402.25 * 10 = 4,022.5 Since there are five days and 10 laps per day, just multiply the second number by five 4,022.5 * 5 = 20,112.5 meters

Find the size of the angles marked with a letter

Marina CMI [18]

Alternate interior angles on parallel lines via the parallel postulate gives you the angle supplementary to x = 120°, so x = 60°. alternate interior angles on 70° via the parallel postulate gives you y = 70°

Just multiply 9 to the temperature in Cleveland.

$\sf9\times-2=-18$

So the temperature in International Falls is -18<span>°F.

It's not 18, because 18 is warmer than -2, not colder and the question says that International Falls is 9 times <em>colder </em>than Cleveland.</span>

Vsevolod [243]

Answer:

Each Shirt ≈ $2.49

Each Pair of Slacks ≈ $5.99

Each Sports Coat ≈ $7.99

Step-by-step explanation:

Mike took clothes to the cleaners three times last month.

Let S denotes shirts, P denotes pair of slacks and C denotes sports coat.

First, he brought 4 shirts and 1 pair of slacks and paid $15.95.

Mathematically,

4S + P = 15.95 eq. 1

Then he brought 7 shirts, 4 pairs of slacks, and 1 sports coat and paid $49.38.

Mathematically,

7S + 4P + C = 49.38 eq. 2

Finally, he brought 3 shirts and 1 sports coat and paid $15.46.

Mathematically,

3S + C = 15.46 eq. 3

We are asked to find how much was he was charged for each shirt, each pair of slacks, and each sports coat.

4S + P + 0C = 15.95 eq. 1

7S + 4P + C = 49.38 eq. 2

3S + 0P + C = 15.46 eq. 3

We have 3 equations and 3 unknowns, they can be solved simultaneously using calculator or using online system of equations solver.

Using online system of equations solver yields,

S ≈ $2.49

P ≈ $5.99

C ≈ $7.99

So that means Mike was charge $2.49 for each shirt, $5.99 for each pair of slacks and $7.99 for each sports coat.

Factor -1/2out of -1/2x+6

Volgvan

$-\dfrac{1}{2}x+6=-\dfrac{1}{2}\left(\dfrac{-\frac{1}{2}x}{-\frac{1}{2}}+\dfrac{6}{-\frac{1}{2}}\right)=-\dfrac{1}{2}\left(x-\dfrac{6\cdot2}{1}\right)=\boxed{-\dfrac{1}{2}\left(x-12\right)}$
