Answer:
I got 17.
Step-by-step explanation:
Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)

The answer would be 7.5, since 6/9=2/3 and 5/7.5=2/3, then the sides are equal ratios.

Please check the attached number line graph.
The number line clearly indicates that the graph is heading towards negative infinity from -2.
Step-by-step explanation:
Given the inequality expression
x ≤ -2
The inequality symbol ' ≤ ' means 'less than or equal to'.
Thus,
x ≤ -2 means x is less than or equal to -2.
In other words,
![x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}](https://tex.z-dn.net/?f=x%5Cle%20%5C%3A-2%5Cquad%20%3A%5Cquad%20%5Cbegin%7Bbmatrix%7D%5Cmathrm%7BSolution%3A%7D%5C%3A%26%5C%3Ax%5Cle%20%5C%3A-2%5C%3A%5C%5C%20%5C%3A%5Cmathrm%7BInterval%5C%3ANotation%3A%7D%26%5C%3A%28-%5Cinfty%20%5C%3A%2C%5C%3A-2%5D%5Cend%7Bbmatrix%7D)
