the answer for a = 1
Simplify 19/4a to 19a/4
61/28 + a = 19a/4 - 11/7
Multiply both sides by 4
61/7 + 4a = 19a - 44/7
Subtract 4a from both sides
61/7 = 19a - 44/7 - 4a
Simplify 19a - 44/7 - 4a to 15a - 44/7
61/7 = 15a - 44/7
Add 44/7 to both sides
61/7 + 44/7 = 15a
Simplify 61/7 + 44/7 to 15
15 = 15a
Divide both sides by 15
1 = a
Switch sides
<u>a = 1</u>

Suppose y varies inversely with x and that y=2 when x=8 What is an equation for this inverse variation?
B. y= 2/8x
13:12
52% 2400 = 1248
48% 2400 = 1152
Reduce to 13/12 = 13:12
Hope this helps.
