Answer:
The answer is 70
Step-by-step explanation:
Just add 40 and 30 and you'll get your answer
To find the value of y, set up an equation where y + (-30) = 40. Solve for y by isolating it on one side of the equation.
To solve this problem, we can set up an equation using the information given. Let's represent the unknown number, which is the sum of y and -30, as x. We can write the equation x = 40. To find the value of x, we'll need to isolate it by performing the opposite operation of adding -30, which is adding 30 to both sides of the equation. This gives us x + 30 = 70. Finally, subtracting 30 from both sides gives us x = 70.

Answer:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Step-by-step explanation:
Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
