Answer:
c. 10
Step-by-step explanation:
Eliminate parentheses using the distributive property.
3(b+4) -2(2b+3) = -4 . . . . given
3b +12 -4b -6 = -4 . . . . . parentheses eliminated
-b +6 = -4 . . . . . . . . . . . . collect terms
-b = -10 . . . . . . . . . . . . . . subtract 6
b = 10 . . . . . . . . . . . . . . . . multiply by -1

The rules of equality require that any operation you perform on one side of the equal sign must also be done on the other side. So when we say "subtract 6", we assume you know that means "subtract 6 from both sides of the equation", for example.
Answer:

One pound bag cost $1.10
2 pound bag cost $1.98 which is .99 per pound
3 pound bag cost $2.85 which is .95 per pound
The more amount you buy the cheaper it is per pound.
The slide and the ladder made a right angle triangle with the ground. The angle that the slide made with the ground is labeled as
in the diagram below. We can use the trigonometry ratio to work out the size of the angle.
8.3 is the side opposite to the angle and 14.5 is the hypotenuse. We need to use the Sin ratio
° to the nearest degree
