Number 14: When looking at the table, the x has an increase of 3 while the y is an increase of 6. We need to divide the difference of the y by the difference of x. 6/3=2 So, that means every time x changes by one, y changes by 2. At 9, the corresponding number is 15. Since we’re to 10, the corresponding number has to be 17. So, the answer is b, 17.
Number 15: This problem deals with perimeter. No matter what, the perimeter is 12 feet. To find perimeter, it is 2l+2w=12 We have the length, so let’s put it in. 2(4.5)+2(w)=12 Let’s multiply. 9+2w=12 We need w by itself, so we need to subtract 9 from both sides then divide by 2. 2w=3 3/2=1.5 The answer is A, 1.5.
