Answer:

3

Step-by-step explanation:

Given 2 3/4 + 1/3

First change the mixed fraction to improper fraction .

That’s 2 2/3 becomes 8/3. Multiply the denominator 3 by the whole number 2 and then add it the numerator 3.

Now we have 8/3 + 1/3 .

We look for the lowest common multiple LCM of the denominators of the fractions.

The LCM is = 3

Now divide the denominator of each fraction by the LCM 3 and multiply the result by the numerator.

We have 8 + 1 /3 .

Everything divided by the LCM.

8 + 1 /3

9/3

3/1

Construct a linear equation for the linear data presented in the table
yaroslaw [1]

Answer:

y = -7x

Explanation:

Take two points from table: (-4, 28), (-3, 21)

Find slope:

\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\rightarrow \sf slope\ (m):   \dfrac{21-28}{-3-(-4)}  = -7

Now find equation:

\sf y - y_1 = m (x - x_1)

\rightarrow \sf y - 21 = -7(x - (-3))

\rightarrow \sf y  = -7(x +3) + 21

\rightarrow \sf y  = -7x -21 + 21

\rightarrow \sf y  = -7x

natulia [17]

Answer:

3

Step-by-step explanation:

Given

15 gold ribbons

22 blue ribbons

53 red ribbons

Total of 53 + 22 + 15 = 90 ribbons

Total number of students = 12 boys + 18 girls = 30 students.

If evenly divided, each student will have 90/30 = 3 ribbons

The expression to solve would basically be the amalgamation of what we did above:

(53 + 22 + 15)/(12+18)
