Answer:

r = h + m

Step-by-step explanation:

h = r - m

Switch sides.

r - m = h

Add m to both sides.

r - m + m = h + m

Simplify the left side. -m + m = 0

r = h + m

Despejar la variable <br> 2x al cuadrado + 15= 113
Rudik [331]

Hola!

x = 7 , x = -7

Explicación:

Comienza restando 15 en cada lado:

2x^{2} + 15 -15=113-15

Usted obtiene:

2x^{2} =98

Ahora divide ambos lados por 2:

\frac{2x^{2} }{2} =\frac{98}{2}

Usted obtiene:

x^{2} =49

Como la ecuación está al cuadrado, tendrás que hacer:

x=\sqrt{f(a)} , x=-\sqrt{f(a)}

que te da: x=\sqrt{49} , x =-\sqrt{49}

Entonces:

\sqrt{49}=7 , -\sqrt{49}  = -7

What is 2,024,999,999 rounded to the nearest ten million?
bagirrra123 [75]
To round to the nearest ten million, check the millions digit after it:

2 , 0 2 4

The millions digit is 4, so you will round down to 0. All digits after this number will be converted to 0.

Rounded to the nearest ten million, the number becomes 2,020,000,000.
