1 over 10x10x10 is basically, 10 to the power of 3. 10x10 is 100, and 100x10 is 1000. An easy way to do this. Since we have 3 tens, we start with 10, then add a 0, then add another 0. Gives you 1000.
9 is 12% of 75 check it 9* 100 = 900 / 75 = 12
Step-by-step explanation:
x = a + 7
y = b-a
To prove
x + y = b + 7.
- x+y= (a+7) + (b-a)
=a+7+b-a
=a-a+7+b
=0 + 7+b
= b+7
Proved ✅
