<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: 8
Step-by-step explanation:
4+15+11+5+7+10= 50 cm
10cm was the missing one
Answer:
C. 6
Step-by-step explanation:
Recall that inverse variation is given by:

Where <em>k</em> is the constant of variation.
We know that <em>y</em> = 48 when <em>x</em> = 3. Substitute:

Solve for <em>k: </em>
<em />
<em />
<em />
Hence, our equation is:

We want to find <em>x</em> when <em>y</em> = 24. Substitute:

Cross-multiply:

Divide both sides by 24. Hence:

Our answer is C.
6:13 =83
6+13=19
1 part=83÷19
=4.37
6×4.4=26.4
13×4.4=57.2
26.4:57.2
p.s I got how much money only...
sorry
