Answer:
C. 15 Miles
Step-by-step explanation:
3 multiplied by 5 is 15 :)
5.3K+2-2=18.43-2
5.3K=16.43
5.3K/5.3=16.43/5.3
K=3.1
Answer:
Step-by-step explanation:
Answer:
x=5,y=2,z=-1
Step-by-step explanation:
x+y+z=6 ........1
2x-y+3z=5 ..........2
3x+2z=13 ⇒3x=13+2z ⇒ x=(13-2z)/3
substitute for x in equation 1 and 2
13-2z/3+y+z=6 ⇒13/3 -2z/3+y+z=6 ⇒z/3+y=6-13/3
<h2>z/3+y=5/3 first equation</h2>
2(13-2z)/3-y+3z=5
26/3-4z/3-y+3z=5⇒5z/3-y=5-26/3⇒
<h2>5z/3-y=-11/3 second equation</h2><h2>z/3+y=5/3 first equation</h2><h2>eliminate y </h2>
5z/3-y+z/3+y=-11/3+5/3
6z/3=-6/3
<h2>z=-1</h2><h2>x=(13-2z)/3 ( find x, bu substitute z=-1)</h2>
x=(13+2)/3
<h2>x=15/3 ⇒ x=5</h2><h2>x+y+z=6</h2>
5+y-1=6
y=6+1-5
<h2>y=2</h2><h2 /><h2 /><h2 />
