You are correct. The answer is C, 11 units
The ordered pairs are (3,6) and (14,6)
The x numbers are the same. The y numbers are different.
So, you would subtract 3 from 14 (14-3) to get the answer of 11 units.
Hope this helps you! (:

Answer:
6
Step-by-step explanation:
I'm pretty sure it's 6, sorry if it isn't
To divide fractions, you would multiply the reciprocal. What this means is that you would flip the fraction, so if you flip the fraction 35/48, that is 48/35. And because we flipped it, we now need to multiply it with the other fraction. This would be
. Now we can use cross multiplication to simplify. We can see that 48/24 is 2, and 2/1 = 2. So we can replace 48 with 2, and 24 with 1. Now we can also see that 35/7 = 5, and 5/1 = 5. So we can replace 35 with 5 and 7 with 1. So our new fractions are
. And therefore your answer is D. 2/5. Hope this helps. Feel free to ask more questions, or ask questions about my explanation.
Answer:
15: Yes, no, yes, yes, no; 16A: C = ($0.29)X + ($1.45)Y + ($2.50)Z; 16B: Yes
Step-by-step explanation:
For question 15: We need to multiply the widths and lengths given to see if they equal the area we are trying to achieve. Therefore, some of them work, and some do not.
For question 16:
Part A: We'll set a variable for the number of each supply she can buy. Pencils will be represented by X, pens by Y and Notebooks by Z, and we'll represent total cost by C. The total cost will therefore be represented by C = ($0.29)X + ($1.45)Y + ($2.50)Z.
Part B: We'll plug the numbers of items she wants to buy into our formula and see if it comes out to less than $20. So in this case C = ($0.29)(3) + ($1.45)(4) + ($2.50)(2). Therefore, C = $11.67, which is less than $20, so she can afford her school supplies.
