Answer:

x=3

Step-by-step explanation:

You have to do the opposite of the operation to get the like terms on the same side of the equation sign. You have to add 22 to 29 (you add because its originally subtracted, or negative) and you add 7x to 10x. Then divide 51 by 17x giving you 3.

Find the value of x so that the polygons have the same perimeter.

Novosadov [1.4K]

Answer: x=4

Step-by-step explanation:

The perimeter´s formula for this kind of polygons is

The triangle perimeter would be:

(x+2)+(x+3)+(x+3)

And the rectangle:

(x+2)+(x+2)+x+x

For them to have the same value, we should equal them:

(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x

Working with this:

3x+8=4x+4

x=4

Alberto’s monthly income is $3,200. Part of Alberto’s monthly budget is shown in the table.

Sladkaya [172]

Using the percentage concept, it is found that 40% of Alberto’s income is used to pay for his rent and groceries.

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

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

In this problem:

Alberto’s monthly income is $3,200, hence b = 3200.

He spends 896 + 384 = $1280 in rent and groceries, hence a = 1280.

Then, the percentage is given by:

$P = \frac{1280}{3200} \times 100\% = 40\%$
