I need help how to do this. Please help
earnstyle [38]
The best method would be to cross-multiply. Multiply the figure on the top left with the bottom right. Then set it equal to the multiplication of the bottom left with the top right.
This would turn into:
-1(x-1)=2(x+3)   Then distribute the multiplication through the parentheses.
-x+1=2x+6     Next, get all the variables on one side, and the integers on another.
2x+x=1-6
3x= -5
x= -5/3

The side of a square is 5 cm more than the side of another square. If the sum of their areas is 625 cm², then the side of the bi
jekas [21]

Answer:

20 cm is the side of the bigger square.

Step-by-step explanation:

Let one square's side be x,

Then another squares side will be ( x + 5 )

  • <em>Formula for square's area: side²</em>

Total area:

  • x² + ( x + 5 )² = 625
  • x² + x² + 10x + 25 = 625
  • 2x² + 10 x + 25 - 625 = 0
  • 2x² + 10x - 600 = 0
  • 2(x² + 5x - 300) = 0
  • x² + 5x - 300 = 0
  • x² + 20x - 15x - 300 = 0
  • x(x + 20) -15(x + 20) =0
  • x = -20, 15
  • x = 15

So one square's side is 15 cm

Then the bigger square has:

  • x + 5
  • 15 + 5
  • 20 cm

Beach towels are currently selling 3 for 25 or 10 each what is the percent saved by buying 3
Virty [35]

Answer:

I am saving 16.67% when I buy 3 towels together.

Step-by-step explanation:

Beach towels are currently selling 3 for $25 or $10 each.

So, if I purchase 3 towels then I have to pay $25 in place of (3 × 10) = $30.

So, $(30 - 25) = 5 Dollars is saved by me on a price value of $30.

Therefore, the percentage of savings is calculated as \frac{5}{30} \times 100 = 16.67%.

Therefore, I am saving 16.67% when I buy 3 towels together. (Answer)
