So let T be the max and min temperature, and let x be the given temperature in °F.
T = x+-12
So for this case the Tmax will be 40°F using the equation above.
And Tmin being 16°F
X=5 and y =2.
Here's how you do it.
Multiply the first equation by -3, and the second one by 1.
add the equations to eliminate x.
then solve for y by dividing both sides by -5, which gives us 2.
to solve for x subsitute 2 in for y.
<u>Answer:</u>
$14
<u>Step-by-step explanation:</u>
Assuming the cost of folder to be 
, then the cost of notebook will be 
and the cost of set of pencils will be 
.
Cost of the folder = $2
Cost of notebook = 4 × 2 = $8
Cost of pencil = 2 × 2 = $4
Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14
Answer:
Infinitely Many Solutions.
Step-by-step explanation:
x+2y=0
6y=-3x
y=-3/6x
y=-1/2x
x+2(-1/2x)=0
x-2/2x=0
x-x=0
0=0
infinitely many solutions
