Answer:
you have simply written 2 matrices in the picture. Tell me which operation do you want to apply on these rectangular matrices
Step-by-step explanation:
I'm going with C. scalene triangle
I think X is 2. But I am not sure, cuz I don’t know what you teacher is really asking you to do.
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>
First, you divide the fraction, and then you multiply it by 100.
So you get:
So, 5/16 is 31.25%
Hope this Helps! :)
