15 because you have to dive 24 by 8, you get 3. Then you multiply 3 and 5 and you get 15
Answer: 3 1/3 hours
Step-by-step explanation:
Tina rate: 1/5 job/hr
Together rate: 1/2 job/hr
Tyra rate: 1/x job/hr
---------
Equation:
rate + rate = together rate
1/5 + 1/x = 1/2
2x + 10 = 5x
3x = 10
x = 3 1/3 hrs (time for Tyra to do the job alone)
Answer:
what is the expression
Step-by-step explanation:
Answer: without parentheses it'll be : -2x square 2 2x square 2 9x-2!
Step-by-step explanation: well to start with,Nothing will change when you solve it just rember the PEMDAS and you'll be fine! Good luck :3

Answer: Tony is correct</h3>
========================================================
Explanation:
There are number of ways to go about this, but let's pick on the sides marked in the diagram below (circled in red and blue). I picked on those sides specifically because they are on either side of the marked angles (A and Q).
They help form the proportion below, in which we'll show later on its a false statement.
AE/PQ = AB/QR
24/(14.5) = 18/(11.5)
24*11.5 = 14.5*18
270 = 261
We arrive at a false statement at the end, so the original proportion is false. Furthermore, it means the figures are <u>not</u> similar.
--------------
We could try the other way around and try to see if
AE/QR = AB/PQ
is true or not
Let's find out
24/(11.5) = 18/(14.5)
24*14.5 = 11.5*18
348 = 207
We see this is false as well. The gap is even bigger than before, so the first scenario was slightly close to having similar polygons. But neither case works perfectly. So that's why we don't have similar polygons and why Tony is correct. It's not enough to look at the angles only when dealing with polygons that have more than 3 sides. If we were just focused on triangles, then Jacenta would be correct.
