Answer:

x = 5 ± √35

Step-by-step explanation:

Rewrite the left side as a square, then take the square root. Finally, add 5.

Answer:

C = (5/9)(F -32)
50°F ⇒ 10°C

Step-by-step explanation:

Starting with the formula for degrees Fahrenheit, we can solve for degrees Celsius.

F = 32 +9/5C

F -32 = (9/5)C . . . . . subtract 32

(5/9)(F -32) = C . . . . multiply by the inverse of the coefficient of C

The formula for Celsius temperature from Fahrenheit temperature is ...

C = (5/9)(F -32)

For F = 50, the corresponding Celsius temperature is ...

C = (5/9)(50 -32) = (5/9)(18) = 10 . . . degrees Celsius

The statements with their relation to 0 are:

Oliver owes his sister $27. $\to$ -27
A building is 38 feet tall. $\to$ 27
Erica jumped 2.7 feet above ground. $\to$ 2.7
The scuba diver was 38 feet below sea level. $\to$ -38
The basement is 8.3 feet below ground. $\to$ -8.3

Statements that represent positions above the sea level are illustrated using the positive sign, while positions below the sea level are represented using the negative sign.

The above highlights imply that the following statements would be represented with positive sign:

A building is 38 feet tall.
Erica jumped 2.7 feet above ground.

This is so, because height and positions above the ground are above the sea level

Also, the following statements would be represented with negative sign:

Oliver owes his sister $27. $\to$ -27
The scuba diver was 38 feet below sea level. $\to$ -38
The basement is 8.3 feet below ground. $\to$ -8.3

This is so, because debt and positions below the ground are below the sea level

The legs of a right triangle measure 7 and x. The<br> hypotenuse measures 25. Determine the value x

777dan777 [17]

According to Pythagoras :

The square of hypotenuse is the sum if the square if the two other side

so : 7^2 + X^2 = 25^2

49 + X^2 = 625

X^2 = 625-49

X^2 = 576

this equation as two roots . As a triangle cannot have a negative side value, I will only take positive value

so X = V576 =24
