So, it's 3 and 1/2 pounds, right? So, since the 3 pounds is already written, you just need to find out how many ounces. There are 16 ounces in a pound, so what is 16 divided by 2? Then, you just take 3 and put 3 pounds x ounces. To explain it you could use what I said if you'd like! :)
The answer would be the second option because 49/10 is equal to 4 9/10 which is greater than 7/10
y = mx + b
The product of slopes of perpendicular lines is -1. The slope of the given line is 2, so the slope of the perpendicular line is -1/2.
y = (-1/2)x + b
Now use the given point to find b and finish from here.
-5 = (-1/2)(2) + b
b = ?
Answer:
27 years
Step-by-step explanation:
Let Holly's age be h and Aunt's age be a. We can setup 2 equations and solve.
1. 
2. a - 15 = h
We can plug in equation 2 into equation 1 to solve for aunt's age:
Holly's aunt's age is 27
