Step-by-step explanation:
Hello :
(-6a)-(-3a) =(-3a)-(0) = (0)-(3a) = (3a)-(6a) = -3a (arthmetic<span> sequence, the common - diff is : d= -3a the first term is : U1 = 6a
</span><span>a general rule for the n th term is : Un =U1+(n-1)d
Un = 6a +(n-1)(-3a) =
Un = 6a -3an+3a
</span>Un = -3an +9a
Answer:
106°
Step-by-step explanation:
The angle CAB is an inscribed angle of the arc mBC, so we have that:
mBC = 2*CAB
So we have that mBC = 2*37 = 74°
The segment AC is a diameter of the circle, so mAC = 180°
The ? angle is the arc mAB, which is the difference of mAC and mBC, so:
mAB = mAC - mBC = 180 - 74 = 106°
So the ? angle is 106°.
Answer:
x=16
Step-by-step explanation:
multiply the 3 to cancel it out
now you have x+2=18
then you subtract by 2 to cancel it out
so now you are left with x=16
1 5/8 - 3/8 = 1 1/4
Subtract the numerators because the common denominators are the same and leave the whole number to make 1 2/8. To simplify it you divide it by 2 because that's the highest number that can go into both numerator and denominator to make is 1 1/4.
