Answer:
7/3

Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.

We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.

Another way to calculate the slope of the line is the use this formula:

(y2-y1)/(x2-x1)

The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:

(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)

When we simply the fraction, we would get 7/3 and that would give us the slope.

I hope this helps!

soldier1979 [14.2K]

Answer:

$\frac{9}{20}$ students.

Step-by-step explanation:

We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.

To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:

$\text{Students who play a sport and a part of the drama club}=\frac{6}{8}\times \frac{3}{5}$

$\text{Students who play a sport and a part of the drama club}=\frac{3}{4}\times \frac{3}{5}$

$\text{Students who play a sport and a part of the drama club}=\frac{3\times 3}{4\times 5}$

$\text{Students who play a sport and a part of the drama club}=\frac{9}{20}$

Therefore, $\frac{9}{20}$ students play sport and part of the drama club.

Marysya12 [62]

Answer:

$1260

Step-by-step explanation:

Given data

You make $2,800 per month

Rent= 30% of monthly earning

=30/100*2800

= 0.3*2800

=$840

Transportation and foodt= 15% of monthly earning

=15/100*2800

= 0.15*2800

=$420

Hence the total expenses = 840+420

= $1260

Select the best answer for the question

JulijaS [17]

The answer is A. To add fractions, the denominator has to be the same. What number do 9 and 3 share when multiplying ? It is 9.

So multiply 2/3 by 3/3 to get 6/9. And 1/9 by 1/1 to get 1/9. Now add 6/9 with 1/9 which is 7/9

Now add 7/9 with 5/18. 9 and 18 share 18. Multiply 7/9 by 2/2 which is 14/9. Add 14/9 to 5/18 which is 19/18
