So, what you need to do is take away the parenthesis so you can combine like terms:
c+4-3c-2=0
Add 4 and -2: 4+-2=2
Add c and -3c: c+=3c=-2c

Now you have:
2-2c=0

Add the -2c to the other side so we can work on getting c alone:
2=2c

Divide by 2 so c will now be alone:
c=1
The answer is C

Hope this helps :)

Supposed charity received a donation of $23.9 million. If this represents 54% of the charity donated funds what is the total amo

Tanzania [10]

Total amount of funds is $44.26 million.

Step-by-step explanation:

Given,

Donation received = $23.9 million

As it represents 54% of charity.

Let,

Total amount = x

Therefore,

54% of x = 23.9 million

$\frac{54}{100}*x=23.9\\0.54x=23.9$

Dividing both sides by 0.54

$\frac{0.54x}{0.54}=\frac{23.9}{0.54}\\x=\$44.26\ millions$

Total amount of funds is $44.26 million.

A population of fish starts at 8,000 and decreases by 6% per year. What is the initial value, a? A.6% B.0.6 C.8,000

EleoNora [17]

Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t

You can see a = 8,000
As the fish population starts at 8,000

Students in a random sample of 57 students measured their handspan. The dot plots display the results for the males and females.

Nat2105 [25]

Answer:

There is a difference in mean hand span between male and female if you notice the difference between their averages. 2cm is quite significant

female mean = 19.6 cm and male mean = 21.6 cm

Step-by-step explanation:

a.) There is a significant difference.

take P( Z < ( 19.6 - 21.6) / 1) = P(Z < -2) = 2% probability of assuming that male and female means are the same. too low to think like that.

b.) Differ by 2cm. MAD= Mean Absolute Deviation , MAD within their own data set seem similar

C.) The variability in hand spans among male and female are very similar, since they both have the same MAD = 1.0

Find the circumference and area of a circle with the diameter AB,<br> A(-8,4) and B(4,-1)

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ A(\stackrel{x_1}{-8}~,~\stackrel{y_1}{4})\qquad B(\stackrel{x_2}{4}~,~\stackrel{y_2}{-1})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ AB=\sqrt{[4-(-8)]^2+[-1-4]^2}\implies AB=\sqrt{(4+8)^2+(-1-4)^2} \\\\\\ AB=\sqrt{144+25}\implies AB=\sqrt{169}\implies \stackrel{\textit{diameter}}{AB=13}~\hfill \boxed{\stackrel{\textit{radius}}{6.5}} \\\\[-0.35em] ~\dotfill$

$\bf \textit{circumference of a circle}\\\\ C=2\pi r\qquad \qquad C=2\pi (6.5)\implies C=13\pi \implies C\approx 40.84 \\\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \qquad A=\pi (6.5)^2\implies A=42.25\pi \implies A\approx 132.73$
