Answer: $50 + $2.49x = $67.43
Step-by-step explanation:
Let the case of water bought be represented by x.
We are informed that Sam's Club has a special that charges $2.49 per case of water and that Vinny wants to pay that price, but needs to purchase a membership first, which costs $50 and that Vinny eventually spent $67.43.
The equation that represents the number of cases of water that Vinny bought at Sam's club will be:
$50 + $2.49x = $67.43

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
3x + 3x + 10 + 2x + 10 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 8x + 20 = 180
- Isolate <em>x</em> term: 8x = 160
- Isolate <em>x</em>: x = 20
<span>perimeter of a rectangular rug is 30 yd
P= L+L+W+W
</span><span>P= 9+9+W+W
P= 18 + 2W
</span><span>18 + 2W = 30
2W = 30-18
</span><span>W= 12/2 = 6
A= L x W

Answer:
The above system of equation have NO INTERSECTION POINT.
Step-by-step explanation:
Here, the givens system of equation are:
-3 x + 3 y = 4
and y = x + 3
Now, for the intersection of the equations:
Put y = x + 3 in the given first equation:
-3 x + 3 y = 4 ⇒ -3x + 3 (x+ 3) = 4
or, - 3x + 3x + 9 = 4
⇒ 9 = 4 which gives A CONTRADICTION as 9 ≠ 4
Hence, the above system of equation have NO INTERSECTION POINT.
