2/3 + 3/5 - 3/5 - 5/2 ayud

the answer of the simplification is -1

Step-by-step explanation:

2/3 + 3/5 - 3/5 - 5/2

= 2/3 - 5/2 (same value but the sign are opposite, so we can eliminate +3/5 and -3/5)

now lcm (3 , 2) = 6

2/3 = (2 X 2)/( 3 X 2) = 4/6

5/2 = (5 X 3)/(2 X 3) = 15/6

now 4/6- 15/6

= (4 - 15)/6

=-11 / 6 ( changing into mixed fraction)

=-1

-1  1/2 (its a simplified mixed number) or if you want it as simplified improper fraction, -3/2

Step-by-step explanation:

I know that +3/5 and -3/5 are exact opposites. I cancel that out so I'm left with 2/3-5/2. I find the least common multiple (LCM) which is 6. I get the denominator to 6 by multiplying 2/3 * 2/2 (3*2=6). I get 4/6. Now I multiply 5/2*3/3 (2*3=6) which is 15/6. Now the denominators are the same so we can go ahead and solve. 4/6-15/6. 4-15=-9/6. 9/6 can be simplified to -3/2 which is also the same as -1 1/2.  

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

heyyy
