3x-7>2
add 7 to both sides: 3x>9
divide both sides by 3: x>9

Basically you just do the opposite of whatever is being done to x. So, first, you would ADD 7 to both sides to cancel it out from the side where x is. Remember: the goal is to isolate x. So, add 7, and you have:

3x - 7 + 7  > 2 + 7

Note that -7 + 7 = 0. So, we have successfully cancelled out that term. Then, just do the rest of addition:

3x > 9

Then, the the 3 is being multiplied to x, and you want to get rid of it on that side. So, you do the opposite of multiplication, which is division. You can divide the inequality by 3 on both sides to get:

3x / 3 = 9 / 3 or:
x = 3. 

Note that 3x / 3 is equal to 1x or just x. Here we want that 1 to not get rid of x, because we want to find the value of x.

Remember: isolation of x is what you want. If you need more help/have questions, feel free to tell me.

PLEASE HELP ME ASAP ILL MARK BRIANLIEST!!!!!!!!! ANSWER THE QUESTIONS AND DO THE STEPS TOO PLEASEE
Anon25 [30]

Answer:

1). t ≥ -\frac{3}{2}

2). k ≥ \frac{16}{3}

3). y < -\frac{1}{2}

4). b > \frac{250}{9}

5). w ≤ 0

Step-by-step explanation:

1). 14(\frac{1}{2}-t)\leq 28

   \frac{14}{14}(\frac{1}{2}-t)\leq \frac{28}{14}

   \frac{1}{2}-t\leq 2

   -t\leq 2-\frac{1}{2}

   -t\leq \frac{3}{2}

   t ≥ -\frac{3}{2}

2). 15k + 11 ≤ 18k - 5

   15k - 18k ≤ -5 - 11

   -3k ≤ - 16

   3k ≥ 16

     k ≥ \frac{16}{3}

3). 44y > 11 + 88y - 22y

    44y > 11 + 66y

    44y - 66y > 11

    -22y > 11

    22y < -11

    \frac{22y}{22}

    y < -\frac{1}{2}

4). \frac{7}{9}(b - 27) > \frac{49}{81}

    \frac{7}{9}(b - 27)\times \frac{9}{7} > \frac{49}{81}\times \frac{9}{7}

     (b - 27) > \frac{7}{9}

     b > \frac{7}{9}+27

    b > \frac{250}{9}

5). 11w - 8w ≥ 14w

    3w - 14w ≥ 0

    -11w ≥ 0

    w ≤ 0

Angle D has what measurement according to the protractor?
Aliun [14]

Answer:

B. 90^o

Step-by-step explanation:

We have been given a protractor and we are asked to find the measure of angle D.

We can see from our given protractor that the measure of angle D is 90 degrees as the ray OD crosses our protractor at 90 degrees.

Therefore, the measure of angle D is 90 degrees and option B is the correct choice.
