Answer:
8.5cm
Step-by-step explanation:
convert 3.4metres to cm that is by multiplying by 100
3.4×100=340cm
1rep 40
?rep 340
that is 340/40
=8.5cm
2-7x +10 =6
2-7(-2)+10
2-14+10
-16+10
-6

Answer:3y=−2x+12
y=(−2x+12)/3
y=-2x/3+4
m=-2/3
perpendicular -1/m=3/2
y=mx+c
y=3/2x+12
2y=3x+12

Answer:
(x, y) = (12, -12)
Step-by-step explanation:
The two equations can be added to solve for x.
(-5x -5y) +(6x +5y) = (0) +(12)
x = 12 . . . . . . . . simplify
-5(12) -5(y) = 0 . . . substitute into the first equation
12 +y = 0 . . . . . . . divide by -5
y = -12 . . . . . . . . subtract 12
The solution is (x, y) = (12, -12).
