Hey!

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

Solution:

= 4(x + 3) - 1

= 4x + 12 - 1

= 4x + 11

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

Answer:

Jesse was on the right track at the beginning but she didn't use distributive property correctly. What she need to do was multiply 4 * x and 4 * 3 but she only did 4 * x.

Alex787 [66]

Answer:

It will take 5 hours and 5 minutes to fill the tank

Step-by-step explanation:

Here, we want to get the time taken to fill the tap

Let us have the rate per hour

A fills in 6 hours; so the fraction filled in an hour is 1/6

B fills in 8 hours, so the fraction filled in an hour is 1/8

C empties in 10 hours, so the fraction removed per hour is 1/10

So factoring the supply and removal, where removal is on a negative basis

we have it that in an hour, the fraction retained is;

1/6 + 1/8 - 1/10

= (20 + 15 - 12)/120

= 23/120

So this is the fraction retained per hour

The number of hours it will take to have a whole is simply the reciprocal of this fraction

That would simply be 120/23 = 5 5/23

5 hours and 5 minutes

At the beginning of the year, Mr. and Mrs. Smith's portfolio is made up of $200 cash, stocks, with value of $236,000, and bonds
mart [117]

Answer:

4.797% of total return

Step-by-step explanation:

In this case, first, let's gather the data:

Beggining of the year:

200 + 236,000 + 163,000 = 399,200$

End of the year:

200 + 250,000 + 159,000 = 409,200$

This means that between the beggining and the end of the year, Mr Smith only had a gain of 10,000$.

To get the final return, we need to add this gain to the dividens and interest which is:

10,000 + 5,000 + 4,150 = 19,150$

So, the total return would be the percentage between this gaining and the innitial amount:

% = 19,150 / 399,200 * 100

% = 4.797%

And this is the total return.
