Answer:

the answer is 35

Step-by-step explanation:

The whole angle equal 60, you get that from subtracting 120 from 180, then to find X you have to add 80 to 60 then divide the sum by 4.

Answer:

60+60 +4x-80 = 180

40 +4x = 180

4x = 140

x = 140/4

x = 35

angle = 60

hope it helps

Twice the sum of a number and 77 is equal to three times the difference of the number and 6.  Find the number
tino4ka555 [31]

x + 77 = 3(x - 6)

x + 77 = 3x - 18

x + 77 + 18 = 3x - 18 + 18

x + 95 = 3x

x + 95 - x = 3x - x

95 = 2x

x = 95/2

x = 47.5

Write an algebraic rule to describe the translation C(5, –4) C’(–2, 1)
sdas [7]
We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)

So, plugging in the values and solving for a and b,
5 + a = -2
a = -8

-4 + b = 1
b = 5

Therefore, the translation is
(x,y) (x - 8, y +5)

Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q.
Gelneren [198K]
<span>divide both sides of the equation by 2 to get: 

(x + 1/4)^2 = -7/16 ***** this is your solution. 

continue further to solve for x if you care to, but the problem did not require you to do this. 

take the square root of both sides of the equation to get: 

x + 1/4 = plus or minus sqrt(-7/16) 

subtract 1/4 from both sides of the equation to get x = -1/4 plus or minus sqrt(-7/16). 

since sqrt(-7/16) is the same as sqrt(7/16) * i, your solution becomes: 

x = -1/4 plus or minus sqrt(7/16) * i. 

your problem was to convert it to the form of (x + p)2 = q. 

the solution to that is: 

</span><span>(x + 1/4)^2 = -7/16 </span><span>subtract 1 from both sides of the equation to get: 

2x^2 + x = -1 

factor out a 2 on the left side of the equation to get: 

2 * (x^2 + x/2) = -1 

complete the squares on x^2 + x/2 to get: 

2 * ((x+1/4)^2 - (1/16)) = -1 

simplify by distibuting the multiplication to get: 

2 * (x+1/4)^2 - 2*(1/16) = -1 

simplify further to get: 

2 * (x+1/4)^2 - 1/8 = -1 

add 1/8 to both sides of the equation to get: 

2 * (x + 1/4)^2 = -7/8 .
