t/5 = 2.9
For the first step, I would multiply both sides by 5, to get rid of the fraction.
That will leave
t = 14.5
So with what you have on your screen, I would drag “x” and “5” to both sides of the equation.

Answer:
51
Step-by-step explanation:
Let s represent the number of seats in a row. Then the number of rows is (s-9) and the total number of seats is ...
s(s-9) = 2142
s² -9s +4.5² = 2142 +4.5² . . . . . complete the square
(s -4.5) = √2162.25 . . . . . . . . take the positive square root
s = 4.5 +46.5 = 51 . . . . . . . add 4.5
The number of seats in each row is 51.

the number of fence did Jon and Jim painted
Jon painted 1 – 4
Jim painted 5 – 12
<u>1 – 2 – 3 – 4</u> – <u>5 – 6 – 7 – 8 – 9 – 10 - 11 – 12</u>
- Jon - Jim
They painted a total of 12 fences. Because Jon started on paint in the first up
to 4th fence and Jim started to paint on the 5th going to
the 12th fence. Thus, the total of the fence they painted is still
12.
