The GCF is 6 so divide both by 6
12/11
That's the answer :)

72/66 greatest common factor is 6 so iffy would be 12/11 which is your answer.:)

Gianna is substituting t = 2 and t = 7 to determine if the two expressions are equivalent.5(2t+3) 5t+25
Which statement is true?
A. Both expressions are equivalent to 35 when t=2.
B. Both expressions are equivalent to 85 when t=7
C. Both expressions are equivalent to 60 when t=7
D. The expressions are equivalent.
PLEASE HELP!!!!

Answers

Answer: A. Both expressions are equivalent to 35 when t=2.

Step-by-step explanation:

Given: Gianna is substituting t = 2 and t = 7 to determine if the two expressions are equivalent.

At t=2

$5(2t+3)=5(2(2)+3)=5(4+3)=5(7)=35$

$5t+25=5(2)+25=10+25=35$

Therefore, both expressions are equivalent to 35 when t=2.

At t=7

$5(2t+3)=5(2(7)+3)=5(14+3)=5(17)=85$

$5t+25=5(7)+25=35+25=60$

Hence, A is the write option.

Look at the last number in the decimal.

12.66
12.63

Compare 6 and 3. 6 is larger so therefore 12.6666666 is larger. (You also need to compare the tenths place too, but these happen to have the same tenths place, .6.

A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots? A.The expression is 3p. It takes 30 minutes to shape and fire 10 pots.B.The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.

D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answers

Answer:

D. The expression is $3p+10$ . It takes 40 minutes to shape and fire 10 pots.

Step-by-step explanation:

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take $3p$ minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

Thus, the expression for the time taken to form one batch of pots = $3p+10$

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = $3* 10+10$ = 30+10 = 40

That is, 'It takes 40 minutes to shape and fire 10 pots'.

Thus, option D is correct.

3p to shape and 10 minutes to fire
= 3p + 10
3x10 + 10 = 40 minutes for a batch of 10 pots
therefore D is the correct answer
