All you have to do is the price multiplied by the amount of kg. BUT make sure that they are both in the same units, in this case they are both in kilograms. So you do 7.25x20=$145
These are the equations given:
31=B+J
B=2J+4
So you substitute B=2J+4 into 31=B+J
31=2J+4+J
Solve
31-4=3J+4-4
27=3J
27/3=3J/3
9=J

Answer:
C. 120 deg
Step-by-step explanation:
All sides of a rhombus are congruent.
That means that triangle ADC is an isosceles triangle with AD = CD, so angles DAE and DCE are congruent.
m<DAE + m<DCE + m<ADC = 180
30 + 30 + m<ADC = 180
m<ADC = 120
Opposite angles of a rhombus are congruent, so
m<ABC = m<ADC = 120
Use the Pythagoras Theorem:-
5^2 = x^2 + 3^2
x^2 = 5^2 - 3^2 = 16
x = sqrt 16 =4 feet Answer
