Answer:
keiko- x
imelda- x+ 36
Sarah- x- 38
Step-by-step explanation:
- keiko is x since we have not been given his number of boxes.
- because imelda's number of boxes was 36 <em>more </em><em>than </em>keiko's, you will add the x which is for keiko and 36 for imelda(x+36).
- and sarah's number of boxes will be x-36 because we have been told her number of boxes is 38 <em>fewer </em><em>than </em> keiko's.

Answer:</h2>
d. <u>r = 1/6 s</u>
<h2>
Step-by-step explanation:</h2>
Taking the first set,
s=1 and r=1/6
Establishing a relationship between 1 and 1/6,
1 = 6*1/6
Therefore, it can be written as, s = 6*r
Thus, 1/6 s = r
Similarly, this is true for other sets.

A long session lasts 50 minutes.
Step-by-step explanation:
Let,
Duration of long session = x
Duration of short session = y
According to given statement;
3x+4y=270 Eqn 1
each long session lasts twenty minutes longer than the short session.
x = y + 20 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 7
Putting y = 30 in Eqn 2
A long session lasts 50 minutes.

Answer:
Below in bold.
Step-by-step explanation:
|-7-9x|=2
The left side is the absolute value of -7 - 9x, therefore
-7 - 9x = 2 or -7-9x = -2
-9x = 2 + 7
-9x = 9
x = -1
OR
-9x = -2 + 7
-9x = 5
x = -5/9.
