Answer:
3
Step-by-step explanation:
75
/5
−[(9−7)(3)](2)
=15−[(9−7)(3)](2)
=15−[(2)(3)](2)
=15−(6)(2)
=15−12
=3
Answer:C.
Step-by-step explanation:just took on edge
<u>Answer:</u>

Solve brackets
6(0.66x-3)>8
Multiply 6 with values in the bracket
<em>So, 6x0.66x and 6x-3</em>
4x- 18> 8
Since 4x and 18 are unlike terms, we will take 18 onto the other side, thus:
4x>8+18
4x>26
<em>Now to find the value of x, divide 4 on B.S</em>
x> 
X> 6.5
OR in 'fraction form'
X>
Hope this helps :D
Set y to 0 and solve. 0 = 4( -1/2 ) + 2.
x = -1/2
