Each pie/circle has 10 sections. there is 3 whole sections so you would do 10x3 is equal to 30.

then, there’s a fourth pie that has one unshaded section. so, that would be only 9. add the 30 and 9 and you would get 39.

so, for the one fraction, you would get 39/10.

for the mixed number, you get 3 9/10 because 10 goes into 39 3 times and then you have 9 left over.

Enter number as an integer or decimal.
Strike441 [17]

Answer:

x

Step-by-step explanation:

30-4x>6x-10

Adding 10 to both sides.

10+30-4x>6x-10+10

40-4x>6x

Adding 4x to both sides.

4x+40-4x>6x+4x

40>10x

Dividing both sides by 10.

\frac{40}{10}>\frac{10x}{10}

4>x

∴ x
