In this equation, is x positive, negative, or zero? x + 5 = -8

2 answers:

6 0

Now, to answer this question, we must get x on its own at either side. x + 5 is on the left hand side, so to get X in its own, we must get rid of the 5. To eliminate the 5 but keep the equation balanced, we can take 5 from both sides of the equation. So x+5-5 = -8-5. This goes to X = -13, because 5-5 is 0 and -8-5 is -13.

Therefore, x is negative.

Doña Gertrudis recolecta en promedio 75 litros de leche de cabra por día y utiliza alrededor de 5 litros para hacer un kilogramo

Nimfa-mama [501]

Answer:

825 pesos a day on average

1 dozen weight = 2.4 kg

Step-by-step explanation:

In ENGLISH:

Doña Gertrudis collects on average 75 liters of goat milk per day and uses around 5 liters to make one kilogram of cheese. The cheeses he makes weigh 200 grams each and he sells them for 132 pesos a dozen. How much money do you get per day on average from the sale of your cheeses? How many kilograms does the dozen cheeses weigh?

Solution:

75 Liters / 5 Liters = 15

15 * 1 kg = 15 kg of cheese per day

15kg in grams is 15*1000 = 15,000 grams

Each cheese block is 200 grams, so number of blocks of cheese:

15,000/200 = 75 blocks of cheese

1 dozen (12) = 132 pesos, so 1 would be:

132/12 = 11 pesos PER BLOCK

SO, 75 blocks of cheese = 75 * 11 = 825 pesos (per day on average)

Dozen cheese weight in kg,

200 grams * 12 = 2400 grams

In kg,

2400/1000 = 2.4 kg

A fourth degree polynomial with real coefficients can have -4, 8i,+4i, and as its zeros. True or false? Justify your answer.

liraira [26]

You didn't give the fourth zero, but the answer is still false. If you have a root or an imaginary number as a zero, then its conjugate is also a zero. So if 8i is a zero, then -8i must also be a zero, and if 4i is a zero, then -4i must be a zero, with those zeros and -4, the number of zeroes exceeds the number of zeroes that a fourth degree polynomial can have.

You can only draw one unique isosceles triangle that contains an angle of 55°?

blsea [12.9K]

-- If the 55° angle is one of the two equal angles, then
the third angle is 70° .

-- If the 55° angle is the third angle, then each of the two
equal angles is 62.5° .

-- For either of these cases, there are an infinite number
of possible sets of side-lengths.

The statement in the question does not hold water.
