Answer:

10=2n+(1/2n) n=4

Step-by-step explanation:

When reading the equation. Find the answer first, so when you write it out, you know what it is being compared to. Read it aloud to determine the solution clearly. Sum means add, and half means divide by 2, or 1/2.

10=2(4)+(1/2(4))

Answer:

C= 5.4

Step-by-step explanation:

Rise: 5

Run: 2

a²+b²=c²

c=√a²+b²

c=√rise²+run²

c=√5²+2²

c=√25+4

c=√29

c=5.385164807

c=5.4

Answer:

92

Step-by-step explanation:

If w=8 then you would multiply 9 by 8 which is 72. Then you would multiply 5 with 4 since x equals 4 which is 20. Then you would add 72+20 which gives you your answer which is 92

The value of expression 9w+ 5x when x=4 and w=8 is 92.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

Expression: 9w + 5x

Now, put x= 4 and w= 8 we get

9w + 5x

= 9(8) + 5(4)

= 72 + 20

= 92.

Hence, the expression gives 92.

Answer:

[tex]0.0454\ g/cm^3[/tex]

Step-by-step explanation:

We need to calculate 923 g ÷ 20312 cm³. 923 g will be in numerator and 20312 cm³ is in denominator. So,

[tex]D=\dfrac{923\ g}{20312 \ cm^3}\\\\D=0.0454\ g/cm^3[/tex]

So, the answer is [tex]0.0454\ g/cm^3[/tex] is the calculated answer.

Answer:

v =  4

Step-by-step explanation:

Given

- 5v + 4 = 2v - 6v, that is

- 5v + 4 = - 4v ( add 4v to both sides )

- v + 4 = 0 ( subtract 4 from both sides )

- v = - 4 ( multiply both sides by - 1 )

v = 4

Answer:

x = 30

Step-by-step explanation:

[tex]\frac{3}{5}[/tex](30) + [tex]\frac{1}{3}[/tex](30) = 28

[tex]\frac{3}{5}[/tex](30) = 18

[tex]\frac{1}{3}[/tex](30) = 10

18 + 10 = 28

[tex] \frac{3}{8} x + \frac{1}{3} x = 28[/tex]

[tex] \frac{9}{24} x + \frac{8}{24}x = 28[/tex]

[tex] \frac{17}{24} x = 28[/tex]

[tex]x = 28 \div \frac{17}{24} [/tex]

[tex]x = 28 \times \frac{24}{17} [/tex]

[tex]x = \frac{672}{17} [/tex]

Answer : 672/17

The picture is the proof

Answer:

see explanation

Step-by-step explanation:

∠ 1 = 42° ( alternate to ∠ FCD )

∠ CDF = 180° - 157° = 23° ( adjacent angles are supplementary )

∠ 2 = 23° ( alternate to ∠ CDF )

∠ 3 = 180° - (42 + 23)° = 180° - 65° = 115° ( sum of angles in triangle )

Thus

∠ 1 = 42°, ∠ 2 = 23°, ∠ 3 = 115°
