Answer:
percentage of interest = 22.6% (to one decimal place)
Step-by-step explanation:
actual price paid (including interest) = 429, out of which
interest = 429-350 = 79
Percentage of interest out of actual price paid
= 79/429* 100%
= 22.6%
Remember
we can do anything to an equation as long as we do it to both sides
try to isolate the variable
you have 2 types
x+b=c
x/b=c
fior the first type, minus b from both sides to get
x=c-b
for the second, multiply both sides by b to get rid of the fraction to get
x=cb
also remember that -x times -1=x
b.add 25 to both sides
-a=20
multiply -1
a=-20
c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32
d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150
e. multiply both sides by 12
-l=144
multiply b y-1
l=-144
Answer:
minimum value of z is 0
Step-by-step explanation:
if x and y both equal zero, then the value of z is zero, which is your answer.
Its the 2nd one becuase 2(-1)+2=0 witch is greater than -4.
