Hi!
3.28$ = 328 cents
8 1/5 ounces = 41/5 ounces
We will find the unit cost, cents per ounce, using proportions, like this:
328 cents for 41/5 ounces
x cents for 1 ounce
________________________
x = (328*1)/(41/5)
x = 328/(41/5)
x = (328*5)/41
x = 1640/41
x = 40
Unit cost = 40 cents per ounce.
Hope this helps!
Since neither of the bracketed expressions is preceded by a minus sign, and neither one has a multiplier outside of it, all of the parentheses can simply be removed.
<span>(3x - 5) + (3x + 6)
3x - 5 + 3x + 6
Combine the 'x'-terms: 3x + 3x = 6x
Combine the numbers: -5 + 6 = 1
The expression is equivalent to . . . . . <u>6x + 1</u>

The first one is 810

The area of the drawing of the park is 64 cm²;
Scale: Square park to Drawing = 5m:1cm
= 5m:0.01m;
Therefore; Square Park Area = 1600m²;
Drawing Area = 1600 ×(0.01/5)²
= 0.0064m² = 64 cm²
