Step-by-step explanation:
12 x 9.95 = 119.4 dollars
119.4+5.00=124.4
The total cost is $124.40.
C = pi * d
Plug in what we know:
C = 3.14 * 26
Multiply:
C = 81.64
Answer:
y= - 3/4x + 13/2(8.5,0)(0,6.5)
rounded (9,0)(0,7)
{-2x-5y=13
<u>{2x-5y=17 </u>(+)
<em /> -2x+2x-5y-5y=13+17
-10y=30 /:(-10)
y=-3
2x-5y=17
2x-5*(-3)=17
2x+15=17
2x=2
x=1
<em>Solution: (1; -3)</em>
2 and 14/15
Because the first step of subtraction is common denominators
