Answer:
m > -5
Step-by-step explanation:
Divide your inequality by the coefficient of m, which is -3. Doing that requires you reverse the comparison symbol:
(-3m)/(-3) > (15)/(-3)
m > -5
_____
The comparison symbol is reversed whenever an inequality is multiplie or divided by a negative number. You might be able to see why when you look at the relation between a couple of integers:
-2 < -1
2 > 1 . . . . . . multiply the above by -1
Multiplying by a negative number effectively reflects the comparison across the center of the number line. As we know from looking in a mirror; reflection reverses left and right, so numbers that were farther to the right (more positive) are now farther to the left (more negative).
1.
s = 2(lw) + 2(lh) + 2(wh)
s = 2(2cmx3cm) + 2(2cmx4cm) + 2(3cmx4cm)
s = (2 x 6cm) + (2 x 8cm) + (2 x 12cm)
s = 12cm + 16cm + 24cm
s = 28cm + 24cm
s = 52cm^2
answer= 3rd option
2.
s = 2(lw) + 2(lh) + 2(wh)
s = 2(1mx10m) + 2(1mx5m) + 2(10mx5m)
s = (2 x 10m) + (2 x 5m) + (2 x 50m)
s = 20m + 10m + 100m
s = 30m + 100m
s = 130m^2
answer= 4th option
3.
s = 2(bh/2) + hw + sw + bw
s = 2(3ftx2ft/2) + (2ftx5ft) + (4ftx5ft) + (3ftx5ft)
s = 2(6ft/2) + 10ft + 20ft + 15ft
s = 2 x 3ft + 10ft + 35ft
s = 6ft + 45ft
s = 51ft^2
answer= 2nd option
4.
s = 6a^2
s = 6 x 2mm^2
s = 6 x 4mm
s = 24mm^2
answer= 3rd option

s = 6a^2
