There is a 10 square feet difference between both decks.
x = -
isolate - 6x by subtracting 9 from both sides
- 6x = 16 ( divide both sides by - 6 )
x = = -
Answer:
(using substitution to solve the problem)
x=y-3
2x+y=12
2(y-3)+y=12
2y-6+y=12
3y=18
y=6
y=6
x=6-3
= (3, 6)
Step-by-step explanation:
using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.
i hope this helps :)
Answer:
a. 3 in.
Step-by-step explanation:
C = 6 π in
As you know circumference C= π d so d = 6
r = d/2 = 6/2 = 3
