If 5x - 2 = -12. then x =

Mathematics

Yuliya22 [10]3 years ago
8 0

Answer:

x = -2

Step-by-step explanation:

First let's solve the given equation.

5x - 2 = -12

Combine the constants by adding 2 to both sides.

5x = -10

Isolate x by dividing both sides by 5.

x = -2

This is your answer.

Check your answer by plugging x = -2 back into the equation.

5x - 2 = -12

5(-2) - 2 = -12

-10 - 2 = -12

-12 = -12

Your answer is correct.

Hope this helps!

Which one of the following measurement represents the longest distance 5m, 10cm, 50mm, 1km
ElenaW [278]

First you need to convert them to one common measurement... I'll use cm for the measurement.

  • 1m = 100 cm
  • 10 cm = 10 cm
  • 50 mm = 0.1 cm
  • 1 km = 100000 cm

Using this info to convert gives

  • 500 cm
  • 10 cm
  • 5 cm
  • 100000 cm

The smallest is 50 mm which is equal to 5 cm

Adalimumab (Humira), a recombinant human monoclonal antibody, is available in a prefilled syringe containing 40 mg/0.8 mL. Calcu
Neporo4naja [7]

Answer:

The concentration of the drug is 50mg/mL.

Step-by-step explanation:

This problem can be solved by a rule of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

In this problem, as the number of mg increases, so does the number of mL. It means the we have a direct rule of three.

Tha problem states that the antibody is available in a prefilled syringe containing 40 mg/0.8 mL. Calculate the concentration of drug on a mg/mL basis.

The problem wants to know how many mg are there in a mL of the drug.

40mg - 0.8mL

x mg - 1 mL

0.8x = 40

x = \frac{40}{0.8}

x = 50mg.

The concentration of the drug is 50mg/mL.

Which of these values of x is NOT a solution of the equation tanx= 1?
Kobotan [32]

The tangent ratio is an illustration of the trigonometry identity

The value of x that is not a solution of tan(x) = 1 is 3\pi/4

<h3>How to determine the value that is not a solution</h3>

The trigonometry identity is given as:

tan(x) = 1

Next, we test the x values using a calculator.

When x = -7\pi/4, we have:

tan(-7\pi/4) = 1

When x = 3\pi/4, we have:

tan(3\pi/4) = -1

When x = 5\pi/4, we have:

tan(5\pi/4) = 1

When x = \pi/4, we have:

tan(\pi/4) = 1

Hence, the value of x that is not a solution of tan(x) = 1 is 3\pi/4
