Answer: x ≤ 1

reason:

first, multiply 4x and 4 by -2/3, which leaves you with the equation 2x ≤ -8/3x + 8/3
then, you add 8/3x to both sides, making it 4 2/3x ≤ 8/3
divide both sides by 4 2/3 and you get x ≤ 1

Answer:

x ≤ 4/7

Step-by-step explanation:

Simplify the given 2x ≤ -2/3 (4x + 4) by multiplying both sides by (3/2):

(3/2)(2x) ≤ (3/2)(-2/3)(4x + 4)

We get 3x ≤ -4x - 4

Solve for x by combining like terms.  Add 4x to both sides, obtaining

7x ≤ 4

and so the solution is the set

x ≤ 4/7

-30=5(x+1)−30=5(x+1) proszę szybką odpowiedź :)
den301095 [7]

Answer:

x = -7

Step-by-step explanation:

The given equation is :

-30=5(x+1)

We need to solve the equation.

Use associative property on RHS.

-30 = 5x+5

Subtract 5 from both the sides.

-30-5 = 5x+5-5

-35 = 5x

x = -7

Hence, the value of x is -7.

Put this into your own words and I will mark brainliest, need ASAP!!!!!
Arada [10]

Answer:
Part A: 55

Step-by-step explanation:

The measure of angle x is 55 I found this by finding angle BPR.

Then I found that we start with 180 - 120 and that equals 60. That means that angle BPR is 60 degrees. Then we need to do 65 + 60 + x =180. To find the x we do 65 + 60 and that gives us 125. After simplifying that from simple algebra we get x=55
