Answer:
169 is the answer.
Step-by-step explanation:
I used a calculator.
I'm assuming that you are trying to solve the equation for y, which we can do by isolating the variable on one side of the equation.
y/7 = 4
To get rid of the denominator of y, we have to multiply both sides by this amount (7).
(y/7)*(7) = (4)(7)
When we simplify, we get:
y = 28
If we go back to the original equation and plug in our answer, 28/7 = 4, we can see that it results in a true statement.
Therefore, the answer is y=28.

Answer:
1/7
Step-by-step explanation:
Formula for 2 perpendicular lines: m1 * m2 = -1,
where m1 is gradient of 1st line and m2 is gradient of 2nd line
Application:
-7 * m2 = -1
m2 = 1/7
