Answer: the selling price of the television at store B is $1360
Step-by-step explanation:
Assuming the selling price of the television at store B is represented by $B. Store A is selling the television for $800, which is $120 more than half the cost of the television at store B. The equation representing this situation is expressed as
800 = B/2 + 120
Multiplying the left hand side and the right hand side of the equation by 2, it becomes
1600 = B + 240
B = 1600 - 240
B = $1360
Answer:
x = - 3, x = 2
Step-by-step explanation:
Since x = 1 is a zero then (x - 1) is a factor of the polynomial
dividing x³ - 7x + 6 ÷ (x - 1)
= (x - 1)(x² + x - 6)
= (x - 1)(x + 3)(x - 2)
equating (x + 3)(x - 2) = 0 gives the other zeros
equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Answer:
34 degrees
Step-by-step explanation:
Every quadrilateral has 4 interior angles with the sum of 360 degrees.
In this case, a right trapezoid, with 2 of its angles already known: 90 & 90
The third angle is given to us: 146
Set up equation:
90 + 90 + 146 + w = 360
326 + w = 360
w = 34 degress
