Answer:
5
Step-by-step explanation:
cross multiply
isolate x
12x=7.5(8)
12x=60
12x/12=60/12
5 is the answer
W = 2hx - 11x
w = x(2h-11)
w
---------- = x
2h - 11
Answer:
30%
Step-by-step explanation:
It would take your every year in rent money to divide it with your annual earnings to find the percent of 30.
Answer: -24
Step-by-step explanation:
Let the unknown number be x , therefore ; The difference between the number and 6 implies x - 6
Also , twice their difference implies 2 ( x - 6 )
The sum of the number and 4 implies : x + 4
three times their sum implies : 3 ( x + 4 )
Combining all together , we have
2 ( x - 6 ) = 3 ( x + 4 )
Expanding , we have
2x - 12 = 3x + 12
collecting the like terms , we have
2x - 3x = 12 + 12
-x = 24
multiply through by -, we have
x = -24
Check :
2 ( x - 6 ) will give
2 ( -24 - 6 )
= 2 (-30)
= -60
3 ( x+4) will give
3 ( -24 + 4 )
= 3 ( -20)
= -60
Therefore:
2( x- 6 ) = 3 ( x + 4 )
