Answer:
x>−7
Step-by-step explanation:
left side:
-8(x-3)+5x
distribute -8 into (x-3)
-8x+24+5x
combine like terms
-3x+24
right side:
9(x+12)
distribute 9 into (x+12)
9x+108
-3x+24<9x+108
Subtract 24 on both sides
-3x< 9x+108-24
combine like terms
-3x<9x+84
Subtract 9x on both sides
-3x-9x<+84
combine like terms again
-12x<84
Multiply both sides by -1 (reverse the inequality)
(-12x)(-1)>84(-1)
12x>-84
divide both sides with 12

x>−7

(87+91+86+x)/4=90.
x=96.

50×y > 130.
the lowest number could be 3, because 50×2=120, which is less than 130.
Answer:
A) 96 cm
Step-by-step explanation:
Split into three parallelograms
Shape 1: 6 by 7 6×7=42
Shape 2: 3 by 4 3×4=12
Shape 3: 6 by 7 6×7=42
42+12+42=96
Answer:Divide both sides by the numeric factor on the left side, then solve.
