16x - 5y = -33 First, you subtract 16x from both sides of the
<u>-16x -16x </u> equation
<u>-5y</u> = <u>-16x -33</u> Next, you divide both sides of the equation by -5 to
-5 -5 make "y =" form
y = 16/5x + 33/5
1 2/5 + 3 1/2
= 7/5 + 7/2
= ((7x2)+(7x5))/(5x2)
=(14+35)/10
=49/10
=4 9/10
I think the answer is 1,600 totals students taking metaphysics
Sometimes it helps to draw it...so u can see
7 7
J_______K_________L
|__________________|
4x - 2
since K is the midpoint, it splits the segment in 2 equal parts
JK + KL = JL
7 + 7 = 4x - 2
14 = 4x - 2
14 + 2 = 4x
16 = 4x
16/4 = x
4 = x <====
KL = 7 <===
JL = 4x - 2....4(4) - 2.....16 - 2 = 14 <==
13 is the answer ...
draw a picrure ?
please give me an example .
