$Factoring \: is \: the \: easiest \: way \\ 2 {x}^{2} + 12x = 0 \\ \Leftrightarrow 2x(x + 6) = 0 \\ \Leftrightarrow x = 0 \: \vee \: x = - 6$

Explanation:

Given:

$\log_a5 \approx 0.699$ and $\log_a2 \approx 0.301$

Note that from the properties of logarithms,

$\log_a20 = \log_a(5×4)$

$\:\:\:\:\:\:\:\:\:\:= \log_a(5×2^2)$

$\:\:\:\:\:\:\:\:\:\:=\log_a5 + \log_a(2)^2$

$\:\:\:\:\:\:\:\:\:\:=\log_a5 + 2\log_a2$

$\:\:\:\:\:\:\:\:\:\:\approx 0.699 + 2(0.301)$

$\:\:\:\:\:\:\:\:\:\:= 1.301$

A man has two more nickels than dimes. He has $1.15 in all. How many coins of each kind does he have?

zhannawk [14.2K]

Answer:

Man has 9 Nickels and 7 dimes.

Step-by-step explanation:

Let Number of dimes be x

and Number of Nickels be y

As Per given data he has two more nickels than dimes.

$y= 2+x\\$

As we know that

1 $\$$ = 100 cent

1 nickel is worth = 5 cents = $\frac{5}{100}$ = 0.05 $\$$

1 dime is worth = 10 cents = $\frac{10}{100}$ 0 .1 $\ $$

According to given data he has $\$\ 1.15$ total nickel and dimes

So the equation becomes,

$0.05y+0.1x=1.15$

but $y= 2+x$

$0.05(2+x)+0.1x=1.15\\0.1+0.05x+0.1x=1.15\\0.1+0.15x= 1.15\\0.15x= 1.15-0.1\\0.15x=1.05\\x=\frac{1.05}{0.15}= 7$

Substituting value of x in equation $y = 2+x$ we get

$y= 2+7 =9$

Man has 9 Nickels and 7 dimes.
