Hi there!
I believe the answer is C. -17 - (-8), it can also be written as -17 + (8).
Hope this helped!! ☺♥
Answer:
D. It has a single solution: x=-3, y= 26.
Step-by-step explanation:
3x + y=17
Subtract 3x so it is in y=mx+b form. So now it is y= -3x +17
Now plug in
x + 2 (-3x+17) = 49
x + -6x + 34 = 49 (distribute)
-5x = 15 (combine the x terms and subtract 34 on both sides)
x = -3 (divide -5 on both sides to get x alone)
now plug in x into any other equation to get y
x + 2y = 49
-3 + 2y = 49
2y = 52 (add 3 on both sides)
y = 17 (divide 2 on both sides to get y alone)
(-3, 26)
So 2/5 are mint. that should mean if you divide 34 with 2, you will get 1/5 of the candy. SO! Divide 34 with 2 and you will get 17. The muiltiply with 5 then you will get the answer...
85 candies!!!
