<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>
Answer:
Step-by-step explanation:
LOGb(x)=y
4^5=1024
= log(4)1024=5
Answer:
you times that by 7 I think
