150, I believe
"if 40% of a number is 60" (40/100) * x = 60 (.4) x = 60 [reduce or just write it this way] x = 60(.4) [multiply both sides by .40]
Area of den =8x3 = 24ft²
living room = 7x6 = 42ft²
total = 24+42 = 66ft²
Ofcourse it is a linear function
why because every of x value of this function is 23 in result always
... so when we draw a chart it will be line on 23 coordinate ;)
Answer:
i believe it is x=4
Step-by-step explanation:
10x+7=12x-1
7=12x−1−10x
8=2x
divide
x=4
