Answer:
A) ∠BEC is one-half of ∠BAC
B) ∠BEC = 60°
C) ∠BDC = 120°
Step-by-step explanation:
C) arc BDC = 120°
arc BEC = 360° - 120° = 240°
∠BDC = 1/2(240°) = 120°
For this case we have the following equations:
5y = 3-2x
5y-3 = -2x
2x + 5y = 3
2x + 5y-3 = 0
The standard form of the equations is given by:
Ax + By = C
Therefore, the equation written in its standard form is:
2x + 5y = 3
Where,
A = 2
B = 5
C = 3
Answer:
The equation that is the standard form is:
2x + 5y = 3
Answer:
$4.34
Step-by-step explanation:
Given the information:
- The original price: $5
- Discount : 20%
- Tax: 8.5%
We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:
= the original price (100% - discount rate)
= 5(100% -20%)
= $4
- The tax amount she need to pay is:
= The actual price*tax rate
= $4*8.5%
= $0.34
=> the total cost of the bunch of balloons :
The actual price + tax price
= $4 + $0.34
= $4.34
Hope it will find you well.
Answer:
Step-by-step explanation:
Simplifying
f(x) = 800(0.85) * x
Multiply f * x
fx = 800(0.85) * x
Multiply 800 * 0.85
fx = 680x
Solving
fx = 680x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 680
Simplifying
f = 680
