Answer:
x - 8 ≤ 4
+8 +8 Add eight to both sides of the equation.
X≤12
2x + 3 > 9
-3 -3 Subtract three from both sides
2x>6 Divide both sides by 2
x>3
Hope this helps!
Have an amazing day/night!
Answer: 28 cm
Step-by-step explanation:
x - the length of the shorter piece
2x - the length of the longer piece
Together they are 42 cm long.
Compose te equation:
2x + x = 42
3x = 42
x = 14 cm
The shorter piece is 14 cm, the longer piece is twice longer, 2x, or 2( 14 ).
Two times longer than 14 is 28. The longer piece is 28 cm.
Answer:
x = 1
Step-by-step explanation:
2x+4=8x-2
2x - 8x = -4 -2
-6x = -6
x = 1
Answer:

Answer: 11/10 or 1 1/10 pages
Step-by-step explanation:
3/5 + 1/2 = x
find the LCD so that you can add the fractions.
3/5 (2/2) = 6/10
1/2 (5/5) 5/10
6/10 + 5/10 = 11/10 or 1 1/10
