Answer: 2m + c =4
Step-by-step explanation:
Let m = Number of multiple-choice questions
c = Number of constructed response questions
For Summer,
Total marks = 12m + 4c
For kerry,
Total marks = 10m+3c
Summer scored eight points more than Kerry implies
12m + 4c = 4+(10m+3c)
⇒ 12m + 4c = 4+ 10m+3c
⇒ 12m + 4c - 10m-3c =4
⇒ 2m + c =4
Hence, required equation that shows how much each multiple-choice question (m) and each constructed response question (c) is worth. :
2m + c =4
Answer:
64 + x + 85 + x + 55° = 180°
2x + 204 = 180°
Answer:
Step-by-step explanation:
Use the circle equation,
Plug in the center and radius:
Simplify:
So, the equation is
Answer:
CD = 3
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
CB × CA = CD × CE , that is
4 × (4 + 6.5) = CD × 14
4 × 10.5 = 14CD
42 = 14CD ( divide both sides by 14 )
CD = 3
