Divide. 0.0075 ÷ (1.5 x 10−6) write your answer in scientific notation.

Alborosie

0.0075 ÷ (1.5 x 10^-6) = (7.5 x 10^-3) ÷ (1.5 x 10^-6) = (7.5 ÷ 1.5) x (10^(-3 - (-6))) = 5 x 10^(-3 + 6) = 5 x 10^3

Answer:

$The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=8\ years$

Step-by-step explanation:

$Let\ the\ brother's\ present\ age\ be\ x\\Hence\ we\ are\ given,\\His\ sister's\ present\ age=(2x)\\Now,\\The\ brother's\ age\ before\ two\ years=(x-2)\\The\ sister's\ age\ before\ two\ years=3(x-2)\\Also,\\His\ sisters\ age\ before\ two\ years=2x-2\\Hence,\\3(x-2)=2x-2\\3x-6=2x-2\\3x-2x=6-2\\x=4\\Hence,\\The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=2x=2*4=8\ years$
