<span> An </span>equation<span> is a mathematical statement that shows the equal value of two expressions while an </span>inequality is a mathematical statement that shows that an expression is lesser than or more than the other. "<span>An 18-wheel truck stops at a weigh station before passing over a bridge. The weight limit on the bridge is 65,000 pounds. The cab (front) of the truck weighs 20,000 pounds, and the trailer (back) of the truck weighs 12,000 pounds when empty. In pounds, how much cargo can the truck carry and still be allowed to cross the bridge?" does this help?</span>
Step-by-step explanation:
the common denominator for these two is 45, as you have to times 5 by 9 to get this you will have to times 3 by 9 aswell so that fraction would be 27/45.
as you have to times 9 by 5 to get 45 you will have to times 5 by 5 which is 25 so that fraction would be 25/45
3/5=27/45 5/9=25/45
27 is bigger than 25
There are no equations there. Only two functions of x.
<span>A) 12x + 15y = 34
</span><span>
</span><span>B) -6x + 5y = 3 Multiplying B) by -3
</span>
B) 18x -15y = -9 Then adding this to A) equals
30x = 25
x =
<span>
<span>
<span>
0.8333333333...
</span></span></span>
<span>A) 12x + 15y = 34
</span>
12 * <span>
<span>
<span>
0.8333333333... + 15y = 34
</span></span></span><span><span><span>
</span></span></span><span><span><span /></span></span>10 + 15y = 34
15y = 24
y = 1.6

Answer:
yeah I'm sorry I dont understand this one either hun
