7 is not equal to the others
using the laws of exponents
/ 
= 1 / 
= 
=
Apart from 7 the other 3 all equal
The answer is -2 because 8(-2)-3=-19
8(-2)= -16-3=-19
Answer:
168 is the answer if i m not wrong.I took the LCM.
Let x = Horseback riding and y = Parasailing
Eq. 1
3x + 2y = 192
Eq. 2
2x + 3y = 213
By elimination:
<span> 2(3x +
2y = 192)</span>
+ -3(2x + 3y =
213)
<span> -5y = - 255</span>
y = $ 51
Substitute y :
3x + 2y = 192
3x + 2(51) = 192
<span>x = $ 30
</span>
<span>Hope this
answer will be a good help for you.</span>
