Answer: (8,4)
Explanation:
First start by isolating the x in -2x+9y=11 to get x=4.5y-5.5.
Substitute the x in -5x+2y=-34 for 4.5y-5.5.
Solve for y, get 3.
Substitute the y in -2x+9y=11 for 3, solve for x and get 8.

Answer: The basketball will sell for $21
.
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the cost of the basketball (10) by the percent markup in decimal form (divided by 100).
Mathematically speaking:
10 x (110/100) = $11
Now, we have to add the markup amount (11) to the cost (10) to obtain the selling price:
10 +11 = $21
The basketball will sell for $21
.
