Answer:
$84
Step-by-step explanation:
720x30=21600
21600/100=216
216=markdown (as a number instead of a percentage)
Now subtract that like this
720-216=504
504= sale price
Then do this
504-420=84
<em><u>Therefore it is $84</u></em>

Answer:
The plumber worked for 1.5 hours
Step-by-step explanation:
y = 130 + 56x
Substitute 214 for y in the equation
214 = 130 + 56x
-130 -130 Subtract 130 from both sides
84 = 56x Divide both sides by 56
1.5 = x

Answer:
w + 2.56 ≥ 10.24
Step-by-step explanation:
The least w + 2.56 could be is 10.24 which means that w + 2.56 could be more than 10.24
Problem One
Test it.
a^2 + b^2 = c^2
a = 8
b = 12 What will c calculate to be.
8^2 + 12^12 = c^2
c^2 = 64 + 144
c^2 = 208
If 18 is to be the hypotenuse of the triangle c^ must equal 324.
208 is nowhere's near that amount.
Mario is right.
Question Two
The only way Hank will be right is if 26 is the hypotenuse. If that is so, the third side is 24. This is how you do it.
a^2 + b^2 = c^2
c = 26
a = 10
10^2 + b^2 = 26^2
100 + b^2 = 676 Subtract 100
b^2 = 676 - 100
b^2 = 576
b = sqrt(576)
b = 24
If 26 is not the hypotenuse, the right triangle cannot be drawn.
