Step-by-step explanation:
Equations:
Quantity:: d = n + 3
Value::: 10n + 5d = 615 cents
-------------------------------------------
Modify::
d - n = 3
d + 2n = 123
--------------------------------------------
Subtract and solve for "n"::
3n = 120
n = 40 (# of nickels)
d = n+3 = 43 (# of dimes)
Answer:
Firstly find the area of the square and then the area of the two triangles and then plus it. That's what I think I tried
1400
Not sure which ratio you need, but 6/9 = 2/3
1.5xsalmon=swordfish
$39 = 2lb salmon and 3lb swordfish
1lb salmon=$6 6+6 = 12
1lb swordfish=$9 9+9+9 = 27
12+27 = 39
Answer: Center: (-7,6)
Radius: 4
It is located in the 3rd quadrant since x = -3 and y = -4.
