Answer:

Step-by-step explanation:

Hmmm.... it looks like your missing part of the question. Since it's not there, I cannot fully answer your question, but I can tell you that a composite number is a number that has more than one divisors/factors.

Here are some examples of composite numbers:

4 - is divisible by 2 and 1

6 - is divisible by 2, 3, and 1

8 - is divisible by 2 and 1 (also four, but four can be broken down into 2's.)

e. Translate the word problem below into an equation; then solve. It only takes Vera 2 hours to sew 1 dress, but it takes Ivy 4

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.

The coffee merchant plans to mix some fancy $6.50 per pound ground coffee called royal soil with 10 pounds of a lowly $2 per pou

taurus [48]

Answer and explanation:

Given:

Royal soil= $6.50 per pound

Royal peasant = $2 per pound of 10 pounds

Blend total pounds is x+10, price is unknown hence solved below

Using algebra

We find unknown x = number of pounds of royal soil

$6.50(x)+$2(10)=6.50x+20/x+10(x+10)

= 6.50x+20= 6.50x²+85x+200

Christine is 4 years younger than Mark. 3 years from now, she will be two-thirds as old as Mark find their present ages.Complete

icang [17]

Answer:Mark Is 9 years old; Christine is 5 years old

Step-by-step explanation:

Present age

LET mark age be x

Christine be x-4 yrs

In 3 yrs Time

Mark will be x+3 yrs old

Christine will be (x -4 +3) = x-1 years old

Also, In 3 years time

Christine = 2/3 Mark

such that

x-1 = 2/3(x+3)

x -1= 2x+6 / 3

3x -3= 2x+6

3X--2X = 6+3

=X=9

Mark Is 9 years old

Christine is x -4 = 9-4=5 years old
