Answer:
x = 7, y = -5
Step-by-step explanation:
<u><em>Given~:</em></u>
<em>Solve the system below using elimination</em>
<em>{5x+9y= -10}</em>
<em>{7x+10y= -1}</em>
<u><em>Solve:</em></u>
<u><em></em></u>
Isolate x ( 5x + 9y = -10 ) : 
Substitute:
Isolate y : 
Substitute: 
Hence, 
Therefore, the solution for are:

Answer:
2880
Step-by-step explanation:
The base is made up of two triangles and a square, if that makes sense. Finding the area of a triangle is (base x height)/2.
The base of the tiny triangle is 4 because there is 8 inches extra to the 10 inch square. <u>10 x 4 = 40.</u>
Now we have a 10 by 10 square: <u>10 x 10 = 100. </u>
So, the area of the trapezoid is 140. There are two trapezoids in this prism, so both bases are 280.
The surface area of the sides are solved by <u>12 x 50 = 600. </u>Together, the sides equal 1200.
The top is solved by <u>10 x 50 = 500.</u>
The bottom is solved by <u>18 x 50 = 900.</u>
Add them all together: 280 + 1200 + 500 + 900 = 2,880
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50
