A, the answer is A, something to do with opposite angles being the same, so A because 127 + 127 = 254
Answer:
n = s/180 +2
Step-by-step explanation:
180(n-2)=s
Distribute
180n - 360 =s
Add 360 to each side
180n -360+360 = s+360
180n = s+360
Divide each side by 180
180n/180 = s/180 + 360/180
n = s/180 +2
Answer:
mary has 135 coins.
Step-by-step explanation:
let the coins that john has be x
and coin mary than = 3x
according to the question equation is
x + 3x = 180
4x = 180
x = 180 / 4
x = 45
coins mary has = 3x
=3*45
=135
If you would like to know the values of a, b, and c in the quadratic equation -2x^2 + 4x - 3 = 0, you can find this using the following steps:
ax^2 + bx<span> + c = 0
</span>
-2x^2 + 4x - 3 = 0
a = -2
b = 4
c = -3
The correct result would be <span>d. a = –2, b = 4, c = – 3</span>.
The fractions from least to greatest (smaller to bigger) are 7/12 < 2/3 < 3/4
