Solve the equation: -2x+13=-7x+28

Mathematics
1 answer:
natali 33 [55]3 years ago
8 0

Answer:

x = 5

Step-by-step explanation:

-2x + 13 = -7x + 28

Subtract 13 on both sides

-2x + 13 - 13 = -7x + 28 - 13

-2x = -7x + 15

Add 7x on both sides

-2x + 7x = -7x + 7x + 15

5x = 15

Divide by 5 on both sides to isolate the variable

5x/5 = 15/5

x = 5

To 1 significant digit, how much Coumarin (in grams) would a 70 kg (154lb) student have to ingest to reach the LD50?
timofeeve [1]

Answer:

2 × 10 g

Step-by-step explanation:

The lethal dose 50 (LD50) of Coumarin is 293 mg/kg body mass. The amount of Coumarin that a 70 kg student would have to ingest to reach the LD50 is:

70 kg body mass × (293 mg/kg body mass) = 20510 mg

1 gram is equal to 1000 milligrams. The mass (in grams) corresponding to 20510 milligrams is:

20510 mg × (1 g/ 1000 mg) = 20.51 g ≈ 2 × 10 g

What is the domain of the following parabola?
yanalaym [24]

First we have to understand what the domain is. In a nutshell the domain is the set of all x values that are represented in any given graph. In this case we do not have a graph but we have the vertex. The x value is 2, therefore: x ≥ 2.


I hope this helps, Regards.
