890
Step-by-step explanation:
Let's assume the two students each scored an unknown x marks. The total of the 2 students will be x + x = 2x
We’ll add the 2x to the total of the three (3) students. Therefore the total for all five (5) students it will be;
78 + 82 + 85 + 2x
Their mean is 405. Therefore;
(78 + 82 + 85 + 2x) / 5 = 405
Lets solve the equation now;
245 + 2x = 405 * 5
2x = 2025 – 245
2x = 1780
X = 1780 / 2
X = 890

Step-by-step explanation:
<u>Step 1: Define Equation</u>
8x - 3 = 2(x - 1/2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distributive 2: 8x - 3 = 2x - 1
- Subtract 2x on both sides: 6x - 3 = -1
- Add 3 to both sides: 6x = 2
- Divide 6 on both sides: x = 1/3
