Answer:
12 and 52
Step-by-step explanation:
Let x and y be the 2 integers with x > y, then
x + y = 64 and
x = 3y + 16 ( 16 more than 3 times the smaller )
Substitute x = 3y + 16 into x + y = 64, that is
3y + 16 + y = 64
4y + 16 = 64 ( subtract 16 from both sides )
4y = 48 ( divide both sides by 4 )
y = 12 and x = 3(12) + 16 = 36 + 16 = 52
The 2 integers are 12 and 52
Answer:
y - 4 = 4 (x + 3)
Step-by-step explanation:
Point-slope form is y - y1 = m (x - x1)
y1 is 4, m is 4, and x1 is -3
When you plug them in, you get: y - 4 = 4 (x + 3)
Note: (x - -3) becomes (x + 3)

Answer: At least 4/14 = 28.5%
Step-by-step explanation:
Select the location of a math book at the far end. The probability that the book next to it is a math book:
4 remaining math books, out of the 14 remaining books
In the middle, there are two potential spots adjacent to each book, so it could be higher - that’s why I say “at least” 4/14
Complementary angles add up to 90.
Say the complementary angle is A.
Angle A + Angle B = 90
Angle A + 60 = 90
Angle A = 30 degrees

Answer:
2.13% (rounded to nearest thousandth)
Step-by-step explanation:
You subtract 24 from 23.5 to get 0.5
Then you divide 0.5 by 23.5 to get 0.02127
Then you multiply that by 100 to get your percent error
