This is all percentages so...
4/9 = 44%
2/7 = 29%
1/10 = 10%
Total = 83%
So 17% of 630 is left over which = 107
Answer:

Step-by-step explanation:
Given:

Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;

Step 2: Now we will try to make the denominator common so we will get;

Step 3: Now from the number line when we subtract 
from
we get number of spaces left are - 7
Hence now it will become:

Hence the final Answer is 
Answer:
A
Step-by-step explanation:
7x² - 4x - 8 - [ -3x² - 3x - 3]
In subtraction, flip the sign of all terms in the minuend
7x² - 4x - 8
<u> 3x² + 3x + 3</u>
4x² - x - 5
