Answer:

75.8°

Step-by-step explanation:

x + x + 28.4° = 180°{ being linear pair }

2x = 180° - 28.4°

2x = 151.6°

x = 75. 8°

Hope it will help :)

What is the sum of 3 consecutive odd integers is -39

trapecia [35]

Answer: The three consecutive odd integers are: -15, -13, and -11 .
_______________________________________________________
Explanation:
_____________________________________________
x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
in which "x" is one of the integers,
"(x + 2)" is the next consecutive odd integer;
"(x + 4)" is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
x + (x + 2) + (x + 4) = -39 ;
_________________________________________________________
1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________
3x + 6 = -39 ;
______________________________________________
Subtract "6" from EACH side of the equation:
______________________________________________
3x + 6 − 6 = -39 − 6 ;
____________________________________________________
to get: 3x = -45 ;
____________________________________________________
Divide EACH side of the equation by "3" ;
____________________________________________________
3x / 3 = -45 / 3 ;
_____________________________________________________
to get: x = -15 ;
______________________________________________________
x + 2 = -15 + 2 = -13 ;
_______________________________________________________
x + 4 = -15 + 4 = -11 .
___________________________________________________
Are: -15, -13, and -11 ; Consecutive odd integers? YES!
___________________________________________________
Does: -15 + (-13) + (-11) =? = -39 ??
_____________________________________________________
-15 − 13 − 11 = ? 39 ?? YES!
____________________________________________________
Answer: The three consecutive odd integers are: -15, -13, and -11.

Hi!! please answer he questions below using inverse operations! (if you show work i will give you brainiest!)

solniwko [45]

Answer:

13) 90-18 = 72

14) 108/9 = 12

15) 66+34 = 100

16) 7*8 = 56

Step-by-step explanation:

All you need to do is take the second term of each equation and move it to the other side. So for number 16 we just need to move the 8 from the left to the right. This is as simple as multiplying both sides by 8 to get:

8*(56/8) = 8(7)

56 = 8*7

And that would be the answer to number 16!
