<u><em>The correct question is</em></u>
Solve the following equation for d. Be sure to take into account whether a letter is capitalized or not.
we have
Solve for d
That means -----> isolate the variable d
Subtract 4 both sides
Multiply by d both sides
Divide by (5n-4) both sides
Answer:
140
Step-by-step explanation:
Rewording the problem will make it easier to write the equation you need to solve this. Think of it in simpler terms: "7 is 5% of how many?". "7" is just a 7; the word "is" means =; "5%" is expressed as its decimal equivalency (.05); the word "of" means to multiply; and "how many" is our unknown (x). Putting that all together in one equation looks like this:
7 = .05x
Solve for x by dividing both sides by .05 to see that
x = 140
6x - 8 = 14 =))))))))))))))))
Multiply and then do the the same for pencils and notebooks
