Find and solve the equation for the value of n (by finding the value of n, you are finding which value of n that makes the statement true.)

3.74 = 0.4n + 2.5

3.74 - 2.5 = 0.4n

1.24 = 0.4n

n = 3.1

So the value of n which makes the statement true is 3.1

Hope this helps :)

mrs. fuentes earns a salary of 60,000. ms. williams earns a salary of 51,000. mrs fuentes will receive a salary increase of 1,52

BlackZzzverrR [31]

Answer:

( $2,525 - $1,525)x = $9,000

Step-by-step explanation:

Data provided:

Salary earned by Mrs. Fuentes = $60,000

Salary earned by Ms. Williams = $51,000

Increase in salary of Mrs Fuentes = $1,525 per year

Increase in salary of Ms Williams = $2,525 per year

since, x is the number of years after which their salary will be equal

Now,

Total salary of Mrs. Fuentes after x years = $60,000 + $1,525x

and,

Total salary of Ms. Williams after x years = $51,000 + $2,525x

also,

when their salaries are equal

$60,000 + $1,525x = $51,000 + $2,525x

$2,525x - $1,525x = $60,000 - $51,000

( $2,525 - $1,525)x = $9,000

What is the sum of the fractions? Use the number line and equivalent fractions to help find the answer.

Alchen [17]

<h3>Answer: -3/4 (choice C)</h3>

==================================================

Explanation:

Think of a whole cake or pizza. Now slice it into 4 equal pieces. This represents 1 is the same as 4/4.

Adding on another quarter slice gets us 4/4+1/4 = 5/4

In other words, the mixed number 1 & 1/4 is the same as the improper fraction 5/4.

So 1 & 1/4 = 5/4

This then means -1 & 1/4 = -5/4 because we multiply both sides by -1.

Now we'll add on 1/2, which is the same as 2/4, like so

(-1 & 1/4) + 1/2

-(1 & 1/4) + 2/4

-(1 + 1/4) + 2/4

-1 - 1/4 + 2/4

-1 + (-1/4 + 2/4)

-1 + 1/4

-4/4 + 1/4

-3/4

which points us to choice C as our final answer

Notice how if we started at -5/4, and moved to the right 2 tickmarks, we arrive at -3/4. Each tickmark represents 1/4 of a unit, so two of them is 2/4 = 1/2.

Side note: -3/4 converts to the decimal -0.75

Maggie wants to buy 4 roses , 6 carnations, and 9 tulips . She estimates that she will spend about $14 on these flowers. Do you

Andrew [12]

Well, 4 + 6 + 9 = 19, so $14 is a reasonable answer. If we have $19 assuming that each flower costs $1, then if the estimate is $14, that means that each flower is less than $1, which makes sense. Assuming that all of the flowers cost the same, then each flower would be about 74 cents. This would make sense considering that you are buying tulips, roses, and carnations. I really hope this helps; if not, good luck on your homework.
