Answer:
no real numbers will make this equation true
Step-by-step explanation:
if you square both sides, you'll get sqrt(-49). this will get you an imaginary number (7i) which is not a real number.
Answer:
The missing is 7
7 x (6 + 5) - (7 x 6) + (7 x 5)

Answer:
hahaha
ok so 70=z
a line is 180 degrees
so 180-70 is 110
so set the 4x+12 = 110
solve for x
u figure that out i don' t feel like doing that rn
once you find x
input it into 3x
get an answer
then add z (z is 70, from the beginning) to the answer u just got
and then ur gonna take that answer and subtract it from 180 degrees(3 angles of a triaNile add to 180 degrees)
then u should get you answer
have a nice day and stay safe
hope this helps
Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°
x - y = 35
x = 6y
Plug 6y in for x in the first equation.
6y - y = 35
5y = 35
Divide both sides by 5
y = 7
x = 6y
x = 6(7) = 42
42 and 7
Letter C
Since we had the answers we could have just tried the answers but you will not always have multiple choice so this is the method for solving.
