Answer:

The root of the equation is x=2.  

Step-by-step explanation:

Given : Equation 3x+1=7

To find : Solve for x?

Solution :

Step 1 - Write the equation

3x+1=7

Step 2 - Subtract 1 both side,

3x+1-1=7-1

3x=6

Step 3 - Divide the equation by 3,

\frac{3x}{3}=\frac{6}{3}

x=2

Therefore, The root of the equation is x=2.

If Peter withdrew $47.27 from the bank and deposited $598, how would his bank account change? (Indicate how much his account wou
fredd [130]

Answer:

Since we do not know the balance we should start with, a general answer:

b_{new} = b_{old} + \sum_{i} d_{i} - \sum_{j} w_{j} \\

598 - 47,27 = 550,73, assuming b_old was 0$ for your example

Step-by-step explanation:

b stands for balance (old - before any deposits or withdrawals, new after all done)

d for deposits

w for withdrawals

What are the solutions to the quadratic equation below? X^2-8x+16
leva [86]

(₋4)²

how i got it -

1st i used the sum-product pattern

x² - 8x + 16

x² -4-4+16

then, found the common fact from the two pairs

x² - 4 - 4 + 16

(-4) - 4(-4)

rewrite in factored form

(x-4)-4(-4)

(-4) (-4)

combine to a square

(-4) (-4)

Explain the difference between properties of equality and properties of inequality when solving equations and inequalities
algol [13]

Answer: An equality is a statement of equal measure. It stands for an absolute statement, without any leeway. That is, there is only a set number of solutions they can take.

Here is an example: x + 17 = 20

In this case, x can only take one solution because it is an absolute statement. Obviously, these can change, but conceptually, they will contain a set of answers a variable can take.

An equality with degree of n will inevitably have n number of answers a variable can take.

However, there are more solutions x can take for an equality. This is because inequality signs are a broader set of equality signs.

Example: x + 17 > 20

In the previous example, there was only one solution that x can take, namely x = 3. However, if we have an inequality, we're merely finding all sets of values x can take that will keep this statement true. In this case, there are an infinite amount of solutions, provided x is greater than 3.

Properties of inequalities vs equalities

This segment is quite tricky to grasp, because we are so used to the equality. The hardest section is to determine when to change the inequality sign. Whenever we multiply or divide by a negative number, we must flip the sign.

1.<br> A patient is told to force fluids to 3 L/day. How many mls should she drink?
Damm [24]

The patient should drink 3000 milliliter per day

<em><u>Solution:</u></em>

Given that a patient is told to force fluids to 3 liter per day

To find: Amount the patient should drink in milliliter

Use the conversion factor,

1 liter = 1000 milliliter

Now we have to find the amount the patient she drink in milliliter

Amount patient drinks in liter = 3 liter per day

Therefore, convert 3 liter to milliliter

3 liter = 1000 x 3 milliliter = 3000 milliliter

Thus the patient should drink 3000 milliliter per day
