Answer: 2(n + 4) (n - 4)

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula,

a^2 - b^2 = ( a + b ) ( a + b )

On Monday, Torrance practiced the violin for 4/10 of an hour. On Tuesday, he practiced for 1 6/8 of an hour. How much time did h

Yuri [45]

Answer: $2\frac{3}{20}$

<u>Step-by-step explanation:</u>

First, convert mixed numbers into improper fractions and simplify all fractions

$\frac{4}{10}$ ÷ $\frac{2}{2}$ = $\frac{2}{5}$

$1\frac{6}{8}$ = $\frac{8(1) + 6}{8}$ = $\frac{14}{8}$ ÷ $\frac{2}{2}$ = $\frac{7}{4}$

Next, find their sum. Remember to find the LCD and convert the fractions so they have like denominators.

Monday + Tuesday = Total

$\frac{2}{5}$ + $\frac{7}{4}$ = Total <em>the LCD of 5 and 4 is 20</em>

$(\frac{4}{4})\frac{2}{5}$ + $(\frac{5}{5})\frac{7}{4}$ = Total

$\frac{8}{20}$ + $\frac{35}{20}$ = Total

$\frac{43}{20}$ = Total

Then, convert the improper fraction into a mixed number

$\frac{43}{20}$ = $2\frac{3}{20}$

forty-seven marbles are shared between some children. each child receives six marbles and there are five marbles left over. how

Nadya [2.5K]

The total number of children can be calculated using linear equation in one variable. The marbles are shared among 7children.

<u>Solution</u>

Total number of marbles = 47

The number of marbles received by each child = 6

Let the number of children be x

Then according to the question'

Total number of marbles received by all children + 5 = Total number of marbles

6x + 5 = 47

6x = 47- 5

6x = 42

x = 7

now, the number of children is 7.

<h3>What is linear equation in one variable?</h3>

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.
A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C.
Here, the variables x and y, the coefficients A and B, and the constant C are all present.
A linear equation's graph will always be a straight line.
One-variable linear equations are fairly simple to solve. To determine the value of the unknown variable, the variables are divided and placed on one side of the equation, and the constants are combined and placed on the other side.

The weight of an object on a particular scale is 145.2 lbs. The measured weight may vary from the actual weight by at most 0.3 l

joja [24]

1. Know what you're looking for:

The range is the difference between the lowest and highest values.

Your weight is 145.2 and can vary from the actual weight by maximum 0.3 lbs less or maximum 0.3 lbs more.

2. Calculate your lowest and highest values :

Lowest : 145.2 - 0.3 = 144.9 lbs

Highest : 145.2 + 0.3 = 145.5 lbs

3. Calculate the range of actual weights of the object :

145.5 - 144.9 = 0.6 lbs

--> The answer is: <u>The range of actual weights of the object is 0.6 lbs.</u>

There you go! I really hope this helped, if there's anything just let me know! :)

Examine the following equation and classify the type of solution.

Viktor [21]

Answer:

<h2>infinitely many solutions</h2>

Step-by-step explanation:

5x - 6 = 3x - 6 + 2x <em>combine like terms</em>

5x - 6 = (3x + 2x) - 6

5x - 6 = 5x - 6 <em>subtract 5x from both sides</em>

-6 = -6 TRUE

Therefore the equation has infinitely many solutions.
