hello
8 the no right answer to 2(4x - 6) = 6x - 4
because : 2(4(8)-6) = 6(8)-4
2(26) = 48-4
52 =44
Z-score for 80% to pass = -0.842.

-60.624 = X - 426
X = 426 - 60.624
X = 365
Therefore the required passing score is 365.
230 times .30 is 69 so sub that from 230 you get 161
Answer:
7
Step-by-step explanation:
solving algebraically:
(x = the unknown number)
(our goal is to isolate x/get x by itself)
2x + 5 = 5x - 16 {equation written out}
-2x -2x
5 = 3x - 16
+ 16 + 16
21 = 3x
÷3 ÷3
7 = x
check:
(2)(7) + 5 = (5)(7) - 16
14 + 5 = 35 - 16
19 = 19
hope this helps!!
