Let L represent the number of ribbons Lily has and D be the amount of ribbons Dora has.
Since Lily has 4 fewer ribbons than Dora, the amount of ribbons Lily has can be represented as this:
L = D - 4
Because Lily has 7 ribbons, you can plug in 7 for L:
7 = D - 4
When you solve for the amount of ribbons Dora has (D), which is done by adding 4 to both sides, you get D = 11.
Therefore, Dora has 11 ribbons.

Answer:
a) 4w + 16 = 50.
Step-by-step explanation:
The garden's length is obviously 8 feet longer than the width. If width were represented by w, the length would be w + 8.
We are calculating the perimeter, which is 2 times the length plus 2 times the width. That adds up to be 50.
2(w) + 2(w + 8) = 50
2w + 2w + 16 = 50
4w + 16 = 50
So, the answer is a) 4w + 16 = 50.
Hope this helps!
Exponential functions are related to logarithmic functions in that they are inverse functions. Exponential functions move quickly up towards a [y] infinity, bounded by a vertical asymptote (aka limit), whereas logarithmic functions start quick but then taper out towards an [x] infinity, bounded by a horizontal asymptote (aka limit).
If we use the natural logarithm (ln) as an example, the constant "e" is the base of ln, such that:
ln(x) = y, which is really stating that the base (assumed "e" even though not shown), that:
if we try to solve for y in this form it's nearly impossible, that's why we stick with ln(x) = y
but to find the inverse of the form:
switch the x and y, then solve for y:
So the exponential function is the inverse of the logarithmic one, f(x) = ln x
