Hello, how was your day, help? ^ ^ solve for x

Natali5045456 [20]

Hi there!

»»————-　★　————-««

I believe your answer is:

$\boxed{x=100}$

»»————-　★　————-««

Here’s why:

Recall the Triangle Angle Sum Theorem: The three angles of all triangles add up to a sum of 180°.
We will set up an equation based on this and then solve.

⸻⸻⸻⸻

$\boxed{\text{Solve for 'x':}}\\\\58 + 22 + x = 180\\-----------\\\rightarrow 80 + x = 180\\\\\rightarrow 80 - 80 + x = 180 - 80\\\\\rightarrow \boxed{x=100}$

Hope this helps you. I apologize if it’s incorrect.

Suppose you pay $29.25 for a pair of shoes that has been discounted 35%. What is the original price of the shoes? Show how you i

Temka [501]

The answer is $30.

We know discounted price of the shoes - $24.
We need to find out the original price of the shoes - x.

The discounted price is 80% of the original price (it is said that shoes have been discounted 20%, so 100-20= 80%).

Let's set up a proportion. If $24 is 80%, how much is 100% (the original price):
$24 : 80% = x : 100 %

After crossing the products:
x = $24 * 100% / 80% = $30

Let's just check the result. After the discount of 20%, shoes will cost:
$30 - 20% = $30 - $30*(20/100) = $30 - $6 = $24.

The original price of the shoes is $30.

if the cost of a dress is multiplied by 5/8 the price then becomes $30.00 what was the original price

Alik [6]

Let's label the original price of the dress as x. We know that
$x \times \frac{5}{8} = 30$
so that means that we can find x by dividing both sides by 5/8:
$x = 30 \div \frac{5}{8}$
A simple rule for dividing fractions is 'Keep Change Flip'. You keep the first number/fraction the same, you change the ÷ to a × and you flip the second fraction. Through this rule, we can now solve the equation much more easily:
$x = 30 \times \frac{8}{5} \\ x = \frac{240}{5} \\ x = 48$
Therefore, the original price of the dress was $48
