Answer:
RS = 5
Step-by-step explanation:
Since R is between Q and S , then
QS = QR + RS , that is
6x - 3 = 3x - 2 + 2x + 1
6x - 3 = 5x - 1 ( subtract 5x from both sides )
x - 3 = - 1 ( add 3 to both sides )
x = 2
Then
RS = 2x + 1 = 2(2) + 1 = 4 + 1 = 5
Answers: Choice A and Choice E
0.82B and B-0.18B
========================================================
Explanation:
B is the cost of the game (some unknown amount). Subtract off 0.18B to indicate a 18% reduction in the price. That's how we get choice E.
Simplifying choice E leads us to choice A. Notice that 1 - 0.18 = 0.82; which represents 100% - 18% = 82%. After the discount, Bo is paying 82% of the original price.
Side note: Choice B indicates an 18% increase. Choices C and D don't represent percentage decreases (rather they're decreasing by a fixed amount regardless of what B is).
Answer:
Step-by-step explanation:
13500/3 = 4500
4500 x 2 = 9000
Answer:
the lease common multiple is 8
The number of adults = 41
The number of children = 97
Step-by-step explanation:
Let x be the number of adults and
y be the number of children
then according to the given conditions

From equation 1:
x = 138-y
Putting in equation 2

Dividing both sides by -7

Putting y = 97 in equation 1

Hence,
The number of adults = 41
The number of children = 97
