There are 15 sixteenths in 15/16.
1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y
Answer:
140
Step-by-step explanation:

Answer:
58.4
119.2
Step-by-step explanation:
Givens
Let one angle = x
Let the other angle = x + 58.4
Together they make 180 degrees.
Equation
x + x + 58.4 = 180 Collect like terms.
Solution
2x + 58.4 = 180 Subtract 58.4 from both sides
2x = 180 - 58.4
2x = 121.6 Divide by 2
x = 60.8
Answer
x = 60.8
x + 58.4 = 119.2
262,144 feet squared
This seems like a big number but area length times width. If the coaster is square then all sides are the same so the length and width are both 512 feet. This means you multiply 512 and 512. With that you get 262,144 feet squared.
