Answer: 86 billion blocks
Step-by-step explanation:
Here, the total population is 2 billion,
Since, the blocks a person owe = 43
Thus,

= 
= 
Therefore, total blocks that sold their introduction = 86 billion.
Answer:
less than -7
Step-by-step explanation:
The product of -7 and 4 is -28, therefore it is less than -7.
The right answer is KI
This is a square prism. The bases of this type of prism are squares. In square prisms the opposite sides and angles are congruent. In this problem, we need to find which line segment is parallel to GE, so the right answer is KI as solved in the Figure bellow. Recall that parallel lines are lines that have the same distance apart called equidistant.
Answer:
The land area of Florida is 
Step-by-step explanation:
Let
x -----> the land area of Alaska in square miles
y -----> the land area of Florida in square miles
we know that
The linear equation that represent this problem is equal to
----> equation A
----> equation B
substitute equation B in equation A and solve for y

Remember that
Florida's land area is one-tenth the size of Alaska is the same as to say that Alaska's land area is ten times the size of Florida
Answer:
y = -4x+15
Step-by-step explanation:
y=x/4+5 may be presented as y = 1/4 x + 5, where a=1/4, b=5
swapping numerator and denominator and inserting an opposite sign in a=1/4, we have:
1/4 --------> 4/1 -------> -4/1 = -4
y = -4x+n
Point (2,7) means that x=2, y=7 substitute it to the equation y=-4x+n, calculate "n":
7=-4*2+n ------> 7=-8+n -------> 7+8 = n -------> 15=n
substituting n=15 to the equation y=-4x+n, we get finally y=-4x+15
