Answer:
214
Step-by-step explanation:
A circle is 360 degrees
Arc EF is 146 degrees
EF + EDF = full circle
146 + EDF = 360
Subtract 146 from each side
146-146 +EDF = 360-146
EDF =214
Answer:
6:41
Step-by-step explanation:
We know that the number of students going on the field trip is 6.
To find the total number of students, add the number of students going on the trip and the number of students staying at the school: 6 + 35 = 41
So the ratio of the number of students going on the field trip to the total number of students is 6:41
Number of cookie boxes bought by James = 5
Number of cakes bought by James = 2
Cost of each cakes = $4
Total bill paid by James = $28.50
Let us assume the cost of the each boxes of cookies = x
Then
5x + (2 * 4) = 28.50
5x + 8 = 28.50
5x = 28.50 - 8
5x = 20.50
x = 20.50/5
= 4.10
So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10
X+y=6
2x+y=4
solve the both
x+y=6
- (2x+y=4)
-x = 2
x=-2
substitute the value of x in x+y=6
-2+y=6
y=6+2
y=8
therefore the answer is (-2,8)
