Evaluate b-(-1/8)+c where b=2 and c=-7/4​

Mathematics
1 answer:
tatiyna3 years ago

Answer:

3/8

Step-by-step explanation:

Evaluate b - -1/8 + c where b = 2 and c = -7/4:

b - (-1)/8 + c = 2 - (-1)/8 - 7/4

Put 2 + 1/8 - 7/4 over the common denominator 8. 2 + 1/8 - 7/4 = (8×2)/8 + 1/8 + (2 (-7))/8:

(8×2)/8 + 1/8 - (7×2)/8

8×2 = 16:

16/8 + 1/8 - (7×2)/8

2 (-7) = -14:

16/8 + 1/8 + (-14)/8

16/8 + 1/8 - 14/8 = (16 + 1 - 14)/8:

(16 + 1 - 14)/8

16 + 1 = 17:

(17 - 14)/8

The sum of four consecutive integers is −46. What is the smallest of these integers?
Gwar [14]

Answer:The integers are -13, -12 and -11.

Step-by-step explanation:

Let the four numbers be n, n+1, n +2, and n+3

Therefore (n )+ (n+1 )+(n+2) + (n +3) = -46

4n + (1 +2+3) = -46

4n + 6= -46

Subtract 6 from both sides to get the value of n

4n +6 - 6= -46 -6

4n = -52

Divide both sides by 4

n = -52/4

n = -13

Therefore, n + 1 = -13 + 1= -12

n + 2= -13 + 2 = -11

The integers are -13, -12 and -11.

I hope this helps, please mark as brainliest.

C(x) = 0.6x+ 15,000 and R(x) = 1.25x where x is the number of units produced.
Arisa [49]

The profit function is the difference between the cost and revenue functions

The profit function is P(x) = 0.65x - 15000

<h3>How to calculate the profit function</h3>

The functions are given as:

  • Cost function: C(x) =0.6x + 15000
  • Revenue function: R(x) =1.25x

The profit function is then calculated as:

P(x) =R(x)-C(x)

So, we have:

P(x) = 1.25x - 0.6x - 15000

Evaluate the differences

P(x) = 0.65x - 15000

Hence, the profit function is P(x) = 0.65x - 15000
