Answer:
x = 10.25
y = 6.7
Step-by-step explanation:
X = 8 - (-2.25) = 10.25
Y = 6 - 4.2 - (-4.9) = 6.7
The answer is 10
10-1=9
9*8=72
( 5/3 + 2 2/5 ) ÷ ( 1 3/4 ) =
( 5×5/3×5 + 2 2×3/5×3 ) ÷ ( 4/4 + 3/4 ) =
( 25/15 + 2 6/15 ) ÷ ( 7/4 ) =
(25/15 + 30/15 + 6/15 ) ÷ ( 7/4 ) =
( 25 + 30 + 6 / 15 ) ÷ ( 7/4 ) =
( 61/15 ) ÷ ( 7/4 ) =
61/15 <em>×</em><em> </em><em>4</em><em>/</em><em>7</em><em> </em> =
61 × 4 / 15 × 7 =
244 / 105
You would want to make it into an addition problem that looks like this:
