Answer:
x = -3, -5.
Step-by-step explanation:
(2x + 8)/6 = 1/3(x + 4)
Cross multiply:
(2x + 8)(x + 4) = 6 * 1/3
(2x + 8)(x + 4) = 2
2x^2 + 16x + 32 - 2 = 0
2x^2 + 16x + 30 = 0
x^2 + 8x + 15 = 0
(x + 3)(x + 5) = 0
x = -3, -5.
1 km = 1,000 m
1 m = 1,000 mm
therefore
1 km = 1,000 m = 1,000 · 1,000 mm = 1,000,000 mm
2 km = 2,000,000 mm > 3,000 mm
Answer: 3,000 mm is less than 2 km.

3x - 4y = 9 and 2x + 3y = 7, which of the following would be the best method?
Answer: x = 40
Step-by-step explanation:
4= x/-4 + 14 Remember that in front of every variable there is a number 1.
4 = - 1/4x + 14 subtract 14 from both sides
-14 -14
-10 = -1/4x Divide both sides by -1/4
x = 40
