Answer:
7 miles
Step-by-step explanation:
Let's call the distance between the library and police station x. Then, the distance between the police station and fire station would be 3 less than twice x. Twice means multiply by 2 so twice x is 2 * x = 2x and 3 less than means that you subtract 3 so 3 less than 2x is 2x - 3. Now, we know that x = 5 so all we have to do now is substitute x = 5 into 2x - 3, therefore, the answer is 2 * 5 - 3 = 7 miles.
Estimation....
20% off means u r paying 80%. 349.99 rounds to 400.
80% of 400.....turn percent to decimal....." of " means multiply.
so 0.8(400) = 320 <== ur estimate
The 2nd option because once you distribute the "2" you're left with 2+4x, and when try moving the "x's" to the same side they cancel out. and 3 is NOT less than or equal to 2
