Equivalent ration of <br> b/40=9/10<br> b=____ ?
NARA [144]

Answer:

The correct answer is <em>b = 36</em>

Step-by-step explanation:

In order to find out what b is, you must find out what 9/10 is.

9/10 is 0.9. This will later be used to check our answer.

Now, solve by using cross-multiplication

b * 10 = 9 * 40.

Then use the commutative property to reorder the terms

10b = 9 * 40

Now Multiply 9 * 40 = 360

10b = 360

Now divide both sides of the equation by 10

<em>b = 36</em>

Dale currently has $599 in his savings account. Prior to getting paid, he had $230 in his savings account. How much was Dale’s p
nlexa [21]
Hi!

So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599. 

Take the parts I put in bold, and write the equation.
$230 + x = $599

Now we need to find x. 

Whatever we do to the equation, we do it to both sides. 
Our goal is to isolate x on one side. 

Subtract 230 from both sides. 
$230 - $230 + x = $599 - $230
x = $369

The answer is A. $230 + x = $599 x = $369

Hope this helps! :)
