Answer:
O 9.25
Explanation:
The following mathematical equation is given in this question:
5x + 2y = 20
Using this equation, we're asked to find the value of y when x = 0.3. Hence, we substitute 0.3 for x in the equation as follows:
5x + 2y = 20
5 (0.3) + 2y = 20
1.5 + 2y = 20
Collect like terms
2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
y = 18.5/2
y = 9.25
Therefore, y = 9.25 when x = 0.3
