Answer:
a=-1.2
Step-by-step explanation:
5x-10=3x+a=12
let's first find x:
5x-10=12
add 10 to both sides:
5x=22
divide both sides by 5:
x=4.4
now that we know what x is, we can plug it back into the equation to find a:
3*4.4+a=12
first, simplify both sides:
13.2+a=12
then, subtract 13.2 from both sides:
and our answer is: a=-1.2
Answer:
0.03
Step-by-step explanation:
fraction = part/whole
= 27/900
= 3/100
=0.03
decimal value = 0.03
90 sides give us 90 angles
sum of all inside angels is (n-2) * 180 deg. where n is number of angels
so one inside angle is
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.
measure of exterior angle is 360 - 176 = 184 deg.
For the answer to the question above, the power of "y" doesn't influence descending order for x even if it is higher than power of x.
Unordered polynomial is
7x3y3 + 4 - 11x5y2 - 3x2y
Polynomial in descending order looks like this
-11x5y2 + 7x3y3 - 3x2y + 4
Degree of the second term is 5 ( because of x5 )
