Solve in(5x+7)=8 round to the nearest thousandth

Ivan

Answer:

$x=\frac{1}{5}$

$x=0.2$

Step-by-step explanation:

$(5x+7)=8$

$5x+7=8$

Subtract 7 from both sides.

$5x+7-7=8-7$

Simplify.

$5x=1$

Divide both sides by 5.

$\frac{5x}{5} =\frac{1}{5}$

Simplify.

$x=\frac{1}{5}$

Decimal form:

0.2

Value of this problem?

Rudik [331]

$\frac{4^3\times4^{-1}\times5^{-2}}{4^4\times5^{-3}\times5^0}=\frac{4^{3-1}\times5^{-2}}{4^4\times5^{-3+0}}\\=\frac{4^{2}\times5^{-2}}{4^4\times5^{-3}}=4^{2-4}\times5^{-2-(-3)}\\=4^{-2}\times5^{1}=\frac{5}{4^2}\\=\frac{5}{16}$

A girl is 18 years old and her brother is a third of her age. When the girl is 36 what would be the age of the brother?

ale4655 [162]

First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old

Now when she gains another 18 years (36-18=18) he will also gain those 18 years

When she is 36 he will have 6+18=24 years old

Answer is 24.
