We have An on left side, we need to get rid n from left side.

Subtracting An from both sides, we get

An -3A +8-An= bn-An.

-3A +8 = bn - An.

We can see n is a common factor on rigth side in bn-an.

Factoring out n on right side from bn-an.

-3A +8 = (b - A)n.

Dividing both sides by (b-A),

\frac{(-3A+8)}{(b-A)} = \frac{(b-A)n}{(b-A)}

On right (b-A) paranthiss cancelled and we get n on right side.

\frac{(-3A+8)}{(b-A)} =n   Final answer.

So, that would be our final answer

n = (-3A+8)/(b-A)

I need help with both questions on the screen. if you can only answer one thats fine too!
meriva

Answer:

11. b = 30

Step-by-step explanation:

a^{2} + b^{2} = c^{2}

Substitute

16^{2} + b^{2}  = 34^{2}

256 + b^2 = 1156

b^2 = 1156-256\\b^2 = 900

b = \sqrt{900}

b = 30

Your welcome and don't forget to say <u>Thanks</u>
