Let
x-------> the cost of the burger
y-------> the cost of the <span>sandwiches
we know that
3x+2y=27-----> equation 1
2x+y=27-11-----> 2x+y=16-----> multiply by -2-----> -4x-2y=-32--> equation 2
adds equation 1 and equation 2
</span> 3x+2y=27
-4x-2y=-32
<span>----------------
-x=27-32-----> x=5
3*5+2y=27----> 2y=27-15-----> y=6
therefore
the answer is the option
</span><span>3) The student's conclusion is correct because the solution to the system of equations 3x + 2y = 27 and 2x + y = 16 is (5, 6).</span>
To find unknown part of a whole when there are two parts, subtract the part you do know from the whole. Subtract the lbs of pears from the total lbs. 5.12 lbs total - 2.5 lbs of pears = 2.62 lbs of bananas. 2.62 lbs of bananas is your answer.(my name is actually Hannah so I couldn't resist answering.)
Answer:
Step-by-step explanation:
Slope intercept form is y = mx + b
so make the equation look like that.
-9x + 10y = -9 ... add 9x on both sides
10y = -9 + 9x
10y = 9x - 9
<span>
y = (9/10)x - (9/10)

You didn't say if the car bought is the new car or the old car so I'm assuming the car bought for $22,500 is the new car.
You divide 22,500 by 2 to get the cost of the old car. When you do this, you find out the old car costed $11,250.
the equation is 22,500/2=p
If $22,500 is the cost of the old car, then it's not my fault that the poster did not make it clear. If the previous car costed $22,500, then the previous car costed $22,500
