Pretty sure its 3.2.......
13 meters is around 512 in
to get that you do 13x39.37
Step one: Subtract $15 - $5.50 = $9.50
<span>Step two: divide $9.50 ÷ $15 = .633 (rounded) </span>
<span>Step three: Multiply .633 * 100 to change it to a percent. It becomes 63.3% (rounded) </span>
<span>The decrease is 63.33% </span>
<span>Proof: $15 * .63333 = $9.50 </span>
<span>Subtract $15 - $9.50 = $5.50
does this help??</span>
It's A, you have to get the total cost of the products before you can attempt to find the difference
Answer:x=2
y=6
Step-by-step explanation:
-7*x+4*y=10
║minus
-5*x+3*y=8
----------------
-2*x+y=2
y=2+2*x
-------------
-5*x+3*(2+2*x)=8
-5*x+6+6x=8
x=8-6
x=2
-------------------------
-7*2+4*y=10
4*y=10+14
4*y=24
y=24/4
y=6
