Enrique+levi=386
enrique=221
subsitute
221+levi=386
subtract 221 frm botoh sides
levi=386-221
levi=165
levi has 165 cards
Answer:
The correct option is;
26.8
Step-by-step explanation:
The given parameters are;
The perpendicular bisectors of the sides of ΔMNP = Segments OQ, OR, and OS
Therefore;
in Segment MN, segment QM = segment QN, by definition of bisected line
Segment OQ = Segment OQ by reflexive property
∠OQM = ∠OQN = 90° by definition of perpendicular bisector
∴ ΔOQN ≅ ΔOQM, by SAS rule of congruency
Segment MO ≅ Segment ON by Congruent Parts of Congruent Triangle are Congruent, CPCTC
Segment MO = Segment ON = 26.8, by definition of congruency
Segment MO = 26.8

Answer:</h3>
<h3>
Step-by-step explanation:</h3>
In this question, we're trying to find the probability of a male that also studies Spanish.
In this case, we know that:
- There's a 40% chance of a student being a male
- Probability of a male that studies Spanish is 25%
With the information above, we can find the probability.
To find the probability, we would need to find how much of 40 is 25%.
To do this, we would multiply 0.4 (40%) by 0.25 (25%) to find our probability.
Solve:
The probability of a male that studies Spanish is 10%
Your answer would be A). 10%

Eva spent 2 hours tutoring and 6 hours clearing tables.
Let x represent the number of hours Eva worked tutoring and y represent the number of hours Eva worked clearing tables.
Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Hence:
y = 3x
-3x + y = 0 (1)
16x + 8y = 80 (2)
Solving equations 1 and 2 simultaneously gives:
x = 2, y = 6
Eva spent 2 hours tutoring and 6 hours clearing tables.
