Let it be that Bob has 4x hats and 3x scarves. By selling 25 hats, the new ratio became 7:9. Mathematically, this may be expressed as,
7 / 9 = (4x - 25) / 3x
The value of x from the equation above is 15. Therefore, at the beginning of the day Bob has 45 scarves.
The y value will decrease as well
Answer:
z = 70
x = 6
Step-by-step explanation:
Z and 70 are vertical angles so they are equal
z = 70
12x+38 and 70 are supplementary angles so they form a straight line
This means they add to 180 degrees
12x+38 + 70 = 180
Combine like terms
12x+108 = 180
Subtract 108 from each side
12x+108-108= 180-108
12x = 72
Divide each side by 12
12x/12 = 72/12
x = 6
