1 answer:

8 0

The answer is -4/7
First, you distribute the -3 and -5 through the parentheses.
-6x+6-15x-15=3
Then combine like terms
-21x-9=3
Do opposite operation
9+3=12
That leaves
-21x=12
Divide both side by -21
X= -4/7

Bill bought a computer and a printer for a total of $650.

Let p stand for the cost of the printer, so

$\text{Cost of the computer + p} =650$

$\Rightarrow 525+p=650$

$\Rightarrow p=650-525=125$

Bonnie ordered 27 products from one company

Let m stand for the number of missing items

$\text{Number of item she got + m} =27$

$\Rightarrow 19+m=27$

$\Rightarrow m=27-19=8$

Terri bought four lipsticks for a total cost of $20

Each survey takes him about 10 minutes to complete

Let h stand for the number of hours

$Tota\l time\ taken\ = Time\ taken\ for\ 1\ survey\ in\ hours\times no.\ of\ survey$

Claire is saving up to buy a new laptop that costs $849. She has $232 and is saving $28 each week. How many full weeks will it t

miss Akunina [59]

Subtract the amount she has saved from the price of the laptop:

849 - 232 = 617

Now divide the amount she still needs by the amount she saves per week:

617 / 28 = 22.04

Because the answer has a number to the right of the decimal, she will need to save for 23 full weeks to have enough money.

If she saves for 22 weeks, she would be $1 short:

22 x 28 = 616 + 232 = 848

A shelter has enough food to feed an average of 80 hungry people a day for 14 days. If an average of 32 people are at the shelte

Katen [24]

Answer:

<u>35 days. </u>

Explanation

The capacity of the shelter is a constant. It is 80 people × 14 days.

That is an inverse relation: the product of the number of people and the number of days will be always the same.

As the number of people decreases the number of days that the food lasts increases, in a proportion such that the product of the days and the number of people is the same.

Thus, for 32 people the number of days the food lasts is x, such that:

32 people × x = 80 people × 14 days

Solving for x:

x = 80 people × 14 days / 32 people

x = 35 days ← answer

The food will last 35 days.
