Answer:
$8.00
Step-by-step explanation:
For every pound shipped, $0.40 is charged. This can be represented by the mathematical equation: y=0.4x, where x is the pounds to ship and y is the total cost. If we plug in 20 as x to find what the total cost would be, we would have the equation, y=0.4*20, and y would equal 8, meaning that the total cost is $8.00.

Answer:
x = 25
Step-by-step explanation:
Equiangular triangle is also equilateral triangle.
This means their sides are of equal length.
So, AB = BC = AC
Consider AB = BC
3x - 5 = 2x + 20
3x - 2x = 20 + 5
x = 25
Check:
Length of AB = 3x - 5 = 3(25) - 5 = 75 - 5 = 70
Length of BC = 2x + 20 = 2(25) + 20 = 50 + 20 = 70
Length of AC = 4x - 30 = 4(25) - 30 = 100 - 30 = 70
