First lets expand it
next we subtract 3T - 3 - 5 so it can be 3T - 8
next we add T to both sides
next we subtract 3T - 8 + T so it can be 4T - 8
next we add 8 to both sides
next we add 4 + 8 so it can be 12
then we divide both sides by 4
and lastly we reduce the fraction 12/4 and we have our answer.

A) T = 3

Hi there!

To solve this equation, you need to first use the Distributive Property on the right side.

4 - t = 3t - 3 - 5

Now, add like terms.

4 - t = 3t - 8

Then, move terms to their own sides.

(4 - 4) - t = 3t + (-8 - 4)

(-t - 3t) = (3t - 3t) - 12

-4t = -12

Now, divide both sides by -4.

-4t / -4 = -12 / -4

t = 3

The answer is A. 3.

Hope this helps.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

$y=\frac{x}{2}$

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
