The answer would be 243 because 9 x 20 is 180 and 9 x 7 is 63 so 180+63 is 243
Answer:

Step-by-step explanation:
Given 
Let 
Interchange x and y

Solve for y, by first squaring both sides


Hence

The last choice is correct
Answer:
thanks I guess for the points
Step-by-step explanation:
AD = DC
y + 6 = 2y
y - 2y = -6
-y = -6
y = 6
DC = 2y = 2(6) = 12
answer
DC = 12
Given
Erin Lytle's gross pay is $26,300
She takes a married exemption of $4,000
state income tax rate is 5.5%
Find out she pay in state income tax
To proof
Gross pay = $26,300
married exemption = $4,000
Let the she pay in state income tax = x
5.5 % written in the simpler form
= 
= 0 .055
than the equation becomes
x = 0.055 ( 26300 - 4000)
x = 0.055× 22300
x = $1226.5
Erin Lytle pay in state income tax is $ 1226.5
Hence proved
