Help please ............ solve<br><br>Solve<br><br> <br><br>X-3y=z<br>-x+2y=-3
Alenkasestr [34]
You don't need 3 equations to get a general solution.  To do this use the equations x-3y-z=0 and -x+2y+0z= -3.  Start out by letting z = t.  Then solving those 2 equations simultaneously, your x's cancel out leaving you with -y-z=-3.  But since z=t, then -y=-3+t or y=3-t.  Now sub that in for y in the first equation, along with the fact that z=t to get x-3(3-t)-t = 0 and solve for x. x=9-2t.  So a general solution for this would be (9-2t, 3-t, t)

Y = 0.27x<br> What is the constant of proportionality?
umka21 [38]

Hey!

------------------------------------------------

The constant of proportionality is 0.27!

We could write a word problem for this. Like:

Jared had paid $0.27 for one pencil. How much would it cost to buy 5 pencils?

0.27 x 1 = $0.27

0.27 x 2 = $0.54

0.27 x 3 = $0.81

0.27 x 4 = $1.08

0.27 x 5 = $1.35

We can see that if Jared bought 5 pencils for $1.35. Since the proportionality is 0.27 just multiply how many times you need to.

We could also write this as: \frac{0.27}{1}

------------------------------------------------

Hope This Helped! Good Luck!

Answer:

a = 1 and b = 14 or a = 14 and b = 1

Step-by-step explanation:

This means that ab = 14 and a + b = 15. Simple guess and check reveals (1, 14) or (14, 1).
