Answer:
Step-by-step explanation:
Let d be the cost of a drink. The expression for the cost of the pizza and 4 drinks is
12.75 + 4d
If each drink costs $3, then
12.75 + 4(3) simpifies to
12.75 + 12 which equals 24.75
Answer:
B
Step-by-step explanation:
These lines are parallel so they have no solutions
The answer would be $56
The reason is you would do 80*.3(30% in decimal form) which would equal 24
24 is what is being taken off of the normal cost.
So you would then do 80-24 which would equal $56.
The answer is 2,2 i already do the exam :D
Answer:

Step-by-step explanation:
Given:
m ∠BDC = 20
m arc AB = 140
m arc CD = 120
Now, let the center of the circle be at point 'O'.
From the triangle AOB,
OA = OB (Radius of the circle)
∴ m∠ABO = m∠BAO = m ∠1
∵ m arc AB = 140
∴ m ∠AOB = 140 (Arc measure equals the angle subtended by the arc at the center)
Now, sum of all angles of a triangle is equal to 180. So,

Therefore, the measure of angle 1 is 20. So, the last option is correct.
