-4
Because 15x-7x= 8x
8x+5x= 13x
13x= -52
-52 / 13= -4
x = -4
15/5 is 3
So then you change the equation to be 12=15z-3 ( don’t forgot the negative sign)
Move the constant to the right side and change the sign
-15z= -3 -12
-3-12 is -15
Divide -15z= -15
Your final answer will be z= 1
Answer:
64
Step-by-step explanation:
1/7 and 3/14......common denominator is 14
2/14 = 3/14
cross multiply
(14)(3) = (14)(2)
42 = 28...not correct...no, this does not form a proportion
little tip ** proportions are nothing but equivalent fractions and 1/7 does not equal 3/14...now if it would have been 1/7 and 2/14...then it would have been a proportion
Answer:
To determine Morgan's new balance at the end of the month?
it will be the sum of its, monthly percent amount, expense balance and the fixed monthly payment.
Credit limit = $1900
Annual percent rate = 14.99%
Monthly percentage rate = 14.99/12 =1.249%
which amount to = $300x1.249%/100 = $3.747
Minimum monthly payment = $300x4/100 = $12
Purchase balance = $300
Morgan's new balance at the end of the month = $23.734+ $12+$300
= $315.757 =31575cents
