Answer:
A: x + y = 55; y - x = 25
B: 15 minutes running
C: no
Step-by-step explanation:
<h3>Part A:</h3>
The two equations relate to the total number of minutes, and to the difference specified in the problem statement.
x + y = 55 . . . . . . total time is 55 minutes
y = x + 25 . . . . . . dances 25 minutes longer
__
<h3>Part B:</h3>
We can substitute for y in the first equation to find the value of x, the time spent running.
x + (x +25) = 55
2x = 30 . . . . subtract 25
x = 15 . . . . . . divide by 2
Jackie spends 15 minutes running each day.
__
<h3>Part C:</h3>
The value of y from is found using the second equation:
y = x +25 = 15 +25 = 40
Jackie <u>will not spend 45 minutes dancing</u> if she meets the requirements on times.

Answer:
−9.333
Step-by-step explanation:
(1): "6.75" was replaced by "(675/100)"
(675/100)+3/8*x-((13)*1/4)=0
Simplify 1/4
675 3 1
(———+(—•x))-(13•—) = 0

New balance=previous balance+finance charge+New transaction
First we need to calculate the finance charge in order to find the new balance
Finance charge=2,103.24×(0.144÷12 months)
=25.24
New balance
2,103.24+25.24+280
=2,408.48
Hope it helps!
