The sum of two numbers is 18 and their difference is 4 what are the two numbers?

Mathematics

Answer:

7 and 11

Step-by-step explanation:

Let the two numbers be x and y

x+y = 18

x-y = 4

Add the two equations together to eliminate y

x+y = 18

x-y = 4

----------------

2x +0y = 22

Divide each side by 2

2x/2 = 22/2

x = 11

Solve for y

x+y = 18

11+y =18

Subtract 11 from each side

11+y-11 =18-11

y = 7

The two numbers are 7 and 11

which equation represents this sentence? one-half the sum of a number and four is three less than the quotient of five and the n
Elena L [17]

a.) 1/2n 4=3−5/n b.) 1/2(n 4)=5/n−3 c.) 1/2(n 4)=3−5/n d.) 1/2n 4=5/n−3

Let's assume the number be n.

So, sum of number and four can be written as n+4.

Now one-half of n+4 will be \frac{1}{2} (n+4).

Quotient of five and the number can be written as \frac{5}{n}.

Now three less \frac{5}{n} can be written as \frac{5}{n} -3.

So, one-half the sum of a number and four is three less than the quotient of five and the number can be converted into equation as follows:

\frac{1}{2} (n+4)=\frac{5}{n}-3

So, b is the correct choice.

3. Find the area of the shaded region. Leave your answer in terms of pi. (1 point)
anygoal [31]

ANSWER

B.

(4 - \pi) {ft}^{2}

EXPLANATION

The area of the square is

{l}^{2}

The length of the square is

l = 2ft

The area of the square is

=  {2}^{2}  = 4 {ft}^{2}

Area of the circle is

= \pi \:  {r}^{2}

The radius of the circle is

r =  \frac{2}{2}  = 1ft

Area of circle is

= \pi \:  \times  {1}^{2}  = \pi {ft}^{2}

The area of the shaded region is

= (4 - \pi) {ft}^{2}
