Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
b)
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 7
Answer:
1733.28 m³ or approximately 1733 m³
Step-by-step explanation:
Cone - 1/3πr²h
Cylinder - πr²h
Cone - 1/3(3.14)(6)²(10) ⇒ 376.8
Cylinder - (3.14)(6)²(12) ⇒ 1356.48
1356.48 + 376.8 = 1733.28 m³
Approximately 1733 m³
If you would like to solve 1/4 * 4/7, you can do this using the following steps:
<span>1/4 * 4/7 = (1 * 4) / (4 * 7) = 4/28 = 1/7
</span>
The correct result would be 1/7.
