Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
-17 is the correct answer:)
answer:
turkey sandwich = $6.50
salad = $5.50
explanation:
first, write equations to represent the problem.
4t+2s=37
t-s=1
then, you can use elimination, then algebra.
2t-2s=2
6t=39
3t=13
Answer:
A, B and C (close examination)
Step-by-step explanation:
A. 15m3 - 6m = 3m(5m2 - 6m)
B. 40m6-4=4(10m6-1)
- 0 = 0
- All real numbers are solutions
C. 6m2+18m=6m2(1+3m)
D. 32m4+12m3(8m+3)
This is tough one but I will explain this problem by close examination:
The problem is looking for an equation that have the variable m by itself
D is out of the picture because the equations does not have m by itself
Equation B's answer is that all numbers are solutions meaning any m value you put will become the same. (Similar to Infinite Solutions)
By close examination, The answer are A, B, and C.
