The answer to the question is 15x+30-64
You have to find a common denominator for both fractions. I chose the denominator to be 10, so the 1/2 will become 5/10, and 1/5 will become 2/10.
Subtract 5/10 from 2/10. You will get -3/10.
Answer: -3/10
You can check your answer by solving 1/2-3/10=1/5 to see if it is true. (It is:)
Answer:
400 x 0.3 = 120 miles
120 miles would be your answer
Step-by-step explanation:
Let x be the width so the length will be 2x-4 . The perimeter can be found by the equation x+x+(2x-4)+(2x-4)=58. Notice I repeated the length and the width twice because you know there are two lengths and two widths in a rectangle, so continue solving by combining like terms 6x-8=58 the add 8 to both sides 6x=66 then divide both sides by 6 to obtain x=11, that's the width but they are asking you for the length so we said the length could be found by the equation 2x-4, now plug in the 11, 2(11)-4 and solve 22-4 equals 18cm which is the length.
2p^2 + 30p + 108 2(p + 6)(p + 9)
----------------------- = -------------------- = 2(p + 9) / (p - 1)
p^2 + 5p - 6 (p + 6)(p - 1)
Its the first choice
