Answer:

b = 2a + c

Step-by-step explanation:

Given

a = \frac{1}{2} (b - c)

Multiply both sides by 2 to clear the fraction

2a = b - c ( add c to both sides )

2a + c = b

Which values for A and B will create infinitely many solutions for this system of equations
Ratling [72]

Answer:

A = - 2 and B = - 8

Step-by-step explanation:

A = - 2 and B = - 8 will create infinitely many solutions for this system of equations

When you add both equations together and both sides are equal then the systems have infinitely many solutions

-2x - y = 8

2x + y = -8

--------------------Add

0 = 0

Both sides are equal 0

Infinitely many solutions

Shazia sells 25x^2+5x+5 flowers in one day. If she sells the same number of flowers each day for rs 5x each , how much money wil
Mumz [18]

Answer:

Total = 625x^3 + 125x^2 + 125x

Step-by-step explanation:

Given

Flowers = 25x^2 + 5x + 5

Unit\ price = 5x

Required

The total price for 5 days

First, calculate the total for a day.

1\ day = Unit\ price * Flowers

1\ day = 5x * (25x^2 + 5x + 5)

Open bracket

1\ day = 125x^3 + 25x^2 + 25x

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

Total = 5 * [ 125x^3 + 25x^2 + 25x]

Total = 625x^3 + 125x^2 + 125x
