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.

Which of the following expressions has a value of 26.48?
gulaghasi [49]

Answer:

26.48=\dfrac{662}{25}

Step-by-step explanation:

The given expression is 26.48. We need to write the equivalent expression for it. There are two numbers after decimal. It means that we can divide 2648 by 100 i.e.

26.48=\dfrac{2648}{100}

We know that, 2648 = 662 × 4 and 100 = 25 × 4

\dfrac{2648}{100}=\dfrac{662\times 4}{25\times 4}\\\\=\dfrac{662}{25}

Hence, 26.48=\dfrac{662}{25} is the equivalent expression.

3y + 12 = -3

Subtract 12 on both sides

3y = -15

Divide by 3 on both sides

y = -5
