The correct answer among the choices listed above is the second option. <span>The following system of equations is equivalent. This is because when written in the same form, one equation will yield to the same equation as the other.
</span>y = -1/3x +2/3
<span>2x + 6y = 4
</span>6y = 4 - 2x
y = 2/3 - 1/3x
<span>y = -1/3x +2/3 </span>
Answer:
Option A, 
Step-by-step explanation:
<u>Step 1: Determine the numbers that are multiples of 3</u>
8 → Not a multiple of 3
9 → Multiple of 3
14 → Not a multiple of 3
19 → Not a multiple of 3
25 → Not a multiple of 3
34 → Not a multiple of 3
38 → Not a multiple of 3
<u>Step 2: Determine the probability of chosing a multiple of 3</u>
Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:


Answer: Option A, 
15. 1/2 base * <span>hight ,</span> 1/2 * 11 * 6 = the answer is 33 cm^2
16. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. So the answer is 155.
17. <span>The mean is the usual average, so I'll add and then divide. (33+25+42+25+31+37+46+29+38) / 9 = 34
18. You have to draw a plot.</span>
