That would be 8.5
Have a nice day!

Group is the answer I think
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.

I dont think kris made a mistake
Explanation: lets try solving a fraction using kris’s method. Fraction:120/50
common multiple for both numbers:10
we divide 120 by 10 and 50 by 10= 12/5. We cant find and common multiples so thats the final answer.(using kris’s method)
if u try using a calculator u can see that the answer is 12/5 or 2.4. This means that kris’s method is not wrong
In order to calculate the y-intercept of the line described by the equation
y = 5x -22, we have to put x = 0. This is because y-intercept represents the point at which the straight line crosses the y-axis.
If we put x = 0, then 5x becomes 5 x 0 = 0
Therefore, the equation becomes, y = 0 - 22
For this reason, the y-intercept of the line is y = -22.
