In the equation 5x/y = z, what is the value of z if x is 7 and y is 4?

The correct answer is: 21

In this equation, the value of z represents the quotient when 5 times x is divided by y. In order to find the value of z, we can substitute the given values for x and y into the equation and solve for z. By substituting 7 for x and 4 for y, we get 5(7)/4 = z 35/4 = z z = 8.75 Option A (1.7) is incorrect because it is the result of dividing 7 by 4, which is not what the equation is asking for. Option C (3.5) is incorrect because it is the result of dividing 5 by 4, which is also not what the equation is asking for. Option D (35) is incorrect because it represents multiplying 7 by 5, rather than dividing
