5x + 7 = -3 - 9

First, simplify -3 - 9 to get -12. / Your problem should look like: 5x + 7 = -12
Second, subtract 7 from both sides. / Your problem should look like: 5x = -12 - 7
Third, simplify -12 - 7 to get -19. / Your problem should look like: 5x = -19
Fourth, divide both sides by 5. / Your problem should look like: x =  -\frac{19}{5}

Answer as fraction: x = - \frac{19}{5}
Answer as decimal: x = -3.8

The probability that a lab specimen contains high levels of contamination is 0.15. A group of 4 independent samples are checked.
Lady bird [3.3K]

Answer:

0.5220

Step-by-step explanation:

Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85

The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625

This is 0.5220 to four decimal

Vlada [557]

Answer:

7x−3=7k,x=7k+3,k∈ℤ

Step-by-step explanation:

3x ≡ 2 (mod 7)

3 is a solution, since 3×3−2=7.

All solutions are 3+7ℤ

y=3x−2/7=3(x−3)+7/7=3(x−3)/7+1

7x−3=7k,x=7k+3,k∈ℤ
