What is x in this equation- 3/2x-7=-11
Sunny_sXe [5.5K]

3/2x-7=-11


We move all terms to the left:


3/2x-7-(-11)=0



Domain of the equation: 2x!=0


x!=0/2


x!=0


x∈R



We add all the numbers together, and all the variables


3/2x+4=0


We multiply all the terms by the denominator



4*2x+3=0


Wy multiply elements


8x+3=0


We move all terms containing x to the left, all other terms to the right


8x=-3


x=-3/8


x=-3/8

Hi, can you please help me answer this direct proportion question?
Oksanka [162]

Answer:

X = 100

Step-by-step explanation:

  • In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
  • This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
  1. Multiply the left by k, so y = \frac{k}{\sqrt{x} }
  2. we know that y= 5, for x = 36, so sub this in the equation
  3. 5 = \frac{k}{\sqrt{36} }
  4. simplify5 = \frac{k}{6 }
  5. re-arrange for k, <u>k = 5*6 = 30</u>
  6. now we know k, we can create the real equation, y = \frac{30}{\sqrt{x} }
  7. sub in 3 as y
  8. 3 = \frac{30}{\sqrt{x} }
  9. <u>x = 100</u>

Can someone please help me!!
Vladimir [108]

Answer:

#18)  <em>m</em>∠B = 107°

#19) <em>m</em>∠B = 17°

Step-by-step explanation:

*Supplementary angles are angles who's measures equal 180°

*Complementary angles are angles who's measures equal 90°

#18) If ∠A is 73°, then we must subtract 73 from 180.

180 - 73 = 107

This means that <em>m</em>∠B = 107°.

#19) If ∠A is 73°, then we must subtract 73 from 90.

90 - 73 = 17

This means that <em>m</em>∠B = 17°.

Find the perimeter and area of the figure. Round to the nearest tenth if necessary. 33.7 mm; 108 mm2 33.7 mm; 54 mm2 30.7 mm; 50
Deffense [45]

Answer:

Perimeter: 33.7 mm

Area: 54 mm

Step-by-step explanation:

If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A = \frac{1}{2} x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.
