What is the value of y in the equation 5x+2y=20, when x=0.3

Rasek [7]

5x+2y=20

Substitute 0.3 for x

5(0.3)+2y=20

Multiply 5 by 0.3

1.5+2y=20

Subtract 1.5 from both sides

2y=18.5

Divide 2 on both sides

Final Answer: y= 9.25

Solve the problem. Make sure your answer is in simplest form. 3/16 x 4/21 = ?

Irina18 [472]

Answer:

$\frac{1}{28}$

Step-by-step explanation:

The result is given by means of some algebraic handling:

$\frac{3}{16}\times \frac{4}{21}$

$\frac{12}{336}$ - Multiplication of rationals.

$\frac{6}{168}$ - Dividing each term by 2.

$\frac{3}{84}$ - Dividing each term by 2.

$\frac{1}{28}$ - Dividing each term by 3.

Solve the following quadratic equation by the square root method. (Y-9)^2=64

enot [183]

Hello!

To solve this, first perform the opposite operation for the last operation (on the left side) on both sides. The last operation of the left side is squaring. Therefore, square root both sides.

$(y - 9)^{2} = 64$

$y - 9 = ±\sqrt{64}$

$y - 9 = ±8$

Please note that you must include ±. This is because the square root of 64 can be either positive or negative, as a square of either a positive or negative number is positive.

Now, add 9 to both sides.

$y = 9±8$

There are 2 solutions from here. One comes from adding 8, and the other subtracting 8. Therefore, the two solutions are:

y = 9 + 8 = 17

y = 9 - 8 = 1

Therefore, your two solutions are 17 and 1.

Hope this helps!
