Lol battlefield or on a map when you're look for a particular place
35 pencils would cost $2.80,
$1.60 / 20 = $.08
Each pencil costs $0.08 each
.08 * 35 = 2.80
If 1 inch equals 20miles then 8 inches equals 20 x 8 = 160 miles.
There both types of numbers but a whole number is a number with no exponents or decimals, but decimals are like a broken un half whole number
Cross multiply
3(2x + 1) = 5(2x - 5)
expand by using distributive property
6x + 3 = 10x - 25
-4x = - 28
x = 7
