I would do the rare ones because if they are rare more people might be interested and he would be cooler
Answer:
25%
Step-by-step explanation:
The ratio of rise to run is ...
rise/run = 6 ft/24 ft = 1/4
Expressed as a percentage, this is ...
1/4 × 100% = 25%
_____
<em>Comment on this grade</em>
Interstate highways are limited to a 7% grade. Most local jurisdictions limit the grade of a road to somewhere between 12% and 15%.
28. 6x+42-20=6x
42-20=0
42-20 gives you 22
22=0
Statement is false
30. -2x-4=-2x-3-1
-2x-4=-2x-4
Statement is true because both sides are identical
32. 2x+8-5=2x+3
8-5=3
3=3
Statement is true for any value of x
34. 3x+(x+4)=18
3x+x+4=18
4x+4=18
4x=18-4
4x=14 (next divide both sides by 4)
x= 7 over 2
7/2
(3x − 5) − (4x + 6)
Pretend that there is a 1 in front of the first bracket.
Pretend that there is a -1 in front of the second bracket.
Multiply the first bracket by 1
(1)(3x)=3x, (1)(-5)=-5
Multiply the second bracket by -1
(-1)(4)=-4, (-1)(6)=-6
3x-5-4x-6
3x-4x-5-6 ( combine like terms)
-x-11
Answer: -x-11 or -11-x
