HOW DO I SOLVE THIS PLEASE HELP

Answer:

x = 15

Step-by-step explanation:

We assume you want to find the value of x.

Know (or prove) that in this geometry, all of the right triangles are similar. That means the ratios of corresponding sides are proportional.

short side / hypotenuse = 9/x = x/25

x^2 = (9)(25) . . . . . . . . . . multiply by 25x ("cross multiply")

x = √((9)(25)) = (3)(5) . . . take the square root

x = 15

Which inequality correctly compares Two-fifths, Six-sevenths, Five-eighths, and 1?

Ronch [10]

Answer:

2/5 < 5/8 < 6/7 < 1

OR

1 > 6/7 > 5/8 > 2/5

Step-by-step explanation:

It is required to compare Two-fifths, Six-sevenths, Five-eighths, and 1

Two-fifths = 2/5

Six-sevenths = 6/7

Five-eighths = 5/8

So, the given numbers are: 2/5, 6/7, 5/8, and 1

We need to make the numbers in order from the least to the greatest or from the greatest to the least

The easy method is convert the rational numbers to decimal numbers

So,

2/5 = 0.4

6/7 ≈ 0.857

5/8 = 0.625

1 = 1

So, the numbers form the least to the greatest are:

0.4 , 0.625 , 0.857 , 1

So,

2/5 , 5/8 , 6/7 , 1

The inequality correctly compares the numbers are:

2/5 < 5/8 < 6/7 < 1

Or can be written from the greatest to the least as:

1 > 6/7 > 5/8 > 2/5

Ming and ivy each sell lemonade. Ming spends $15 on supplies and and all plans to charge $1.50 per cup. Ivy spends $20 on suppli

Marrrta [24]

Answer:

Step-by-step explanation:

1.5x - 15 dollars = x - 20 Add 15 to both sides.

1.5x - 15 + 15 = x - 20 + 15

1.5x = x - 5 They will never coincide.

1.5x-x = - 5

0.5x = - 5 Multiply by 2

x = - 10

I would check your question.
