Answer:
Onaje is correct.
Step-by-step explanation:
To start, total up how many shirts we have, and multiply them by <em>t</em>. Since they are the same price, we now have a total for how many shirts they bought. This proves the second and third equations that they wrote. If you take the easy way and just add them, you'll still have 25<em>t</em>, making Onaje's expression correct.
EDIT: Just saw you need why it's incorrect for Paula, just hold on.
So for Paula, it's simple why she is incorrect. If you look at the third equation she wrote, she's adding 25 to 2t, which is completely incorrect, and will come up with a different result than 16t + 9t.
Hope this helps.

Answer:
a) 10/3
Step-by-step explanation:
2x - 6 + 5x = 1/3 x - 9 + 2y
7x - 6 = 1/3 x - 9 + 2y
or
2y = 7x - 1/3 x - 6 + 9
2y = 21/3 x - 1/3 x + 3
2y = 20/3 x + 3
y = 20/6 x + 3/2
y = 10/3 x + 3/2
Y = mx + b where m = slope
In this case slope m = 10/3
Answer:
13.87
Step-by-step explanation:
Three friends went out to eat dinner the bill came to 35.60. This means that the total bill for the dinner was 35.60.
The original bill was 35.60. If they shared the bill equally, the amount that each of them would pay would be
Total bill / number of friends
It becomes 35.60/3 = 11.87
The three friends also decided to leave a 6.00 tip and it was sent equally. This means that each friend would pay a tip of
6/3 = 2. ( total amount of tip paid divided by the number of friends)
Therefore, the total amount that each has to pay = amount each paid for the bill + amount that each paid for the tip
= 11.87 + 2 = 13.87
Answer:
(p - 8)(p - 9)
Step-by-step explanation:
We need 2 numbers whose product is + 72 and whose sum = -17.
They are -8 and -9
