Answer:
The stack is 
inches high.
Step-by-step explanation:
Given date:-
A stack of 7 crates means
1 stack=7 crates
Total number of crate=7
Height of 1 crate = 
Height of 1 crate =
inches
Height of 1 crate =
inches
To find height of stack=?
Now,
Height of a stack = Height of 1 crate 
Total number of crates
Height of a stack =
Height of a stack =
Height of stack = inches
Therefore the stack is inches high.
Each bottle serves 2 students. He needs to buy 14/2 = 7 bottles.
Answer:
The number is 9.
Step-by-step explanation:
Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.
80 - 3x = 5x + 8
First, let's add 3x to both sides.
80 - 3x + 3x = 5x + 3x + 8
80 = 8x + 8
Next, let's subtract 8 from both sides.
80 - 8 = 8x + 8 - 8
72 = 8x
Finally, let's divide both sides by 8.
72/8 = 8x/8
9 = x
<em>"x" is 9.</em>
<em>So the secret number is 9.</em>

Answer:
<2 ≅<4 with reason of vertical angle theorem.
Step-by-step explanation:
The vertical angle theorem states that two opposite (non-adjacent) angles formed by 2 intersecting lines have equal measure. In this problem, we are given that the angles are vertical angles. So the statement is that <2 ≅<4 with reason of vertical angle theorem.
Answer:
The slope of the line will change from negative to positive
Step-by-step explanation:
the equation is in the form of y=mx+c and m is negative. By multiplying m with another negative number it turns positive, thus slope changes from negative to positive
