Answer:
center = (3, 0)
radius = 2
Step-by-step explanation:
Standard equation of a circle:
(where (h, k) is the center of the circle and r is the radius)
Given equation:
Rewrite in standard form:
Therefore
- center = (3, 0)
- radius = 2
J=15b/10g
S=21b/g w/ the ratio 3/2 (15/10=3/2)
1) Form an equation (21/g=3/2).
2) Since you are trying to find the denominator, multiply 3/2 so that the numerators are the same (3×7=21 2×7=14).
3) The answer will be whatever the denominator is at the end.
The answer is there are 14 girls in Steven's class.
