Tammy drove 715 miles in 11 hours. at the same rate, how long would it take her to drive 845 miles?

Alex787 [66]

Answer:

Step-by-step explanation:

So we have direct proportions here.

715=11

845=x

845*11/715

x=13

To check our work.

715/11=65

65*13=845.

Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/

So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.

Hope this helped, ask me if you have any questions.

Someone help ASAP solve -5x^2+7x=-9

Ray Of Light [21]

Answer:

$x=\frac{7 +/-\sqrt{229} }{10}$

Step-by-step explanation:

To solve the quadratic, use inverse operations to set it equal to 0.

$-5x^2+7x=-9\\-5x^2+7x+9=0$

To solve, use the quadratic formula and substitute a= -5, b= 7 and c= 9.

$x=\frac{-b +/-\sqrt{b^2-4ac} }{2a} \\\\x=\frac{-7 +/-\sqrt{7^2-4(-5)(9)} }{2(-5)} \\\\x=\frac{-7 +/-\sqrt{49+180} }{-10} \\\\x=\frac{7 +/-\sqrt{229} }{10}$
