Answer:

Step-by-step explanation:

Given that

(3x) is raised to power 5

(3x)^5

Then,

Using indices

(AB)ⁿ = Aⁿ•Bⁿ

Then,

(3x)^5= 3^5•x^5

Then, 3^5 means=3×3×3×3×3=243

So,

(3x)^5= 243x^5

Which expressions are equivalent to -2(5x-1)+7(5x-1)-3(-5x+1)

blondinia [14]

Answer:

x=1/5

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's go back to the given question

-2(5x-1)+7(5x-1)-3(-5x+1)

We can actually equate the equation to zero

Let's solve

-10x+2+35x-7+15x-3=0

Let's collect like terms

-10x+35x+15x=-2+7+3

40x=8

Let's make x the subject of formula by dividing both sides by 40

x=1/5

So the final answer is 1/5

Find all x ∈ Z satisfying each of the following equations.3x = 2 (mod 7)

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
