Step-by-step explanation:
(a)
To change a mixed number to an improper fraction
Multiply the whole number by the denominator of the fraction and add the numerator. This value is the numerator of the improper fraction while the denominator remains unchanged, that is
(2 × 13) + 12 = 26 + 12 = 38 ← numerator
2 =
(b)
To change an improper fraction to a mixed number
divide the numerator by the denominator, noting the remainder, which forms the numerator of the fraction in the mixed number.
= 2 remainder 9, hence
= 2
Answer:
The table in the exercise can be completed with the next results:
- x y
- 2 <u>9</u>
- 4 <u>11</u>
- 6 <u>13</u>
- 8 <u>15</u>
Step-by-step explanation:
As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:
- y = x + 7
Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:
When x is 2:
- y = 2 + 7
- <u>y = 9</u>
When x is 4:
- y = 4 + 7
- <u>y = 11</u>
When x is 6:
- y = 6 + 7
- <u>y = 13</u>
When x is 8:
- y = 8 + 7
- <u>y = 15</u>
At last, <u>to obtain the graph you can use the formula made: y = x + 7</u>, and you'll obtain a graph like the attached picture, <em>where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7</em>.
