Solving algebraic equations: 5n+1 What do I do to solve this?

emmainna [20.7K]

Explanation:

The given expression is not an equation. There is nothing that can be solved.

___

An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.

For example, we might have ...

5n +1 = 1

Your familiarity with math facts means you know that ...

0 +1 = 1

In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is n = 0, because 5×0 + 1 = 1 is a true statement.

___

An expression can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.

To evaluate 5n+1 for n=6 we put 6 in place of n:

5×6 +1

Doing the arithmetic, we get ...

= 30 +1 = 31

The value of 5n+1 for n=6 is 31.

The cost of renting a car is $46/week plus $0.25/mile traveled during that week. An equation to represent the cost would be y=46

julsineya [31]

The answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The equation to represent the cost would be y=46+0.25x

x is the number of miles.

a) What is your cost if you travel 57 miles?

Plug x = 57 in the above equation:

y = 46 + 0.25(57)

y = $60.25

b) If your cost was $65.00, how many miles were you charged for traveling?

Plug y = 65 in the equation:

65 = 46 + 0.25x

x = 76 miles

c) Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?

Plug y = 100 in the equation:

100 = 46 + 0.25x

x = 216 miles

Thus, the answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.

What is the value of x in the equation 4 . 10 X+52 3 +35x+1 5 ? :)

pashok25 [27]

Answer:

$x=-3$

Step-by-step explanation:

Given:

$4\frac{3}{10}-(2\frac{2}{5}x+5\frac{1}{2})=\frac{1}{2}(-3\frac{3}{5}x+1\frac{1}{5})$

Distribute to remove parentheses:

$4\frac{3}{10}-2\frac{2}{5}x-5\frac{1}{2}=-\frac{18}{10}x+\frac{6}{10}$

For simplification and clarity, reduce all mixed numbers to simplified common fractions:

$\frac{43}{10}-\frac{12}{5}x-\frac{11}{2}=-\frac{9}{5}x+\frac{3}{5}$

Combine like terms:

$-\frac{12}{5}x-\frac{6}{5}=-\frac{9}{5}x+\frac{3}{5}$

Add 6/5 to both sides, then add 9/5x to both sides:

$-\frac{3}{5}x=\frac{9}{5}$

Divide both sides by -3/5 to isolate x (recall dividing by a number is equal to multiplying by its reciprocal):

$x=\frac{9}{5}\cdot -\frac{5}{3}, \\x=\frac{-9}{3},\\x=\boxed{-3}$

Help pls (10 points)

Helen [10]

I believe it should be 8x

Since you are multiplying 2x with 4, only 2 is affected by 4

This results to 8x

Your answer is 8x

When you fill it in the blank the complete answer will be

8x + 8x

I hope this helps :)
