<span>The equation models this situation 10x+15y=980
Where x represents number of basic washes and y represents the number of ultimate washes.For total sales we want to add the two basic given data.Therefore basic wash and ultimate wash which is equal to total sales on that day.</span>

Answer:
c) x² + 3x + 1
Step-by-step explanation:
-3 / 1 6 10 3
<u> </u><em><u>-3</u></em><u> -</u><em><u>9</u></em><u> -</u><em><u>3</u></em><u> </u>
1 3 1 0
Answer: x² + 3x + 1
Step 1: Carry down the first number 1 as it is
Step 2: Multiply 1 by -3 (1 * -3 = -3) and write this -3 under the next number 6 and then add. 6 + (-3) = 3
Step 3: Multiply this 3 by -3 (3 * -3 = -9) and write this -9 under the next number 10 and then add.10 +[-9] = 1
Step 4: Multiply 1 by -3 (1 * -3 = -3) and write this -3 under the next number 3 and then add. -3 +[-3] = 0
Do you know what a square root is?
A cube is based on the same concept but is 3x the number itself to receive the value.
For the question, the answer is 0.027 because 0.3 * 0.3 * 0.3 is 0.027
50 yards for 1 lap
50 yards x 18 laps = 900 total yards
now divide the amount he swam by the total amount he wants to swim:
738 / 900 = 0.82 = 82%
Answer is B
