Answer:
a=1
Step-by-step explanation:
Because x-1 is factor of f(x)
for x1=1, f(1)=0, then
f(1)=5*1^3+a*1^2-4*1-2=0
5*1+a*1-4-2=0
5+a-6=0
a-1=0
a=1
There are 16 girls and 12 boys which means the ratio of number of girls to the numbers of boys in her class is 16:12 and 4:3 when simplified.
9.06. It cannot be any other number because it must be between 9.04 and 9.15 and no other number has a 6 (9.04, 9.05, 9.06, 9.07, 9.08, 9.09, 9.10, 9.11, 9.12, 9.13, 9.14, 9.15).
Answer:
if your solving for N= 1/18x + -1/6y
if your solving for X x=18n+3y
Step-by-step explanation:
Let's solve for n.
x−3y=18n
Step 1: Flip the equation.
18n=x−3y
Step 2: Divide both sides by 18.
if your solving for y then its
Step-by-step explanation:
just count off the positions after the decimal point.
they go with decreasing negative exponents of ten.
the first position is 1/10.
the second 1/100.
the third 1/1000.
the fourth 1/10000
the fifth 1/100000
and that is how we can easily convert such decimals into fractions.
0.63333 = 63333 / 100000
or were you looking for the infinite decimal ?
that would be 1.9/3 = 19/10 / 3 = 19/30
I found this by simply suspecting that there is a division by 3 involved (due to the 3333333 repeating pattern).
so, by multiplying 0.63333 by 3 we get 1.9.
1.9 = 19/10
and then dividing by 3 gives us 19/30
