<span><span>A) Sally’s statement is sometimes true. The equations students write to support their answers will vary. Sample pairs of equations that support the answer “sometimes true” are as follows:
Sample addition equation:–6.2 + 5.71 = –0.49Sample subtraction equation:–3.96 – 2.84 = –6.8
</span></span><span><span>B) You can always change the order of positive and negative decimals when adding and you’ll get the same answer. When you change the order of positive and negative decimals when subtracting, you will get opposite answers.
C) Sally’s statement is true for addition of three positive and negative decimals but not true for subtraction. The equations students write to support their answers will vary. Sample pairs of equations that support the answer that Sally’s statement is true for addition but not subtraction are as follows:
Sample addition equation:
–6.2 + 5.71 + (–3.96) = –4.45Sample subtraction equation:2.84 – (–3.96) – (–6.2) = 13</span></span>
It can actually be done many ways. You must match up the corresponding sides.
For example, 24/20 and x/7 would work so would, 24/x and 20/7, and 7/20 and x/24. Most proportions are set up the same way. You just have to make sure to go in the same order for the two triangles. Sorry if it's confusing.
So let's use-20/7 and 24/x.
First, we multiply 7*24 and 20*x and we get 20x=168
Then we divide to get 168/20. X=8.4
