Answer:
y=5x+25
y=5(12)+25
y=85
Step-by-step explanation:
115%(15,800)= $18,170. <--- markup price
$15,800+$18,170= $33,970 total price
That is 115% x $15,800 = $18,170 markup price
Then add the original price to the markup price
That is $15,800 + $18,170 = $33,970
8x - 12y
4(2x-3y)
Distribute/multiply the 4 to everything in the parentheses
4 * 2x = 8x 4 * -3y = -12y
2000cm²
find the other side using pythagorean theorem
50²=30²+x²
x=40
Area = 40 * 50 = 2000cm²
