Answer:
x = 14
Angle B = 121°
Angle C is 59°
Step-by-step explanation:
First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)
10x-19 = 7x+23 subtract 7x
3x-19 = 23 add 19
3x = 42 divide by 3
x = 14
Angle B is 10x-19, and if x=14, then its 10(14)-19
Angle B is 140-19
which is 121°
Angle B = 121°
Angle B and Angle C add up to 180°
121° + c = 180°
c = 180-121
Angle C is 59°
Answer:
7/12 or (Decimal: 0.583333)
Step-by-step explanation:
1/3 +1/4 = 7/12
A. 3a b. a^3 c. 4x d. 3pq e. 7^ef f. zxy^1
To simplify this, you would have to turn b^-2 into a positive exponent.
To do this, we have to flip b^-2, which would get rid of the negate from the exponent: -2
3a^4 b^-2 c^3 / b^-2
Then we get the answer:
3a^4 c^3
------------
b^-2
I have a picture to clarify!
