-2 + 3b = 5b - 2(2b + 3) Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6 Combine like terms
-2 + 3b = b - 6 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6 Combine like terms
-2 + 2b = -6 Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2 Combine like terms
2b = -4 Isolate b by dividing both sides by 2
b = -4/2 = -2
Answer b = -2
Answer:
A: Y<1/2x+2
Step-by-step explanation:
The shaded area is under the line, which indicates that Y is less than or equal to. The +2 in the inequality tells you where the y-intercept is (where the line goes through the y-axis). The 1/2 in the inequality tells the slope of the line (up 1, over 2) thus 1/2. So the answer is A

It is not a very tough question as it has all the information's required to find the necessary answer. It is already given that 82 1/2% of a certain number is 330. It is required to find the unknown number. So we have to create an equation with a single unknown number.
Let us assume the number to be = x
then we can easily write the equation as given below.
82 1/2% x = 330
(165/4)%x = 330
(165/400)x = 330
x = (330 * 400)/165
= 2 * 400
= 800
So the unknown number is 800.
Answer:
C. Hollow cone frustum
Step-by-step explanation:
Revolved it in my head, because the line isn't touching the triangle it will be hollow, because the triangle has a slope the shape will taper.
