The sponsors of the marching band provided 128 sandwiches for a picnic. After the picnic, s sandwich’s are left.

1 answer:

7 0

A. 128-x=s ( x would be the sandwiches handed out and since we dont have a value we cant know exactly what the value is)

B . 128-x=15 so this means there were 113 sandwiches handed out
(subtract 15 from 128 and you get the value of sandwiches handed out)
Make sense? Hope i helped :)

Three rational numbers between 5/31 and 6/31

Ludmilka [50]

Answer:

$\dfrac{26}{155}$ , $\dfrac{27}{155}$ , and $\dfrac{28}{155}$ .

Step-by-step explanation:

What is a rational number? By definition, a rational number can be represented as the fraction of two integers.

The goal is to find three fractions in the form $\dfrac{p}{q}$ between $\dfrac{5}{31}$ and $\dfrac{6}{31}$ .

$\dfrac{5}{31} < \dfrac{p}{q} < \dfrac{6}{31}$ .

At this moment, there doesn't seems to be a number that could fit. The question is asking for three of these numbers. Multiple the numerator and the denominator by a number greater than three (e.g., five) to obtain

$\dfrac{25}{155} < \dfrac{p}{q} < \dfrac{30}{155}$ .
