Answer:
181/20
Step-by-step explanation:
Answer:
function= 2nd,6th
not a function=1st,3rd,4th,5th
Step-by-step explanation:
because in graphing a function, there should only be one y for the x. 2 or more y's in one x is considered as not a function
If the number of cheeseburgers sold was two times the number of hamburgers sold we know 1/3 of the burgers sold were hamburgers. So 240/3=80. This means 80 hamburgers were sold and 160 cheeseburgers were sold
Answer:
- 78.33°
- 71°
Step-by-step explanation:
1) The sum of angles in a triangle is 180°, so ...
(x +3)° +(x +24)° +(x -10)° = 180°
3x +17 = 180 . . . . . . . . divide by °, collect terms
3x = 163 . . . . . . . . . . . .subtract 17
x = 54 1/3 . . . . . . . . . . .divide by 3
m∠B = (x +24)° = (54 1/3 + 24)°
m∠B ≈ 78.33°
__
2) An exterior angle is equal to the sum of the opposite interior angles.
m∠ACD = m∠A + m∠B
(3x -10)° = (x +9)° + 105°
2x = 124 . . . . . . . . . . . . . . divide by °, add 10-x to both sides
x = 62 . . . . . . . . . . . . . . . . divide by 2
m∠A = (x +9)° = (62 +9)°
m∠A = 71°
