Answer:
See below
Step-by-step explanation:
17. 17x + 3 x=4 18. -2x + 1 / 3 x= -5
17(4) + 3 - [(2)(-5) + 1] / 3
68 + 3 - [-10 + 1] /3
71 9/3 or 3
19. 2x - 33 x=9 20. - 9x - 2 x=7
(2)(9) - 33 -(9)(7) - 2
18 - 33 -63 - 2
- 15 -65
21. 7/3x - 9 x=3 22. - [12x/5] x= -1
(7/3)(3) - 9 - [(12)( -1)/5]
7 - 9 - [ -12/5 ]
-2 2.4
23. 11x - 11 x = -11 24. (2/9)x - (9/2) x= 9
- 121 - 11 (2/9)(9) - (9/2)
-132 2 - (9/2) ( 2 can be shown as 4/2)
(4/2) - (9/2)
- 5/2 or - 2.5
25. f(x) = 0.12x + 4.52 x = 250 26. f(x) = 0.18x + 3.12 x= 175
= (0.12)(250) + 4.52 = (0.18)(175) + 3.12
= 30 + 4.52 = 31.50 + 3.12
= 34.52 = 34.62
H,t,h,h they are both equal portability because you could get eithed
Hi! i think it’s d, just by process of elimination!! it cant be any of the others, and d estimates to be right.
Answer:
73.3
Step-by-step explanation:
50mi/h * 5280ft/mi * 1h/3600s = 220/3 = 73.3 ft/s
We have that
<span>[6x+5]=1+2*(3x+2)
[6x+5]=1+2*3x+2 --------> is not correct ------->1+ 2*(3x+2)=1+2*3x+2*2
then
</span>[6x+5]=1+6x+4---------------> [6x+5]=[6x+5]
<span>this equation is an identity, all real numbers are solutions.</span>
