Adding and Subtracting Fractions say the question number and answer 1. 2/4 + 1/4 =

2. 1/2 + 1/4 =

3. 3/10 + 6/10 =

4. 4/6 - 1/6 =

5. 8/12 + 1/4 =

6. 5/7 - 3/7 =

7. 20/24 - 1/4 =

8. 9/10 - 4/5 =

9. 2/3 + 1/6 =

10. 18/22 - 6/11 =

Choose some that you can do if you cant figure one out someone else can do the question

1)3/4

2)3/4

3)9/10

4)1/2

5)11/12

6)2/7

7)7/12

8)1/10

9)5/6

10)3/11

Step-by-step explanation:

1. 2/4+1/4=3/4

2. 1/2+1/4 2/4+1/4=3/4

3/10+6/10=9/10

4/6-1/6=3/6 or 1/2

5 8/12+1/4 8/12+3/12=11/12

6 5/7-3/7=2/7

7 20/24-1/4 20/24-6/24=7/12

8 9/10-4/5 9/10-8/10=1/10

9 2/3+1/6 4/6+1/6=5/6

10 18/22-6/11 18/22-12/22=3/11

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
