Answer:
2 marbles
Step-by-step explanation:
Lana has 3 bags with x marbles in each bag totaling 12 marbles
3x=12
Divide by 3
3x/3 =12/3
x =4
Each bag has 4 marbles
Markus has 3 bags with y marbles totaling 18 marbles
3y =18
Divide each side by 3
3y/3 =18/3
y =6
Each bag has 6 marbles
6-4 =2
There are 2 more marbles in Markus' bags than in Lara's
Answer:
True
Step-by-step explanation:
A rational number means that the number can be expressed as a fraction, where you can have two whole numbers.
There is an equation which is 
Answer:
w = 400
Step-by-step explanation:
2400 = lw
Divide the area by two.
2400 / 2 = 1200
Now this cannot be the answer since the length is longer than the width.
Divide 1200 by two again.
1200 = 600
Notice there are two choices that are the closest:
w = 800
w = 400
The latter choice would be the answer since again, the length is longer than width in terms of measurement
Consider re-writing this formula as "A = pi*r^2." The backslash symbol "\" is unnecessary.
If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:
A/pi = r^2
Taking the square root of both sides, sqrt(A/pi) = r (r must be positive in this situation).
a)
his income must be "x" which is the 100%, and we would know that 0.2% of that is 12.37.
b)
his income must be "x" which is the 100%, and we would know that 2% of that is 12.37.
btw he's not making much either way.
