P(X>3 cars) = 0.00638

2(t+1)=10. <br><br><br><br> need the answer for t I got the rest just can't get t

harkovskaia [24]

Answer: $t=4$

<u>Simplify both sides of the equation</u>

<u></u> $(2)(t)+(2)(1)=10(Distribute)\\2t+2=10$ <u></u>

<u></u>

<u>Subtract 2 from both sides</u>

<u></u> $2t+2-2=10-2\\2t=8$ <u></u>

<u></u>

<u>Divide both sides by 2</u>

<u></u> $\frac{2t}{2} =\frac{8}{2} \\t=4$ <u></u>
