If (10x / 23) = 8/5 and 6y/7 = 3/10, then what is the value of x + y?

Rationale

x + y equals 4.08.

To solve the equations provided, we find the values of x and y separately and then sum them. By solving for both variables, we discover that their sum is 4.08.

A (4.38) YOUR ANSWER

This choice results from incorrect calculations of x and y. The value of x is determined to be 2.3 and y to be 1.8, leading to a sum of 4.1, not 4.38.

B (4.28) YOUR ANSWER

This option is also incorrect as it suggests a miscalculation in either x or y's value. Correctly computed, x is approximately 2.3 and y approximately 1.8, resulting in a total of 4.1, which does not match this choice.

C (4.23) YOUR ANSWER

This choice indicates an underestimation of the individual values of x and y. The accurate values derived from the equations yield a sum of 4.1, which is less than the proposed 4.23.

D (4.08) CORRECT

This is the accurate value derived from the correct computations for x and y, where x equals 2.3 and y equals 1.8, resulting in a sum of 4.08.

E (4.03) YOUR ANSWER

This choice reflects an incorrect total derived from miscalculating the individual values of x and y. With the correct values being 2.3 and 1.8, the sum is 4.1, not 4.03.

Conclusion

To find the value of x + y, we solved the equations individually, discovering x = 2.3 and y = 1.8, leading to a total of 4.08. All other options represent errors in calculation or assumptions about the values of x and y, reinforcing the necessity of careful arithmetic when solving algebraic equations.

If (10x / 23) = 8/5 and 6y/7 = 3/10, then what is the value of x + y?

x + y equals 4.08.
