Let's first convert that amount of money into cents, which makes 336 cents. Then, let's denote the amount of money one of the boys has with x. The other boy has got 3x-12 amount of money. We can construct an equation.
. Solving it we find that x=87 cents or $ 0.87 and the other boy holds $2.49 amount of money.
Answer:
4 is always correct
Step-by-step explanation:
For x = -3, <span>(-0.7x) equals (-0.7[-3]), or 2.1.
8 8 8
Then f(-3) = ------------------- = ---------------- = ------------ = 0.31 (approx)
1 + 3*e^2.1 1 + 24.499 25.5</span>
Answer is D. Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for th remaining varables
