Answer:
36.7 or 110/3
Explanation:
The question ask you to find the sum of the value of 1/3x and 7x when the value of x = 5.
Find 1/3x + 7x when x= 5
This means 5 will replace x in the equation 1/3x + 7x.
Therefore, in the equation below x will be replaced by 5
1/3x + 7x = ?
1/3x + 7x = ? when x = 5
1/3 × 5 + 7 × 5 = ?
5/3 + 35 = (5 + 105) / 3
110/3 = 36.666 ≈ 36. 7
36.7
