Answer:
0.8
Step-by-step explanation:
3(5x+2)+10=4
=15x+6+10=4
After this step you subtract 6 from each side and then subtract 10 from each side and then after that you divide 15x on each side which will give you 0.8.
Answer:

Step-by-step explanation:
Biquadratic Equation
It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results
Our equation is

If we call
, our equation becomes a second-degree equation

Dividing by -3

Factoring

It leads to these solutions

Taking back the change of variable, we have for the first solution

Now for the second solution, we get imaginary (complex) values

Summarizing, the four solutions for x are

Step-by-step explanation:
since the sumation of f(x) of a probability is 1
thw probability to win is o.5 and to lose is o.5 so expected value is xf(x
your expected value will b 0.5 multiply by 5 thats is 2.5 thats your expected gain
Answer: 2 tons.
Step-by-step explanation:
1 pound = 0.0005 tons.
4,000*0.0005=2
Jasmine's rhino weighs 2 tons
Answer:
b. Is because -3 because the the negative gets turned into a positive.
5. They are almost the same because subtraction change the negative to a positive and the -5+2 is the aftermath of what happend.
6. Its because the subtract a negative it cancels out and makes the number a positive.
