Answer:
The flag pole is 28 feet
building is 168 feet
Step-by-step explanation:
building+flagpole= 196 feet
(use algebra)
let the flagpole be a
building will be 6a
<h2>
so 6a+a= 196</h2>
7a= 196 = 28
it means the flag pole is 28feet
28×6 is the building= 168 feet
Answer:
( x, y ) = ( 4, 1/3)
Step-by-step explanation:
x - 3y = 3
2x +9y = 11
1. substitute the value of x
x= 3 + 3y
2x + 9y = 11
2. solve equation
2 (3 + 3y) +9y = 11
3. substitute the value of y
y = 1/3
4. solve equation
x = 3 + 3 x 1/3
x = 4
5. check solution
(x, y) = ( 4, 1/3 )
check x ----> 4 - 3 x 1/3 = 3
check y ------> 2 x 4 + 9 x 1/3 = 11
for x----> 3=3
for y----> 11=11
Any whole number or number that can be written as a fraction
