Step-by-step explanation:

Just did the test and got it correct.

consider first number is = x

formula,

(n / 2)(first number + last number) = sum,

7/2(x+x+6)= 945

2x+6= 945×2/7

2x+6 = 270

2x= 270-6

x=264/2= 132

Answer the smallest number is 132.

Answer:

x = 41

Step-by-step explanation:

Number of sides , n

[tex]n = 10[/tex]

[tex]Interior \ angle= \frac{(n-2) \times 180}{n}[/tex]

[tex](5x -61) = \frac{(10-2) \times 180}{10}\\\\(5x - 61) = \frac{8 \times 180}{10}\\\\5x -61 = 144\\5x = 144 + 61\\x = 41[/tex]

Interior angle = 5x - 61 = (5 x 41) - 61 = 144

Answer:

-1/2

Step-by-step explanation:

Pick two points on the line

(-2,3) and (2,1)

Using the slope formula

m = (y2-y1)/(x2-x1)

   = (1-3)/(2 - -2)

   = (1-3)/(2+2)

    = -2/4

Answer:

-x^2+4x+6

Step-by-step explanation:

f(x) = 4x+1

g(x) = x^2 - 5

(f-g) (x) = 4x+1 - ( x^2 - 5)

Distribute the minus sign

            = 4x+1 - x^2 +5

Answer:

x = price of balcony tickets = $7

y = price of orchestra tickets = $21

Step-by-step explanation:

Let

x = price of balcony tickets

y = price of orchestra tickets

y = 3x (1)

148y + 76x = 3,640 (2)

Substitute y = 3x into (2)

148y + 76x = 3,640 (2)

148(3x) + 76x = 3,640

444x + 76x = 3,640

520x = 3,640

x = 3,640/520

x = 7

Substitute x = 7 into (1)

y = 3x (1)

y = 3(7)

y = 21

x = price of balcony tickets = $7

y = price of orchestra tickets = $21

Step-by-step explanation:

2.16=216/100=54/25

check your statement.

[tex]\frac{54}{25 }[/tex] is the rational number for the decimal 2.16

A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero.

According to the given question.

We have a number 2.16

To convert the above in rational number, we convert the given number  in [tex]\frac{x}{y}[/tex] form, where x and y are positive integers.

We read 2.16 as " 2 and sixteen hundredths".

Therefore, 2.16 can be written as [tex]2\frac{16}{100}[/tex].

Now we will simplify [tex]2\frac{16}{100}[/tex].

⇒ [tex]2\frac{16}{100} =2\frac{4}{25}[/tex]

⇒ [tex]2\frac{16}{100} =\frac{54}{25}[/tex]

Hence,  [tex]\frac{54}{25 }[/tex] is the rational number for the decimal 2.16

Answer:

64ft

Step-by-step explanation:

The distance between the lions and the monkeys is; 64 ft

From the given diagram, we see two triangles;

Triangle one formed by Zebras, Monkeys, lions.

Triangle two formed by tigers, elephants, lions

Now, from the given triangles we can see that they are similar and using the given dimensions, we can use proportion to find distance between the lions and the monkeys as;

52/78 = x/96

where x is the unknown distance we are looking for

We cross multiply to get;

4992 = 78x

Divide both sides by 78 to get;

x = 64 ft
