First you need to make both denominators the same number.
The number we can use is 21.
6/7 : to make the denominator 21, you need to multiply the numerator and the denominator by 3.
6 × 3 = 18
7 × 3 = 21
The equivalent is 18/21
1/3 : to make the denominator 21, you need to multiply the numerator and the denominator by 7.
1 × 7 = 7
3 × 7 = 21
The equivalent is 7/21
18/21 + 7/21 = 25/21 = 1 4/21
Answer:
Step-by-step explanation:
(10 - x^2)/b = b/2
Cross multiply
2(10 - x^2) = b^2
20 - 2x^2 = b^2
2x^2 = 20 - b^2
Dividing through by 2
x^2 = (20 - b^2)/2
√x^2 = √(20 - b^2)/2
x = √(20 - b^2)/2
