To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.
You can also rule out the last two answers because they don’t have all the values.
P = pie
s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.
So the answer would be b s/2ph=r
Sorry that’s really badly worded and confusing, but I hope it helps.
Answer:
the angle is 245°
Step-by-step explanation:
that is a pentagon, (a shape with 5 sides)
we know 4 of the angles in the pentagon
the sum of those 4 angles is
58°+100°+112°+25°=295°
to find a shapes total amount of °, the equation is (n-2)x180°
(5-2)x180°
=540°
540°-295°=245°
x=245°
Graphs of proportional relationships pass through the origin because that's were the graph starts

The numbers represent an arithmetic progression.
The difference between terms is d=7.
S=a1+a2+...+an, a1=3 and
an=a1+(n-1)×d=3+17×7=122
S=(a1+an)n/2=(3+122)×18/2=125×9=1125
