The product of some negative number and 4 less than twice that number is 286 find the number

Naya [18.7K]

Let's say that number is hmmm "a"

now.. twice "a" is 2*a or 2a
4 less than that is " 2a - 4"

now, the product of those two fellows is 286, well ok

a( 2a - 4) = 286

thus

$\bf a(2a-4)=286\implies 2a^2-4a^2=286\implies a^2-2a^2=143
\\\\\\
a^2-2a^2-143=0\implies (a-13)(a+11)=0
\\\\\\
\begin{cases}
a-13=0\implies &a=13\\
a+11=0\implies &\boxed{a=-11}
\end{cases}$

liraira [26]

Answer:

$\$173,319.50$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=8\ years\\ A=\$260,000\\ r=5.2\%=5.2/100=0.052\\n=1$

substitute in the formula above

$260,000=P(1+\frac{0.052}{1})^{1*8}$

solve for P

$260,000=P(1.052)^{8}$

$P=260,000/(1.052)^{8}=\$173,319.50$

Answer:

P(girl) = 40%, 2/5, or 2:5 (depends which one they're asking for)

Step-by-step explanation:

First, you need to find the number of girls in the class. Using the information given, in order to find the number of girls, you need to subtract the number of boys from the total number of students in the class (25-15). By doing this, you will see that there are 10 girls in the class. Now, in order to find the probability of choosing a girl, write the probability as a fraction (<em># of desired outcomes aka any outcome in which you choose a girl </em>- numerator / <em># of total outcomes aka total number of students in the class to choose from</em>). This will give you the fraction 10/25 , which simplifies to 2/5.

Hope this helps!!! Good luck!!!
