Answer is c) 2x - 15 because x is Valerie's grade
Allie's grade is <span>taking Valerie's grade, multiply it by 2 and subtract 15</span>
The Triangle Sum Theorem states that the sum of the angles of a triangle equal 180°.
Therefore,
45° + 62° + k = 180
107° + k = 180
k = 73°
The value of k is 73°
Answer:
I agree with Elena
Step-by-step explanation:
Ants have 6 legs. Elena and Andre write equations showing the proportional relationship between the number of ants, a, to the number of ant legs, v.
Elena writes a = 6 times v
Andre writes v =1/6 times a.
Mathematically
The number of ants a is directly proportional to the number of legs
=a ∝ v
Because if
1 ant = 6 legs
2 ants = x legs
x = 6 legs × 2
x = 12 legs
The number of ants is directly proportional to the number of legs
Therefore, Elena is correct and Andre is wrong.
