(PLEASE DO ASAP, I"LL GIVE BRAINLIEST) Which of the following is not the way you write the ratio of a to b?

a. a:b

b. a/b

c. Ratio of a to b

d. Ratio of b to a

d is the answer

Step-by-step explanation:

B and D

Step-by-step explanation:

first of all, b has nothing so that's automatically out. And it's given that 'ratio of a to b' so it has to be A to B not B to A because that's like saying ; 'which one is 1:2? 1:2 or 2:1?' (obviously 1:2). Hope that makes sense!

it's both, now can you answer my most recent question?

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
