4x+10=90
4x=80
x=20
Why 90°? This is because the angle subtended in a semi-circle to the circumference is 90°.
Answer:
Step-by-step explanation:
Let x represent the cost of one package of tulip bulbs.
Let y represent the cost of one bag of daffodil bulbs.
Ava bought 6 packages of tulip bulbs and 12 bags of daffodil bulbs for a total of $198. This means that
6x + 12y = 198- - - - - - - - - - - - -1
Grace spent $254 buying 14 packages of tulip bulbs and 12 bags of daffodil bulbs. This means that
14x + 12y = 254- - - - - - - - - - - - 2
Subtracting equation 2 from equation 1, it becomes
- 8x = - 56
x = - 56/-8
x = 7
Substituting x = 7 into equation 1, it becomes
6 × 7 + 12y = 198
42 + 12y = 198
12y = 198 - 42
12y = 156
y = 156/12
y = 13
Answer:
B
Step-by-step explanation:
I think it is three-fifths because the total is 5 and after the A', the length is 3.
So the answer is Three-fifths
