120 ÷ 80 = 1.5 and 1.5 = 3/2
So A is correct
Answer:
909 and 3267
Step-by-step explanation:
There are a total of 24 possible combinations using these 4 digits. This means that any one of these combinations subtracted from 4310 would be a possible solution. Therefore, we can create the following 2 combinations (below in bold) and subtract them from 4310 to get two possible solutions...
4310 - 3401 = 909
4310 - 1043 = 3267
Finally, we have two possible solutions which would be 909 and 3267
<span>y = 3x - 4
</span><span>(4,2); when x = 4; y = 3(4) - 4 = 9 ........FALSE
(1, -1)</span>; when x = 1; y = 3(1) - 4 = -1 ........TRUE<span>
(-1, -7)</span>; when x = -1; y = 3(-1) - 4 = -7 ........TRUE<span>
(2, 2)</span>; when x = 2; y = 3(2) - 4 = 2 ........TRUE
answer
(1, -1)
(-1, -7)
(2, 2)
So what I would do is first multiply the mean by 4 and that is the total u need, 146.5, to have a mean of 36 and 5/8. Next I add the lengths given, which is 110.625, and then I would subtract it from 146.5 which is 35.875 which is 35 and 7/8. You can also check the answer by finding the mean of the 4 numbers and determining if it comes out to 36 and 5/8. The answer is C. Hope this helps!
