Answer:

$\boxed{\sf{96x-70}}}$

Step-by-step explanation:

Use the distributive property.

<h3>What is a distributive property?</h3>

Distributive property is a serving to distribute or allot or disperse.

Distributive property:

A(B+C)=AB+AC

A(B-C)=AB-AC

-10(1-9x)+6(x-10)

Expand.

-10(1-9x)

-10*1=-10

-10*9x=90x

$\longrightarrow \sf{=-10+90x+6\left(x-10\right)}}$

6(x-10)

6*x=6x

6*10=60

6x-60

Rewrite the problem down.

= -10+90x+6x-60

Combine like terms.

90x+6x-10-60

Add the numbers from left to right.

90x+6x=96x

96x-10-60

Finally, subtract the numbers from left to right.

-10-60=-70

$\Longrightarrow \boxed{\sf{96x-70}}$

Therefore, the final answer is 96x-70.

I hope this helps, let me know if you have any questions.

Little Book LTD has total assets of $860 000. There are 75 000 shares of stock outstanding, total book value of $750 000 with a

Lyrx [107]

a) Little book LTD earning per share is $1.118 per share.

Explanation:

To calculate earning per share we will use following formula: $\frac{NET INCOME}{WEIGHTED AVERAGE SHARE OUTSTANDING}$

Now to find net income we will take help of asset turnover ratio : $\frac{NET SALES}{TOTAL ASSET}$

NOTE : LET x BE THE NET SALES DURING THE YEAR.

Asset turnover ratio = $\frac{x}{860000}$

1.5 × $860000 = x

x (net sales) = $1290000

Outstanding shares = 75000 shares

So Net Income = $1290000×.065

= $83850

Now Earning per share = $\frac{83850}{75000}$

Earning per share = $1.118

b) Market to Book Ratio will be 1.2 for Little Book LTD.

Explanation:

Market to Book Ratio = $\frac{MARKET CAPITALIZATION}{TOTAL BOOK VALUE}$

Market Capitalization = $ 75000× $ 12

= $900000

So, Market To Book Ratio = $\frac{900000}{750000}$ = 1.2

So , Market To Book Ratio is 1.2 for little book ltd.

Debora [2.8K]

Step-by-step explanation:

Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 15 gallons of fuel, the airplane weighs 2187 pounds. When carrying 35 gallons of fuel, it weighs 2303 pounds. How much does the airplane weigh if it is carrying 50 gallons of fuel?

----

You have two points relating fuel and weight.

(15,2187) and (35,2303)

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

slope = (2303-2187)/(35-15) = 5.8

----

intercept = ?

2187 = 5.8*15 + b

b = 2100

-------

Equation:

f(x) = 5.8x + 2100

---

f(50) = 2390 lbs.
