3/4 = 4/8 (converting fractions )
4/8 + 3/8 = 9/8 cups of juice altogether
9/8 - 5/8 = 4/8 (taking away mags' amount )
4/8 is equivalent to a 1/2 so she still has 1/2 a cup of juice left.
Answer:
2.6
Step-by-step explanation:
Make this an equation. 5x-4=9. Add 4 to both sides. 5x=13. Divide both sides by 5. x=2.6. So the number is 2.6.

Answer:</h3>
y = (1/2)x - 5
<h3>
Step-by-step explanation:</h3>
Try the answers:
... -4 ≠ (1/2)·2 + 5
... -4 ≠ (1/2)·2 - 3
... -4 = (1/2)·2 - 5 . . . . . the third choice works
... -4 ≠ (1/2)·2 + 3
___
You can write the point-slope form equation and simplify.
... y -k = m(x -h) . . . . . . equation for line of slope m through point (h, k)
... y -(-4) = (1/2)(x -2) . . . filled in with your values, m=1/2, (h, k) = (2, -4)
... y = (1/2)x -1 -4 . . . . subtract 4, eliminate parentheses
... y = (1/2)x - 5 . . . . . simplified. (Matches the 3rd selection.)
You're right the towo numbers are 1.5 and 3.5 so the answer would be 10
