Answer:

t = -13

Step-by-step explanation:

5t + 12 = 4t - 1

In order to solve this equation, you first need to add 1, so that it cancels out -1 on the right side. Since there is a rule saying that whatever you do to one side, you need to do to the other, you have to also add 1 to 12, since you can't add 1 to 5t. So,

5t + 12 = 4t - 1

+1 +1

5t + 13 = 4t

Now, you need to combine like terms, which would be the t variables:

5t + 13 = 4t

-5t -5t

13 = -t

We cannot have the - sign in front of the t, so we have to divide each side by - in order to remove the - in front of the t

13 = -t

/- /-

Answer:

T=-13

Step-by-step explanation:

Simplifying

5t + 12 = 4t + -1

Reorder the terms:

12 + 5t = 4t + -1

Reorder the terms:

12 + 5t = -1 + 4t

Solving

12 + 5t = -1 + 4t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-4t' to each side of the equation.

12 + 5t + -4t = -1 + 4t + -4t

Combine like terms: 5t + -4t = 1t

12 + 1t = -1 + 4t + -4t

Combine like terms: 4t + -4t = 0

12 + 1t = -1 + 0

12 + 1t = -1

Add '-12' to each side of the equation.

12 + -12 + 1t = -1 + -12

Combine like terms: 12 + -12 = 0

0 + 1t = -1 + -12

1t = -1 + -12

Combine like terms: -1 + -12 = -13

1t = -13

Divide each side by '1'.

t = -13

Simplifying

t = -13

What is the simplified form of the following expression? 7(^3 square root 2x) - 3 (^3 square root 16x) -3 (^3 square root 8x)

Pachacha [2.7K]

Answer:

The third option listed: $\sqrt[3]{2x} -6\sqrt[3]{x}\\$

Step-by-step explanation:

We start by writing all the numerical factors inside the qubic roots in factor form (and if possible with exponent 3 so as to easily identify what can be extracted from the root):

$7\sqrt[3]{2x} -3\sqrt[3]{16x} -3\sqrt[3]{8x} =\\=7\sqrt[3]{2x} -3\sqrt[3]{2^32x} -3\sqrt[3]{2^3x} =\\=7\sqrt[3]{2x} -3*2\sqrt[3]{2x} -3*2\sqrt[3]{x}=\\=7\sqrt[3]{2x} -6\sqrt[3]{2x} -6\sqrt[3]{x}$

And now we combine all like terms (notice that the only two terms we can combine are the first two, which contain the exact same radical form:

$7\sqrt[3]{2x} -6\sqrt[3]{2x} -6\sqrt[3]{x}=\\=\sqrt[3]{2x} -6\sqrt[3]{x}$

Therefore this is the simplified radical expression: $\sqrt[3]{2x} -6\sqrt[3]{x}\\$

State 5.126 to two decimal places

Kryger [21]

Answer:

5.13

Step-by-step explanation:

Look at the number at the end, and if it's 5 or more, round up. the 6 is greater than or equal to 5, so you round up, dropping the six and making the 2 into a 3, giving you 5.13.
