x^a * x^b = x^ (a+b)


4^2 * 4^(-3)

4^(2-3)

4^(-1)

Answer: Statement 2 (P(odd number) = 1/2) is true

Bianca and Meredith are sisters. Meredith's height is 23 of Bianca's height plus 32 inches. Meredith is 60 inches tall. M Write
Anna [14]

Answer:

The height of Bianca  =  42 inches

Step-by-step explanation:

The given height of Meredith = 60 inches

Let us assume the height of Bianca = x inches

Now, given Meredith's height  =  2/3 of Bianca's Height + 32 inches

\implies  60 = \frac{2}{3 }  \times x  + 32

or,\frac{2}{3 }  \times x  = 60 -32  = 28\\\implies x = 28 \times  \frac{3}{2 }  = 42

or, x = 42

Hence the given height of Bianca  = x = 42 inches
