Answer:
6x+1
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
RT is a perpendicular bisector of QS , then
Δ QRS is isosceles with 2 congruent legs , that is
QR = SR
7x - 22 = 4x + 5 ( subtract 4x from both sides )
3x - 22 = 5 ( add 22 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9
Then
RS = 4x + 5 = 4(9) + 5 = 36 + 5 = 41
To solve this problem, you can use a simple table to find the number of quarters and dimes:
type of coin I Quantity of coin I Value of coin (in amount of money)
------------------------------------------------------------------------------------------------------
dimes I x I 10x (a dime is equal to 10 cents)
------------------------------------------------------------------------------------------------------
quarters I 18-x I 450-25x (a quarter is equal to 25 cents)
After doing this table, you can form the equation:
10x + 450 - 25x = 420
-15x = -30
x = 2 dimes
18-x = 16 quarters
