3t-1=8
3t=8+1
3t=9
3t divide by 9
Will give you 3
So your t value would be 3
Explanation: you would have to bring the -1 over to the 8, making the 1 positive. Then you would add up 8 nd 1.
And just divide the two numbers so 9 divide by 3. And you would have your answer T=

The expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).
<h3>What is the expression that represents the phrase?</h3>
The difference of a number and 5 is given by:
x - 5.
As we don't know the number, hence we call it x.
Twice that is:
2(x - 5).
Hence the expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).

Answer:
32 cubic feet
Step-by-step explanation:
To know the volume of a figure we have to calculate the area of its "base" and then multiply it by its height.
In this case we have a rectangular hole that has an area of 8 square feet.
As we said before:
Volume = Area x height.
If we substitute the value of the area of the rectangle and the height (or depth in this case) we would get:
Volume = 8 x 4 = 32 cubic feet.
Thus, the volume of John's hole is 32 cubic feet.
A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b
