- 485 - 319 = 166 more people
4.
- 14.5x + 80 > 500
- 14.5x > 420
- x > 420/14.5
- x > 29
5.
- 1.25x + 3 ≤ 28
- 1.25x ≤ 25
- x ≤ 25/1.25
- x ≤ 20 miles
6. <em>This seems a typo... 460 is likely $60</em>
- 60x + 145 ≤ 625
- 60x ≤ 625 - 145
- 60x ≤ 480
- x ≤ 480/60
- x ≤ 8 days

Answer:
648 is the answer
Step-by-step explanation:
9÷1=x÷72
x=9×72( cross multply)
x=648
Answer:
3/2
Step-by-step explanation:
Given y = 2x + 5, let's rewrite the equation in terms of x;
y = 2x + 5 => Bring 5 to the other side
2x = y - 5 => Divide either side by 2
x = (y - 5)/2
If we want to take the inverse, simply swap the variable's positions...
We have y = (x - 5)/2
Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1
f^-1(8) = (8 - 5)/2 = 3/2
Solution: 3/2
1) Between the pentagons, you take the small number over big number, so 6:14. But we can simplify that more all the way down to <em>3:7</em>

2) Between the squares, we can do the same thing.... <em>3:5</em>
<em></em>
3) Between the parallelograms, it would be <em>2:5</em>
<em></em>
4) Between the hexagons, it would be 4:12, but when we simplify, it becomes <em>1:3</em>
