Answer:
14 days
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
25n+100=450
Step 2: Subtract 100 from both sides.
25n+100−100=450−100
25n=350
Step 3: Divide both sides by 25.
25n/25 =350/25
n=14
Answer:

Step-by-step explanation:
-64 would be the whole number.
.875 would be 875/1000 as a fraction.
Put them together:

Simplify:

Answer:
Purple line: 4
Red dashed line: 2
Blue line: 1/2
Step-by-step explanation:
The purple line is the steepest line, therefore it has the biggest constant of proportionality or slope. Since 4 is the biggest number among the others, we attribute it to the purple line (the one with the point C on it).
Think of it this way:

here
so 
The greater a is, the greater y is. So for any value of x, y will be become bigger and bigger if we increase the value of a.
Take for example this one:

Take
therefore
Now take
and take
therefore
When we increased this constant of proportionality, as you can see from 2 to 4, the value of y increase from 4 to 8.
Hope this is helpful. Think of it really carefully, and I'm sure you'll grasp the concept.
