Answer:
3/8
Step-by-step explanation:
4/8 = 1/2
Subtract the amount her son ate (1/2 or 4/8) from the total amount and you get 3/8.
No, the students answer is decently far off the correct answer would be 1 7/10 pounds because, to add fractions you first need to find a common denominator that both of the numbers go into for example for this one 10 is a common denominator because 5 goes into 10 twice and 10 goes into 10 once so we multiply 4/5 by 2 because it take twice the amount of 5 to get to 10 and what we do to one side we must replicate on the other side as well. Like so,
4/5*2=8/10 now all the we have to do is take 8/10+9/10=17/10 and simplifying that down you get 1 7/10 because 10 goes into 17/10 one time with 7 left over and because 7 is prime that answer can not be simplified down any more.

The answer would be A. -0.86 because if you plug in -0.86 for r then add -0.86 and 0.27 then you would get the correct answer which would be -0.58. :)
Answer:
LM+MN=LN
3x-5+x+7=17
4x=17+5-7
4x=15
x=15/4=3.75
LM= 3x-5=3*3.75-5=6.25
