All of these only require a single operation before you get x alone. for example:
x - 2 = 6
compared with
2x = 6
for the first one, you add two and get x = 8. for the second one, you divide by 2 and get x = 3. they're both a single step, as the name "one-step" equations tells you, and you only have to divide, multiply, add, or subtract one value.
2•(1/4)^(2-1)= 2•(1/4)= 1/2
2•(1/4)^(3-1)= 2• (1/4)^2 = 2•1/16=1/8
Y=6x (1)
y=5x-7 (2)
Substitute y into (2)
(6x)=5x-7 -- subtract 5x from both sides
x=-7
Sub x into 1
y=6(-7)
y=-42
x=-7
y=-42
11,400 seconds
You would take 3 hours to minutes which is 180 then add the following 10 minutes and convert it to seconds.
No area is shown. So befoe sam divided it,
the area of tge original rectangle was . . .
8 x 0 = zero .
