The equation 2y+53=165 represents the situation “ Joel spent $165 on a pair of jeans and two shirts at the same price.”

tia_tia [17]

To find the answer, let's first figure out what the formula is saying. Since we know Joel spent a total of $165, the right side of the formula represents the total while the left side is made up of the costs of the clothing. Now, since we know that he purchased 2 shirts, the 2y in the formula would represent the total cost of two shirts. Therefore, simply y would represent the price of a shirt.

I hope this helps.<span />

Answer:

x = 3.75

Step-by-step explanation:

ABC is a right angled triangle.

Therefore, by Pythagoras theorem:

${(10 - x)}^{2} = {x}^{2} + {5}^{2} \\ 100 - 20x + {x}^{2} = {x}^{2} + 25 \\ 100 - 20x = 25 \\ - 20x = 25 - 100 \\ - 20x = - 75 \\ x = \frac{ - 75}{ - 20} \\ \: \: \huge \red { \boxed{x = 3.75}}$
