The number that is divided is called the dividend and the number which the dividend is being divided by is the divisor. The answer to a division problem is the quotient.

In the given question 2 10 1 5 is being divided by -5

So 2 10 1 5 represent the dividend .These numbers are the coefficients of the constants which are arranged in descending order.The dividend can be written as :

$2x^{3} +10x^{2} +x+5$

The second option is the right answer.

Daniel [21]

Using the together rate, it is found that it would take them 16 hours to sew 12 dresses.

<h3>What is the together rate?</h3>

The together rate is the <u>sum of each separate rate</u>.

In this problem, we have that:

Vera's rate is of 1/2.

Ivy's rate is of 1/4.

Hence, the together rate is the time it would take them to produce one dress working together, and is given by:

$\frac{1}{x} = \frac{1}{2} + \frac{1}{4}$

$\frac{1}{x} = \frac{2 + 1}{4}$

$3x = 4$

$x = \frac{4}{3}$

Then one dress takes $\frac{4}{3}$ of an hour, and the time for twelve dresses is:

$t = 12 \times \frac{4}{3} = 4(4) = 16$

It would take them 16 hours to sew 12 dresses.

Answer:

The sum of money received by Ali, Carrie and Bryan is $ 740.

Step-by-step explanation:

At first we translate mathematically each sentence:

(i) <em>Ali, Carrie and Bryan received a sum of money. </em>

$a$ - Ali's money.

$b$ - Bryan's money.

$c$ - Carrie's money.

(ii) <em>Bryan's money was </em> $\frac{3}{5}$ <em> of Ali's money</em>.

$b = \frac{3}{5}\cdot a$ (1)

(iii) <em>The ratio of Ali's money to Carrie's money was 4 : 1</em>.

$\frac{a}{c} = 4$ (2)

(iv) <em>Ali had $ 160 more than Bryan</em>.

$a = b + 160$ (3)

After some algebraic handling, we have the following system of linear equations:

$3\cdot a - 5 \cdot b = 0$ (1b)

$a - 4\cdot c = 0$ (2b)

$a - b = 160$ (3b)

The solution of the system is: $a = 400$ , $b = 240$ , $c = 100$

The sum of money is:

$s = a + b + c$

$s = 740$

The sum of money received by Ali, Carrie and Bryan is $ 740.
