Help me solve this pls

Answer:

$\frac{x - 10}{8}$

Step-by-step explanation:

$\frac{3x}{8} - \frac{x + 5}{4}$

The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.

Thus:

$\frac{1(3x) - 2(x + 5)}{8}$

$\frac{3x - 2x - 10}{8}$

$\frac{x - 10}{8}$

An item sells for $30 and is on sale for 15% off and the sales tax is 8.2%. What is the final cost to the nearest cent?

Ronch [10]

Answer:

$27.59

Step-by-step explanation:

1) First we calculate the sales tax:

30 x .15 = 4.5

30 - 4.5 = 25.5

2) Now we calculate sales tax

25.5 x .082 = 2.09

25.5 + 2.09 = $27.59

2m+n=7<br> 4m+3n=-10<br> Solve using substitution method

jeka57 [31]

Answer:

m=31/2, n=-24. (31/2, -24).

Step-by-step explanation:

2m+n=7

4m+3n=-10

-------------------

n=7-2m

4m+3(7-2m)=-10

4m+21-6m=-10

-2m=-10-21

-2m=-31

2m=31

m=31/2

2(31/2)+n=7

31+n=7

n=7-31

n=-24

Ron and Freddy built structures out of snap cubes. Ron's tower had an 8-inch square base. Freddy had a 6-inch square base. If Ro

Sphinxa [80]

Answer: Ron tower's

Step-by-step explanation:

Given

Ron tower has a base of $A_r=8\ in.^2$

Freddy tower has a base of $A_f=6\ in.^2$

Suppose the tower is in the shape of a square prism

The volume of Ron and Freddy tower is $320\ \text{and}\ 180\ in.^3$

The volume of a square-based prism is $V=\frac{1}{3}a^2h$

$\therefore \text{height of Ron tower is}\ h_r=\dfrac{3V}{A_r}\\\\\Rightarrow h_r=\dfrac{3\times 320}{8}=120\ in.$

The height of Freddy tower is

$\Rightarrow h_f=\dfrac{3V}{A_f}\\\\\Rightarrow h_f=\dfrac{3\times 180}{6}=90\ in.$

Thus, the height of Ron's tower is more than Freddy's tower by $30\ in.$
