The answer is -17.6.
It is -17.6 because when there is a number next to a letter you multiply.And 2.8 times 4 equals 11.2. Then you subtract it by -6.4.
so it is -6.4 - 4x2.8

Express the given expanded numeral as a Hindu-Arabic numeral. (8x102) +(4x10)(2x1)

Marysya12 [62]

Answer:

The Hindu-Arabic numeral form of the given expanded numeral is 842.

Step-by-step explanation:

The given expanded numeral is

$(8\times 10^2)+(4\times 10)+(2\times 1)$

We need to express the given expanded numeral as a Hindu-Arabic numeral.

According to Hindu-Arabic numeral the given expanded numeral is written as

$(8\times 10^2)+(4\times 10)+(2\times 1)=(8\times 100)+(4\times 10)+(2\times 1)$

On simplification we get,

$(8\times 10^2)+(4\times 10)+(2\times 1)=(800)+(40)+(2)$

$(8\times 10^2)+(4\times 10)+(2\times 1)=842$

Therefore the Hindu-Arabic numeral form of the given expanded numeral is 842.
