Answer:

Shale is composed of small particles of clay. It's grain size is not visible, soft, and is generally impermeable.

Sandstone is composed of well-sorted sand-size quartz grains. It is very hard, the grain is visible.

Conglomerate is composed of assorted grain sizes. It's very poorly sorted and can be composed of more than one mineral and rock type.

I hope this helps.

Answer/Explanation:

We would solve for the value of x in each case.

1. $4x = 12$

$x = \frac{12}{4}$ (division property of equality)

$x = 3$

2. $\frac{x}{14} = -7$

$x = -7 \times 14$ (multiplication property of equality)

$x = -98$

3. $26 = 14 + x$

$26 - 14 = x$ (subtraction property of equality)

$12 = x$

$x = 12$

4. $-2 + x = 7$

$x = 7 + 2$ (addition property of equality)

$x = 9$

5. $x - 6 = -2$

$x = -2 + 6$ (addition property of equality)

$x = 4$

6. $- 5 = \frac{x}{8}$

$- 5 \times 8 = x$ (multiplication property of equality)

$-40 = x$

7. $- 7 = x + 3$

$- 7 - 3 = x$ (subtraction property of equality)

$-10 = x$

$x = -10$

8. $-6x = 42$

$x = \frac{42}{-6}$ (division property of equality)

$x = -7$

9. $\frac{x}{6} = 4$

$x = 4 \times 6$ (multiplication property of equality)

$x = 24$

10. $13 = x - 4$

$13 + 4 = x$ (addition property of equality)

$17 = x$

$x = 17$

11. $100 = -25x$

$\frac{100}{-25} = x$ (division property of equality)

$-4 = x$

$x = -4$

12. $-7 + x = 4$

$x = 4 + 7$ (subtraction property of equality)

$x = 11$

13. $7 + x = 37$

$x = 37 - 7$ (subtraction property of equality)

$x = 30$

14. $56 = 8x$

$\frac{56}{8} = x$ (division property of equality)

$7 = x$

$x = 7$

15. $\frac{x}{1} = -18$

$x = -18$ (multiplication property of equality)

$x = -18$

16. $x + 6 = 16$

$x = 16 - 6$ (subtraction property of equality)

$x = 10$

17. $x - 1 = -1$

$x = -1 + 1$ (subtraction property of equality)

$x = 0$

18. $10x = 70$

$x = \frac{70}{10}$ (division property of equality)

$x = 7$

19. $-11 = \frac{x}{3}$

$-11 \times 3 = x$ (multiplication property of equality)

$x = -33$

20. $x - 5 = 1$

$x = 1 + 5$ (addition property of equality)

$x = 6$

If Sam invested $3,000 and he earned $300 over six months, the return is _____.

a_sh-v [17]

<span>The APR would be 20%. This would yield Sam $600 in a year, so he would earn $300 in six months as long as the interest was non compounding. The interest rate is multiplied by the amount of principal, and then multiplied by the amount of time. In this case the time is 6/12.</span>
