10\frac{3}{4}-4\frac{7}{8}

To simplify, write each mixed number as a proper fraction.

To write a mixed number as a proper fraction add the whole part and the fraction part.

Addition and substraction of fractions:

\frac{a}{b}\pm\frac{c}{d}=\frac{ad\pm bc}{bd}

Write 10 3/4 as a porper fraction:

10+\frac{3}{4}=\frac{40+3}{4}=\frac{43}{4}

Write 4 7/8 as a proper fraction:

4+\frac{7}{8}=\frac{32+7}{8}=\frac{39}{8}

Then, you have the next substraction of fractions:

undefined

7.5 %

Step-by-step explanation:

We by finding how far from the mean the 999 volume caps are, using z score;

Z = (x – μ) / σ

Z = (999 – 998) / 7

Z = 0.143    

We use the z-table to find the confidence levels;

= 85%

= 0.85

Since we are finding proportion of bottles have volumes greater than 999

mL;

1 – .85 = .15

0.15/2 = 0.075

= 7.5%

20=8+v i dont know how to do this
Tasya [4]
20 = 8 + v equals v = 12.

First,  subtract 8 from both sides. Your problem should look like: 20 - 8 = v
Second,  simplify 20 - 8 to get 12. Your problem should look like: 12 = v.
Third, switch sides to get v = 12, which is the correct answer.
