Answer:

27/8

Step-by-step explanation:

first you would convert -.5 to -1/2 and add everything up by getting the same denominator

Answer:

3.375

Step-by-step explanation:First convert the 2 1/4 and the 1 5/8

then you just add it with the 0.5 or just use a calculator  

2 1/4 = 9/4

1 5/8= 13/8

okay now do this ---> 0.5 + 9/4 +13/8 =3.375

Answer:

? = 5 cm

Step-by-step explanation:

∠ E and ∠ D are congruent, thus the triangle is isosceles and the 2 sides will be congruent, that is

? = 5 cm

Answer:

55

Step-by-step explanation:

2x+5 x-5 combine these to get 3x

then you would divide 180 by 3

so u would get 60 = x

60-5 =55

I thank it's 55 It wont let me post it because its too short

Answer:8.06

Step-by-step explanation:

4 x 4= 16 7 x 7 = 49

49+16=65

square root of 65 =8.06

Answer:

[tex] \sqrt{65} [/tex]

Step-by-step explanation:

To find the hypotenuese of a right angle you use the pythagreon theroem.

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.

[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]

The radical form answer is above, otherwise it would be a decimal.

Answer:

n=3

Step-by-step explanation:

3.4(107)=2(104)(1.7(10n))

n=3

Given:

A line passes through two points are (2,11) and (-8,-19).

To find:

The equation of the line.

Solution:

The line passes through two points are (2,11) and (-8,-19). So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-11=\dfrac{-19-11}{-8-2}(x-2)[/tex]

[tex]y-11=\dfrac{-30}{-10}(x-2)[/tex]

[tex]y-11=3(x-2)[/tex]

Using distributive property, we get

[tex]y-11=3(x)+3(-2)[/tex]

[tex]y-11=3x-6[/tex]

Adding 11 on both sides, we get

[tex]y=3x-6+11[/tex]

[tex]y=3x+5[/tex]

Therefore, the equation of line is [tex]y=3x+5[/tex]. So, the missing values are 3 and 5 respectively.

Answer: 3x+5

Step-by-step explanation:

Answer:

y= -2/5 x -4

Step-by-step explanation:

So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:

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

If you were using the points, (-10,0) and (0, -4) the equation would be:

m=(-4-0) / (0+10)

So, m= -2/5

The equation of the line would end up being:

y= -2/5 x -4
