Answer: 25t+45m
Step-by-step explanation:
Really simple because if they traveled 25mi/h for t hours, that makes it 25t miles. They traveled 45mi/h for m hours so it's 45m. If you add them together, 25t+45m.

Answer:
the second one iy s very incorrect
The answer is To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2. The area is 20cm². ... A triangle is always half the area of a rectangle with the same height and width.
2 that's the answer lllllllllkllkllllllllllll
Since the multiplicative inverse of a fraction p/q is the fraction that swaps its numerator and denominator, i.e. q/p, we have that the inverse of 2/3 is 3/2.
So, if we multiply both sides of the equation by 3/2, we have
![\dfrac{3}{2}\cdot\dfrac{2}{3}a=16\cdot\dfrac{3}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B2%7D%5Ccdot%5Cdfrac%7B2%7D%7B3%7Da%3D16%5Ccdot%5Cdfrac%7B3%7D%7B2%7D)
3/2 and 2/3 are multiplicative inverse of each other, and by definition this means that they give 1 when multiplied:
![\dfrac{3}{2}\cdot\dfrac{2}{3}a=1\cdot a=a=16\cdot\dfrac{3}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B2%7D%5Ccdot%5Cdfrac%7B2%7D%7B3%7Da%3D1%5Ccdot%20a%3Da%3D16%5Ccdot%5Cdfrac%7B3%7D%7B2%7D)
On the right hand side, we have
![16\cdot\dfrac{3}{2}=8\cdot 3=24](https://tex.z-dn.net/?f=16%5Ccdot%5Cdfrac%7B3%7D%7B2%7D%3D8%5Ccdot%203%3D24)
And so the solution is ![a=24](https://tex.z-dn.net/?f=a%3D24)
