Answer:
∠DCF = 129°
Step-by-step explanation:
We assume that line CE is between lines CD and CF.
The angle sum theorem applies:
∠DCF = ∠DCE +∠ECF
∠DCF = 75° +54°
∠DCF = 129°
Given :
A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.
The same meal cost $15 a person with no fee at Good Eats.
To Find :
When does we cater become the better deal.
Solution :
Let , x is number of order .
Cost at cater , C = 12.5x + 30 .
Cost at Good Eats , G = 15x .
We need to find :
G > C

Therefore, after 12th order cater will be more value for money.
Hence, this is the required solution.
If you would like to simplify the expression (x - 8y) - (2x - 4y), you can do this using the following steps:
(x - 8y) - (2x - 4y) = x - 8y - 2x + 4y = -x - 4y
ax + by = -x - 4y
a = -1
b = -4
The value of b would be -4.
If you would like to simplify the expression (4x - 6) - (3x + 6), you can do this using the following steps:
(4x - 6) - (3x + 6) = 4x - 6 - 3x - 6 = x - 12
The correct result would be x - 12.
Answer: each 0.5 hour or 30 minutes they travel 1 mile
Step-by-step explanation:
so just keep adding 1 mile each 0.5 hour
First, identify the formula you will use.
sum of all scores / number of scores = 225.
(192 + 214 + 250 + x) / 4 = 225
192 + 214 + 250 + x = 900
x = 900 - 656
x = 244
