17 and 5

Step-by-step explanation:

Interesting question!

Turn both sentences to equations:

$a=4b-3\\a-2b=7$

a is the first number, and b is the second number.

A system of equations! A graphing calculator will do the work:

Answer:

With replacement

$probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}$

$probability \ of \ spade \ then \ red\ card\ without\ replacement =$ $\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}$

Without replacement

$probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}$

$probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}$

Sunrise Trail is three and a quarter miles one mile equals 5280 feet what is the length in feet of the trail

kifflom [539]

So 1 mile= 5280 feet. So first take 5280 divided by 4 (because we have a quarter mile) = 1320.
Then do 5280 x 3 (because we have three miles)= 15840 feet
then take 1320 + 15840= 17160 feet
The trail is 17,160 feet long
