Cross multiply 10/a = 15/30 10/a(a)(30) = 15/30(30)(a) Simplify 1/a(a) = 1 15/30(30) = 15 10(30) = 15(a) Simplify. Combine terms 300 = 15a Isolate the a. Divide 15 from both sides 300/15 = 15a/15 a = 300/15 a = 20A) a = 20 is your answer hope this helps
Hello! To solve this we will cross multiply the first numerator by the second denominator and then divide by the other value you have besides a, which in our case is 15. 10(30)=300 300/15=20 Therefore, A=20 . I hope this helps!
