Which system of equation should you use to solve this problem
Alex17521 [72]

Last option is the correct answer.

Step-by-step explanation:

Given that

Let x stand for the solution a and y stand for the solution B

So,

According to statement that

30 gallons have to be made

x+y=30

Solution A contains 29 percent bromine => 0.29x

Solution B contains 53 percent  =>0.53y

And the mixture of 30 gallons contains 45% bromine

0.29x+0.53y=30*0.45\\0.29x+0.53y=13.5

Following equations will be used for solving the problem

x+y = 30\\0.29x+0.53y=13.5

Hence,

Last option is the correct answer.

What is the value of y if y = |– 5|?​<br><br> explain how you would get the answer step by step
Andrews [41]

Answer:

y=5

Step-by-step explanation:

The answer is 5 because that sign around the -5 is the absolute value sign. What the absolute value sign does is it measures the distance from 0 the number is. Since the number -5 is 5 units away from the number 0, then y=5.
