For this you can just use a calculator and divide 2587.5 by 1150.

You should get $2.25 for the unit price. Hope this helped ^-^

irakobra [83]

Answer:

420 miles

Step-by-step explanation:

Distance = rate × time

Let's say that the distance is D and that John's speed is S. We know that:

D = S × 6

When Elliot drives at speed S+14:

D = (S+14) × 5

Setting D = D:

S × 6 = (S+14) × 5

6S = 5S + 70

S = 70

Therefore, the distance D is:

D = 70 × 6

D = 420

The distance from John's house to Miami is 420 miles.

Hey, how do I apply the digital root method to division? Thanks.

REY [17]

Step-by-step explanation:

The digital root of a number is the single digit that you get by adding all of the digits of the original number together. If the result of that is multiple digits, you add those digits together, repeating the process until you get a single digit. That digit is the digital root of the original number.

example given

2+5+7+5+2+0+6+4+3

How am I supposed to find ‘t’ here?

Softa [21]

You can solve for (T)

$y = - 16t {}^{2} + 400 \\ add \: both \: side \: by \: - 16t {}^{2} \\ - 16t {}^{2} = - 400 \\ divide \: both \: side \: by16 \\ t {}^{2} = - 25 \\ t = \sqrt{25} \\ t = 5 \\ \: also \: it \: can \: be \: - 5 \\ + - 5 \\ \\$

Hope this help :)
