Describe the steps and order you use when solving an equation that involves the distributive property and combining like terms.

1 answer:

6 0

The rule to use is PEMDAS. (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction) When there's a number in front of one parenthesis, you distribute that number to the terms on the inside based on PEMDAS. What should also be notified is the exponent rules for multiplication and division. Then combine like terms. They have to have the same base of multiplying or dividing. Combining like terms need to have the same exponent, or whole numbers in groups.

Mr. Corbin measures the lengths of three branches. The first branch

anygoal [31]

Answer:

2nd branch > 1st branch > 3rd branch

$\dfrac{2}{2} > \dfrac{2}{3} > \dfrac{2}{8}$

Step-by-step explanation:

Length of First branch = $\frac{2}{3}$ foot

Length of second branch = $\frac{2}{2}$ foot

Length of third branch = $\frac{2}{8}$ foot

Let us convert the fractions in decimal forms:

$1.\ \dfrac{2}{3} = 0.67$

$2. \dfrac{2}{2} = 1$

$3.\ \dfrac{2}{8} = \dfrac{1}{4}=0.25$

It can be clearly seen that 1 is the largest value among the three values.

So, 2nd branch is the largest.

Now, let us have a look at the values of first and third branches:

0.67 and 0.25.

Clearly, 0.67 is greater than 0.25.

So, the correct order is:

2nd branch > 1st branch > 3rd branch

We can use other method to see it.

Here, all the 3 fractions have same numerator.

So, denominator can help us decide the which fraction has a large value.

If numerator is same, the larger denominator will have smaller fractions.

The denominators are 2, 3 and 8.

8 > 3 > 2

So, the answer is

2nd branch > 1st branch > 3rd branch

$\dfrac{2}{2} > \dfrac{2}{3} > \dfrac{2}{8}$

Answer:

The equation representing Number of miles in each section is $\frac{10}{4}$

Total Number of miles in each section is 2.5 miles.

Step-by-step explanation:

Given:

Total Miles bike race = 10 Miles

Number of sections = 4

Now we know that sections are divided in equal parts;

So Number of miles in each section can be calculated by dividing total miles of bike race with Number of section race.

The Number of miles in each section = $\frac{\textrm{Total distance in miles}}{\textrm{Number of sections}}$

Number of miles in each section = $\frac{10}{4}$

The equation representing Number of miles in each section is $\frac{10}{4}$

Solving the above equation we get;

Number of miles in each section = $\frac{10}{4}= 2.5 \ miles$

Hence Total Number of miles in each section is 2.5 miles.
