Answer:

C. 9p + 1

Step-by-step explanation:

2(4p - 3) + (p + 7)

Step 1:  Distribute 2 in the first term to both terms in the parenthesis.  You can drop the parenthesis on the second term (p + 7)...

2(4p) + 2(-3)  + p + 7      

Now multiply

8p - 6 + p + 7

Now simplify by combining like terms

8p + p -6 + 7

   9p + 1            (8p + p = 9p, -6 + 7 = 1)

A family owns two businesses that made a combined profit of $$$10 million in the previous financial year, with business B making
Archy [21]

Answer:

The equation to find the profit made by business combined is x+4x = 10.

Business A made $2 million profit and Business B made $8 million profit.

Step-by-step explanation:

Given:

Profit made in previous financial year = $10 million

We need to write an equation to find the profit made by the business.

Solution:

Let the profit (in millions) made by  business A be 'x'.

Let the profit (in millions) made by  business B be 'y'.

Now given:

business B making 4 times as much profit as business A.

so we can say that;

y =4x

Now we know that;

Profit made in previous financial year is equal to sum of profit (in millions) made by  business A and profit (in millions) made by  business B.

framing in equation form we get;

x+y =10\ million

Substituting the value of y in above equation we get;

x+4x = 10

Hence The equation to find the profit made by business combined is x+4x = 10.

On Solving above equation we get;

5x =10\\\\x =\frac{10}{5} = \$2 \ million

profit (in millions) made by  business A = \$2 \ million

profit (in millions) made by  business B = 4x =4\times 2 =\$8 \ million

Hence Business A made $2 million profit and Business B made $8 million profit.

Answer:

<u>greater than what it was before</u>

Step-by-step explanation:

<em>Remember</em>, a tornado usually causes significant structural damages to houses within its area of impact., and this requires running expenses to repair the damage.

Hence,<u> since the term </u><u>expenditure, </u><u>also implies expenses; we can expect the total expenditure on housing after the tornado to be </u><u>greater than</u><u> what it was before the tornado since families would be paying for repairs.</u>
