Answer:
4800
Step-by-step explanation:
A day consist of 24 hours. Half of 24 is 12. 4 x 13 = 12 so 1600 x 3 = 4800.
First combine like terms
5+4= 9
1/4s-2/3s= -5/12s
-5/12s= 9
S= -21.6
Answer:
Step-by-step explanation:
<u>The depth readings are</u>
- The first mission: - 2 3/4 fathoms
- The second mission: - 2 5/8 fathoms
<u>Comparing the readings</u>
- - 2 3/4 = - 2 6/8 and - 2 5/8
<u>Absolute values compared</u>
Indicating the greater value on the first mission
As per above, the first mission was deeper
The goal of this problem is to determine all of the equations where x = 3 is a solution and this can be done by simply inputting the value 3 into any variable x that is seen into the expression. After, inputting the value we would simplify both sides and compare them. If the expression evaluates to true then x = 3 is a solution of the equation but if it evaluates to false then x = 3 is not a solution of the equation.
<u>Equation #1</u>
After inputting the value 3 into x, we added 4 to it and the final result that we got on the left side was 7 which was equal to the right side (7). Therefore, x = 3 is a solution of the first equation.
<u>Equation #2</u>
After inputting the value 3 into x, we did 3 divided by 9 and the final result that we got on the left side was 1/3 which was not equal to the right side (3). Therefore, x = 3 is not a solution of the second equation.
<u>Equation #3</u>
After inputting the value 3 into x, we subtracted 3 from 5 and the final result that we got on the left side was 2 which was equal to the right side (2). Therefore, x = 3 is a solution of the third equation.
<u>Equation #4</u>
After inputting the value 3 into x, we multiplied 3 by 8 and the final result that we got on the left side was 24 which was not equal to the right side (32). Therefore, x = 3 is not a solution of the fourth equation.
<u>Equation #5</u>
After inputting the value 3 into x, we subtracted 10 from 3 and the final result that we got on the left side was -7 which was not equal to the right side (7). Therefore, x = 3 is not a solution of the fifth equation.
Therefore, the only expressions that had a solution of x = 3 was the first and third equations since the final expression evaluated to true.
