Answer:
The solution is the area x < 67/5
Step-by-step explanation:
Perform the indicated multiplication. We get:
9x - 27 < 4x + 40
Combining like terms results in:
5x < 67
Then the solution is the area x < 67/5
So because 9 and 10 are close to each other, and the fact that 10 is really easy to multiply by, you do 473 x 10 which is 4730, because you just add a 0 to the end.
This means that an estimate is 4730 or if you want to be less specific, <4730, because 9 is less than 10.
The actual product though is 4257.
That would be true because 2*4=8 and 2 goes into 8 4 times so that would be 1/4
Unlikely because 2 girls over 7 children is less then 50%
