Answer:
x = -3/8
Step-by-step explanation:
4(3-2x)=15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 = 15-12
-8x =3
Divide each side by -8
-8x/-8 = 3/-8
x = -3/8
Answer:

Answer:
9.8 degree + 80.2 degree
As both need to add up to 90 degree to be complementary.
Step-by-step explanation:
Complementary angle means adds up to 90 degree.
Therefore- 90-80.2 = 9.8 degree
The answer is Subtraction
Answer:
x = 1 or x = -3/2
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + x - 3 = 0
The left hand side factors into a product with two terms:
(x - 1) (2 x + 3) = 0
Split into two equations:
x - 1 = 0 or 2 x + 3 = 0
Add 1 to both sides:
x = 1 or 2 x + 3 = 0
Subtract 3 from both sides:
x = 1 or 2 x = -3
Divide both sides by 2:
Answer: x = 1 or x = -3/2
