Answer:
B. s = 13753
Step-by-step explanation:
s - 10000 = 3753
To find value of s, add both sides by 10000
s - 10000 = 3753
+10000 +10000
-----------------------------------
s = 13753
To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
The probability of drawing a black marble is 7/31 or .226 or 22.581%. To find the probability of these type of questions, add all together to get 31, then since there are 7 black marbles the probability would be 7/31.
12/3 = 4
4 cars per hour
4 x 5 = $20
20 x 8 = $160 for 8 hrs
15.050 < 15.500
notice that 500 is more than 50... so hope this helps a little bit !!!
