double the unknown number then add 4.7
X= -14/3 !
hope this helps
Step-by-step explanation:
<h3>Given:</h3>
<h3>To prove:
</h3>
<h3>Solution:</h3>
<u>CM⊥AB - given, therefore</u>
- ∠AMC = 90° and ∠BMC = 90°
<u>Then</u>
- Side CM is common, therefore is congruent to itself
<u>So we have congruent two angles and a side between them on triangles AMC and BMC:</u>
- △AMC ≅ △BMC as per ASA congruency theorem

Step-by-step explanation:
Answer:
C = 600 + 50s
Step-by-step explanation:
Let s be the number of students that go on the trip.
Let C be the cost.
The bus costs $600 and the entry fee (for each student) costs $50.
The cost for the trip will be the sum of the cost of the bus and the ticket for every student that goes on the trip.
This implies that the total cost for the trip will be:
C = 600 + 50(s)
C = 600 + 50s
