To solve for C, you have to get both of the numbers with a C on the same side.  So, subtract the 5c from the right side onto the left side.

8c = 5c + 21\\8c - 5c = 5c - 5c + 21\\3c = 21

Then, divide by 3 on each side.

3c = 21\\3c /3 = 21/3\\c = 7

So, c = 7.

That would be a simple linear equation in the variable 'c'. ... To find its solution, first subtract 5c from each side, then divide each side by 3 .

What is 4/5 as a decimal
Kryger [21]
.8

All percents are out of 100, so to figure out the answer you must make the denominator, or bottom number in your fraction, 100.

To get to 100, you would multiply 5x20, because that equals 100. Because you multiplied the denominator, which is 5, you must multiply the top number by 20 as well.

4x20 = 80

So therefore, the answer is 80/100, so .8

It is estimated that there are 22 deaths for every 10 million people who use airplanes. A company that sells flight insurance pr
Alex Ar [27]

Answer:

The insurance company can make $0.78 for each policy that it sells

Step-by-step explanation:

The loss incurred to the insurance company for each death claim is:

L = \$1-\$100,000=-\$99,999

This event has a 22 in 10 million probability of happening.

The gain for the company for each policy not claimed is:

G= \$1

This event has a 9,999,978 in 10 million probability of happening.

The expected value is:

EV =\$1*\frac{9,999,978}{10,000,000} -\$99,999*\frac{22}{10,000,000} \\EV=\$0.78

Therefore, over the long run, the insurance company can make $0.78 for each policy that it sells.

Type the correct answer in the box. Use numerals Instead of words. Consider the function shown on the graph. у 8 8 02 4 2 2 X -1
miskamm [114]

Answer:

Domain → [-5, ∞)

Range → [-2, ∞)

Step-by-step explanation:

Domain:

Domain of a function on from its graph is represented by the set of x-values (Input values).

Range:

Range of a function is a set of y-values (output values).

From the graph attached,

Graph starts from x = -5 and tends towards the infinity, so the domain will be,

Domain → [-5, ∞)

Similarly, y-values vary from y = -2 to y = ∞

Therefore, Range → [-2, ∞)
