Answer:  The required value of x is -9.5.

Step-by-step explanation:  We are given to find the value of x from the following sentence after translating it into an equation :

"twice x, plus 5 is the same as -14".

According to the given information, the equation can be written and solved as follows :

2x+5=-14\\\\\Rightarrow 2x=-14-5\\\\\Rightarrow 2x=-19\\\\\Rightarrow x=-\dfrac{19}{2}\\\\\Rightarrow x=-9.5.

Thus, the required value of x is -9.5.

Translate that sentence into an equation. "Twice x" means 2 times x, so 2x. "Plus 5" means 5 is added to the 2x. "Is the same as" means that 2x+5 equals something, and -14 is the number it equals. So the equation would look like this: 2x+5=-14 Now this is a two-step equation. Subtract 5 on both sides. 2x=-19 Lastly, Divide by 2. x=-19/2 or -9.5

Donna wants to draw a right triangle. She wants the hypotenuse to be 1.5 inches long and one of the legs to be 1.2 inches long.
Nady [450]

Answer:

0.9 inches

Step-by-step explanation:

The sides of right triangles follow the Pythagorean Theorem:

a² + b² = c²

"a" and "b" are the two shorter sides and "c" is the hypotenuse, the longest side.

Let's plug in what we know.

a² + b² = c²

(1.2)² + b² = (1.5)²

Let's solve the exponents.

1.44 + b² = 2.25

Subtract 1.44 from both sides.

b² = 0.81

Take the square root of both sides.

√b² = √0.81

b = 0.9

The second side will be 0.9 inches.
