3a plus 7. you group the whole numbers together and than the a's. so 3+4 is 7. 2a + a is 3a.
Answer:
60x + 25 + 60y
Step-by-step explanation:
60 times x plus 60 times y plus 25
Answer & Step-by-step explanation:
For this problem, we will use the distance formula.

For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.





So, the distance between (-3,1) and (1,5) is 5.657 units.
A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.
