Step-by-step explanation:

Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.

a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as

7.2×10^{-11}

The exponent of 10 is a negative number because you moved the decimal point to the right.

b) Similarly, you have to move the point 9 times to the right so the answer is

9.5×10^{-9}

What is 2\3y plus y minus 4 equals 31
steposvetlana [31]

Hi


2/3 y+y-4=31

Simplify both sides of the equation

2/3 y-4=31

Combine like terms

(2/3 y+y)+(-4)=31

5/3 y-4=31

Add 4 to both sides

5/3 y-4+4=31+4

5/3 y=35

Multiply both sides 3/5

(3/5)*(5/3 y)=(3/5)*35

y=21


I hope that's help !

María tiene el triple de la edad de su hermana Claudia. Dentro de 5 años, la edad de María será el doble de la de Claudia. Calcu
NemiM [27]

Respuesta:

Edad de Claudia = 5 años

Edad de María = 5 * 3 = 15 años

Explicación paso a paso:

Dejar :

Edad de Claudia = x

Edad de María = 3x

En 5 años :

3x + 5 = 2 (x + 5)

3x + 5 = 2x + 10

3x - 2x = 10-5

x = 5

Edad de Claudia = 5 años

Edad de María = 5 * 3 = 15 años
