Set up your two equations:
<span>9x+7y=53 </span>
<span>3x+5y=25 </span>
<span>X=cost per pound of jelly bean </span>
<span>Y=cost per pound of trail mix </span>
<span>Multiply the second equation by (-3): </span>
<span>-9x-15y=-75 </span>
<span>+ 9x+7y=53 <---- copy first equation and add them </span>
<span>—————— </span>
<span>0x-8y=-22 </span>
<span>Then solve for y: </span>
<span>Y=2.76 this is your cost per pound of trail mix. </span>
<span>Then plug y back in to one of the original equations and solve for x: </span>
<span>3x+7(2.75)=25 </span>
<span>X=3.75 this is you cost per pound of jelly beans</span>
Answer:
(-3, 3)
Step-by-step explanation:
Answer:
watt is the standard unit of power in metric units
Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68 
43, we have to determine the partial products in this.
Now, 
Expanding this, we get
= 
= 2400 + 180 + 320 + 24
= 2924
Hence, 
and 
are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
