The sum of two numbers and their difference is 30.
Step-by-step explanation:
x+y=5
3x-2y+5=0
3x-2y= -5
x+y=5...... equation 1
3x-2y= -5....... equation 2
there fore make x the subject of the formula in equation 1
x=5-y.. equation 3
substitute equation three in equation 2
3(5-y)-2y=-5
15y-3y-2y=-5
10y=-5
divide both sides by 10
y=-5/10
y=-½
substitute y into equation 1
x+(-½)=5
x=5+½
x=5½
x=5½,y= -½
M =0 if you put it in y= and hit 2nd graph and go down to the 0 there is a 1 with means m =0 (ti-84+ caculater)

Question:
How many tons are equal to 36,000 pounds?
Answer:
<h2><u><em>
18 tons </em></u></h2>
Step-by-step explanation:
<em>To convert a pound measurement to a ton measurement, divide the weight by the conversion ratio.</em>
<em />
<em>Since one ton is equal to 2,000 pounds, you can use this simple formula to convert:</em>
<em />
<em>tons = pounds ÷ 2,000</em>
<em>The weight in tons is equal to the pounds divided by 2,000.</em>
<em />
<em>And you could multiply 2,000 by 18 and get the answer 36,000</em>
<em />
<em />
