What problem there is no problem explain to me the problem
we are given
system of equations
First equation is
Second equation is
now, we can find augmented matrix
now, we can change it into reduced row echelon form
step-1: multiply the 1st row by 1/3
step-2:add -3 times the 1st row to the 2nd row
step-3:multiply the 2nd row by 1/4
step-4: add 2/3 times the 2nd row to the 1st row
so, we get
Answer is (5,-8)
Answer:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation
I = Prt (Where p=principle,r=rate,t=time)
I = p*0.08*1=0.08p
Step-by-step explanation:
Answer:
the answer is 12 attendees
Step-by-step explanation:
Let a=the attendees & Let d=the cost
if the budget is $97 and the cost of the gala is represented by the equation d=7a+13, substitute the $97 for d
d=7a+13
97=7a+13
now take subtract 13 from both sides
97-13=7a+13-13
since the 13 cancels out on the right side it'll now read:
84=7a
to get a by itself you now divide 7 from both sides getting a by itself
84/7=7a/7
12=a
so the answer will be 12
