<span>Equation:
silver + silver = silver
0.45x + 0.60(40-x) = 0.48*40
----------------
45x + 60*40 - 60x = 48*40
--------
-15x = -12*40
x = (4/5)40
x = 32 lbs (amt of 45% slloy needed)
40-x = 8 lbs (amt of 60% alloy needed)</span>
The answer would be 893.4
Answer:
x = -17.5
Step-by-step explanation:
7x-5= -35
-35/2 = -17.5
[ 1 - 4]
= 1- 4
= 1 + - 4
= - 3
+ [ - 2 6]
= - 12
[ 3 5][ - 2 4]
(3)(5)(( - 2)(4))
= 15(( - 2)(4))
= (15)( - 8 )
= - 120
Its 8 divided by 3 which equals 2.6
