Answer:
Step-by-step explanation:
2) 8=n+3/-2
we cross multiply
n+3=8*(-2)
n+3= -16
n= -16 - 3
n= -19
lets check if we are correct
8=-19+3/-2
8= -16/-2
-16/-2=8
4) 9=x/2+6
we first calculate the fraction
x/2+6
L. c. m is 2
x/2+6/1=4x + 8/2=12x/2
2 times 2=4 plus x = 4x
2 times 1 =2 plus 6= 8
thats how i got 4x + 8/2
back to the question
9=12x/2
cross multiply
12x=9*2
12x=18
x=18/12
we will use 2 to divide it
9/2
3 will divide
3/2
x=3/2
0.6 (y + 3) = 4.8
y+3 =4.8/0.6
y + 3 = 8
y = 8 - 3 = 5
y = 5
Answer:
All you have to do is think...and boom u got the answer
We know that
<span>m Arc DC = 32°
if </span><span>∠AED = 98°
then
</span>m Arc AD = 98°-----> by central angle
therefore
m Arc ABC=360°-[m Arc AD+m Arc ]----> 360°- [98°+32°]---> 230°
the answer is
m Arc ABC = 230°
