The first step for solving this expression is to remove the first set of parenthesis.
-8.3x + 4 - (3.2x - 5)
Remember that when there is a "-" sign in front of the parenthesis,, we must change the sign of each term in the parenthesis. This will change the expression to the following:
-8.3x + 4 - 3.2x + 5
Collect the like terms with an x variable.
-11.5x + 4 + 5
Lastly,, add the numbers to get your final answer.
-11.5x + 9
Let me know if you have any further questions.

A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the field. How far does he walk

S_A_V [24]

Answer:

Patrick walk approximately 112 yards.

Step-by-step explanation:

Given:

A rectangular field is 50 yards wide and 100 yards long.

Patrick walks diagonally across the field.

Now, to find the distance he walk.

Length of the field = 100 yards.

Width of the field = 50 yards.

Now, to get the diagonal distance we put formula:

$Diagonal = \sqrt{length^2+width^2}$

$Diagonal = \sqrt{100^2+50^2}$

$Diagonal = \sqrt{10000+2500}$

$Diagonal = \sqrt{12500}$

$Diagonal = 111.80$

Therefore, Patrick walk approximately 112 yards.

Equivalent answers for 64 to the power of 2/3

madreJ [45]

Answer:

Step-by-step explanation:

Dealing with a fraction exponent on hand can be converted by using the fractional exponents rule where the fraction exponent is converted to something like this:

$64^\frac{2}{3} = \sqrt[3]{64^{2}}\\$

As you can see, the denominator of the fractional exponent is now the index of the radical. Here is a guide to know what goes where.

$64^\frac{x}{y} = \sqrt[y]{64^{x}}$

Both the original problem (64^2/3) and the converted formula can be put into a calculator.

Simplify (if you want to)

$\sqrt[3]{64^{2}}\\\sqrt[3]{4096}\\16$

64 to the power of 2/3 is 16.
