Answer:
B
Step-by-step explanation:
6n - 2(4n + 7) + 4= -2 firstly you open the bracket
6n - 8n - 14 + 2 = -2 then you collect the like terms
6n - 8n= -2 + 14 - 4 then add and subtract and divide by the coefficient
-2n= 12 - 4
-2n = 8
= n = 8 ÷ -2
n = -4
Answer:
MZA = 140
Step-by-step explanation:
5x+25°+ x + 17°=180°(Supplimentary Angles)
6x + 42° =180°
6x =180 - 42
6x=138
(divide by 6 both sides)
X= 23
substitution X into the given angle
5x +25
5(23)+25
115+25
140
Answer:
x = 1/7
Step-by-step explanation:
2x + 3 = x + 15x + 6 − 5
<em>Combine like terms and solve:</em>
2x + 3 = 16x + 1
-14x + 3 = 1
-14x = -2
x = 1/7
hope this helps!! p.s. i really need brainliest :)
Answer:
0.11
Step-by-step explanation:
You would convert the percentage to a fraction. Since the % symbol means 'out of 100', you would put 11 over 100: 11/100.
Then you would convert the fraction to a decimal: 0.11.
An easier way could also be to take the percentage and move it two decimal places to the right.
Ex: 43% moved two decimal places to the right would be 0.43.
I hope this helps!
