Answer:
x = -3 and x = 1/2
Step-by-step explanation:
To find the solutions to
2x² + 5x - 3 = 0
we can use the quadratic formula, as follows:







a- 2/5 + 1/4=.65 mixture of red and blue paint
(2/5) / .65 X 1.625=1 gallon of red paint
(1/4) / .65 X 1.625=5/8 gallons of blue paint, because
1 + 5/8=1 5/8 gallons of purple paint.
b-1/10 + 2/5 + 1/4=.75 mixture of white, red and blue paint
***FINAL answer: 1 gallon red, 5/8 gallon blue.***
- 3.9 / 1.3 = - 3/1 = - 3
Calculation Steps:
Conversion:
3.9 = 39/10
Unary Minus:
- 3.9 = - 39/10
Conversion:
1.3 = 13/10
Divide:
- 39/10 : 1.3
= - 39/10 * 10/13
= - 39 * 10/ 10 * 13
= - 390/130
= - 3
Answer: - 3
