Answer:
(1, -1)
Step-by-step explanation:
we isolate y in the first equation
2x+y=1
-2x. -2x
y=1-2x
and now we fill y into second equation
4x-2(1-2x)=6
4x-2+4x=6
8x-2=6
+2 +2
8x=8
/8 /8
x=1
and now to find y we insert x
2(1)+y=1
2+y=1
-2. -2
y= -1
hopes this helps
Answer:
see below
Step-by-step explanation:
342 m/s * 1.09361329834 yd /m * 1 mile / 1760 yards = .21251 mi/s
1500 mi / hr * 1609.344 meters / mile * 1 km / 1000 m = 2414 km/hr
Find A <span>if B is between A and C.
</span><span>A.B,and C are collinear so A, B and C are line up in a line</span>
AC = AB + BC
AB=5x-19,and BC= 3x+4 given;
So
AC = 5x-19 + 3x+4
Simplify
AC = 8x -15
1cm = 10mm
therefore 40cm = 400mm
Answer:
840
Step-by-step explanation:
8×6×15=720
5×6×4=120
720+120=840
