It is (B), because x+x+x-5+x-5=4x-10, so yes!
Oh, ok! Thank you both CPhill and Melody!
Is it possible to cross multiply?
If you know that h=2f, and we have to solve for f, we have to divide each side by 2. So, the answer is h/2
No problem!
(a) (4x-7)(4x-7)=16x^2-28x-28x+49
Total number of fruits: 4+5=9
4 apples, so the probability: 4/9
In mathematics, the logarithm is the inverse operation to exponentiation, just as division is the inverse of multiplication.
120%=90
1%=90/120
100%=90/120*100=75! Just like what CPhill got!
Is it 3? Bottom base: 4+9=13, right-angled triangle, so z=12, x=5. If we know one side is 5, and the other side is 4, y=3..
