Step-by-step explanation:
This is the concept of algebra, let the original length of the hexagon be x, after the dilation the length became x×7/5=7/5x
the perimeter of the original figure is:
6*x=6x
The perimeter of the enlarged on is:
6*7/5x=8.4x
therefore the perimeter of the new compared to the old will be:
8.4x/6x
=1.4
the new perimeter is 1.4 times the old perimeter

x (.60) + 60 (.15) = (x+60) .50
distribute
.60x +9 = .5x +30
subtract .5x from each side
.1x +9 = 30
subtract 9 from each side
.1x = 21
divide by .1
x = 210
You will need 210 gallons of 60% antifreeze

Step-by-step explanation:
Step 1. Calculate the <em>pounds of broccoli</em>.
Start with what you know: you want 32 oz of broccoli.
You know that 1 lb = 16 oz. Calculate the weight in pounds
Wt = 32 × 1/16
Wt = 2 lb
===============
Step 2. Calculate the <em>cost of the broccoli</em>.
$1.50 = 1 lb Calculate the cost
Cost = 2 × 1.50/1
Cost = $3.00
