Answer:
The answer to your question is below
Step-by-step explanation:
Equation 1
$sweatshirt = 2 pair of shorts
<u> w = 2h</u>
Equation 2
$t-shirt = $pair of shorts - $4
<u> t = h - 4</u>
Equation 3
Total cost = 3 sweatshirts + 2 pairs of shorts + 5 t-shirts
<u>Total cost = 3w + 2h + 5t = 136 </u>

Remember that x =r cos theta and y = r sin theta. Thus,
x + y = r (cos theta + sin theta) = 4, or
r (cos theta + sin theta) = 4, or
4
r = -------------------------------
cos theta + sin theta
3x + 2y = 6....solution (0,3)
-5x + y = -10...solution (1,-5)
x - 4y = 8...solution (4,-1)
-6x - 5y = 30...solution (0,-6)
Answer:
$88.50
Step-by-step explanation:
you start by turning the decimal to a fraction by moving the decimal dot 2 places to the left so now you have 0.18
then multiply 0.18 * 75 to get 13.5
then add 15.5 + 75 to get the total meal price which is 88.5
