1,2,5 are the answers I think. I hope this helped
When you solve a proportion, your first step should be to cross-multiply.

=

When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of
x is 15.
1) 84 hours
2) 2.4 meters
3) 4800 seconds
4) 100000grams
5)219.2 Fahrenheit degrees
The parabola has a minimum value of -3 due to the subtraction at the end of the equation.
The correct answer is D. 36 x 1/9
When there is a negative exponent on a whole number:
