The solution of 5x^2–3(x–2)+x for x = 3 is 45

<u>Solution:</u>

In this question we have been given an equation and asked to solve for a particular value of ‘x’.

The given equation is:

5x^{2}-3(x-2)+x

We have been asked to solve it for x=3.

So, we need to substitute the value of x as 3 in the equation and then simplify it as follows:

\begin{array}{l}{=5\left(3^{2}\right)-3(3-2)+3} \\\\ {=5(9)-3(1)+3} \\\\ {=45-3+3=45}\end{array}

Therefore, on solving the equation for x = 3 we get 45

To build 12 birdhouses, Felipe needs 5 1/4 meters of wood. He was asked to make 4 1/2 times the number of birdhouses he usually
Dimas [21]

Using proportions, it is found that Felipe needs 23.625 meters of wood to make that many birdhouses.

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

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

To make an amount, he needs 5 1/4 meters = 5.25 meters. How many meters he needs to make 4 1/2 = 4.5 times the amount?

5.25 x 4.5 = 23.625 meters.

Felipe needs 23.625 meters of wood to make that many birdhouses.

Katrina deposited $500 into a savings account that pays 4% simple interest. How much interest will she earn in 3 years if she ma
Dovator [93]

Answer: the amount of interest after 3 years is $60

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount of money deposited.

P represents the principal or amount of money deposited.

R represents interest rate on the deposit.

T represents the duration of the deposit in years.

From the information given,

P = $500

R = 4%

T = 3 years

Therefore,

I = (500 × 4 × 3)/100

I = $60
