Answer: 48 books
Step-by-step explanation: Start by converting 60% to a decimal/fraction (60/100). From there, you can multiply it by the total (80) to get the answer.
Multiply 300 times 5. you know that 3 times 5 equals 15. 15 plus 2 zeros is 1500. 1500 is the estimated answer
Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.
Answer:
SF = 7/3
Step-by-step explanation:
Like the problem hint says, you want to put the new coordinate over the old one to find the scale factor. We'll use both x and y.
-7/-3 = 7/3
14/6 = 7/3
Therefore, the scale factor is 7/3.
