Answer:
4x+15 Is the answer
Step-by-step explanation:
4(6−2x)−3(3−4x)
Distribute:
=(4)(6)+(4)(−2x)+(−3)(3)+(−3)(−4x)
=24+−8x+−9+12x
Combine Like Terms:
=24+−8x+−9+12x
=(−8x+12x)+(24+−9)
=4x+15
If you divide 8 from 140 you'll get 17.5 or 1120<span />
Answer:
A
Step-by-step explanation:
A. because the first point shows her acceleration and you can see her speed increasing when she hits the second point, so we can say that see accelerated up the ramp and after it hits the third point her speed becomes constant all the way when she reached the highway
Answer:
A. 2 1/4 + 3 2/5
B. 113/20
Step-by-step explanation: For A: All you had to do was multiply -1(-3 2/5) and that was going to make your answer positive because the negatives were going to cancel each other out.
For B: First you had to make your fractions improper fractions instead of mixed numbers. And that would make it 9/4 + 17/5. Next, since they don't have the same denominator, you would have had to find the least common multiple of 5 and 4 which is 20. So then how ever many times your denominator went in to 20, that's what you'll multiply your numerator by. 45/20 + 68/20= 113/20
