Answer: a= b/ b+2
Step 1: factor out variable a.
a(b+2)= b
Step 2: divide both sides by b+2.
a(b+2)/ b+2 = b/b+2
To solve this questions, we can turn 2 into a fractions.
2 as a fraction is 2/1 (because 2 divide by 1 is still 2)
We can now use this to get our answer.
1/3 ÷ 2/1
= 1/3 × 1/2 (flip the fraction and then multiply)
= 1/6 (1 x 1 / 3 x 6)
Or 0.16666.. as a decimal
#4 is actually f(x) + 18. #5 is f(x) + 201, #5 is f(x) + 316.
