Solve for y by simplifying both sides of the equation, then isolating the variable.
y = 1 - x/3

Beginning with <span>x=3-3y and solving for y, the first step would be to move the constant 3 to the opposite side of the equation by subtracting it from both sides, which leaves x-3 = -3y.

Now divide both sides by the coefficient of y, which is -3 to get (x-3)/-3 = y

This could be rewritten as -(1/3)*(x-3) = y or -x/3 + 1 = y</span>

He should use the Pythagorean Theorem to find the missing length.

Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.

So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5

Therefore, the radius of circle L is 5 feet.

Brilliant_brown [7]

Answer:

Percent increase = 60%

Percent increase with baggage = 83%

Step-by-step explanation:

Given that:

Old price of the ticket = $210

New price of the ticket = $335

Increase amount =335-210 = $125

Percent increase = $\frac{Inrease\ amount}{Old\ price}*100$

Percent increase = $\frac{125}{210}*100 = 0.595*100$

Percent increase = 59.52% = 60%

Additional charges = $125+$50 = $175

Percent increase = $\frac{175}{210}*100$

Percent increase = 83%

Hence,

Percent increase = 60%

Percent increase with baggage = 83%

vampirchik [111]

Answer:

122 km/h

138 km/h

Step-by-step explanation:

distance = speed * time

One bus travels 16 km/h slower than the other

(s * 2) + (s - 16)2 = 520

2s + 2s - 32 = 520

4s = 552

s = 552/4

s = 138 km/h

s - 16 = 122 km/h

I believe it should be B because it says one more than twice the number so that means addition. Also it says twice the number so that should be 2w.
I’m not 100% sure but it is my best guess
