Answer: 2 5/15 (mixed number) or 35/15 (improper fraction)
Step-by-step explanation:
For these problems, I like to make the mixed number an improper fraction, so 7 1/3 becomes 22/3 and 5 4/5 becomes 29/5. Now, because there denominators are not the same, we can find a LCM or least common multiple to make a common denominator. 15 is the least common denominator so we can turn 22/3 to 110/15 and 29/5 to 145/15. Now we can subtract the numerators. 145-110= 35. So 35/15. It is 2 5/15 as a mixed number. Hope this helps!
the volume of a prism is v=ahh, where b is the base and h is the height. The base of the prism is a rectangle. Multiply the base by the height, and that is the volume.
Answer:
If A=10, then 2a+3=23
Step-by-step explanation:
2x10=20
20+3=23
60x+80=100x combine like terms
80=100x-60x or 40x divide to get x by itself
80/40=40x/40
20=x
