Answer:

44 hours

Step-by-step explanation:

13.50 × 35 = 472.5

675 - 472.5 = 184.5

184.5 ÷ 20.25 = 9.1

9.1 + 35 = 44.1

rounded to 44

Answer:

JoAnn worked for the week = 45 hours

Step-by-step explanation:

JoAnn paid $13.50 an hour for the first 35 hours each week.

$20.25 each hour after 35 hours.

The equation is

35*13.50 +20.25x = 675, where "x" represents the number of hours she worked after 35 hours.

472.50 + 20.25x = 675

20.25x = 675 - 472.50

20.25x = 202.50

x = 202.50/20.25

x = 10

JoAnn worked for the week = 35 + 10 hours

JoAnn worked for the week = 45 hours.

That's the answer.

Hope you will understand the concept.

Thank you.

Correct I’ll give brainlist no links or I’ll report
Gwar [14]

Alright, to start, slope-intercept form is y=mx+b, where m is the rate is it going up/down by, and b is the starting point.

With this, the question says that Coraz started with 0 naxvips then purchased 10 each month afterwards.

From this, we can fill in the equation, using m as the rate it is going up/down and b as the starting point:

<h3>The Equation: </h3>

y=10x+0

Next, it wants a table, so let's use the equation created to do this. X is the amount of months that have gone by, deciding how many naxvips Coraz has purchased.

So, to start, lets plug in 0 months into the equation into x:

y=10(0)+0

y=0+0

y=0

The answer resulted in 0 for month 0, understandably. Month 0 was when it said Coraz had 0 naxvips on his farms. With this, it would be (0,0) for this part.

For the next month, same thing, just plug it in:

y=10(1)+0

y=10+0

y=10

The answer resulted in 10 for month 1. Month 1 was when it said Coraz purchased his first batch of 10 naxvips. With this, it would be (1,10) for this part.

Again, with 2 months

y=10(2)+0

y=10+0

y=20

The answer resulted in 20 for month 2. Month 2 was when he got another 10 naxvips. With this, it would be (2,10) for this part. However, see the pattern? For every month, there will be 10 more naxvips added. With this, we can write out the table for it as well:

<h3>The Table:</h3>

(X, Y)

0, 0

1, 10

2, 20

3, 30

4, 40

etc..

Find the sum of the terms.
kow [346]

Answer:

C

Step-by-step explanation:

Given

\frac{x}{x^2+3x+2} + \frac{3}{x+1} ← factor the denominator of first fraction

= \frac{x}{(x+1)(x+2)} + \frac{3}{x+1}

Multiply the numerator/ denominator of second fraction by (x + 2)

= \frac{x}{(x+1)(x+2)} + \frac{3(x+2)}{(x+1)(x+2)}

The denominators are now common, so add the numerators leaving the denominator, that is

= \frac{x+3x+6}{(x+1)(x+2)}

= \frac{4x+6}{(x+1)(x+2)} → with numerator 4x + 6 → C
