Answer:

x=17

Step-by-step explanation:

<em>Distributive property: A(B+C)=AB+AC</em>

<em>Expand.</em>

<em>3(x+11)=3x+33</em>

<em>5x-1=3x+33</em>

<em>Add by 1 from both sides of equation.</em>

<em>5x-1+1=3x+33+1</em>

<em>Simplify.</em>

<em>5x=3x+34</em>

<em>Subtract by 3x from both sides of equation.</em>

<em>5x-3x=3x+34-3x</em>

<em>Simplify.</em>

<em>2x=34</em>

<em>Divide by 2 from both sides of equation.</em>

<em>2x/2=34/2</em>

<em>Simplify, to find the answer.</em>

<em>34/2=17</em>

<em>x=17 is the correct answer.</em>

<em>I hope this helps you, and have a wonderful day! </em>

How do I solve equations with fractions?
ratelena [41]

2y - 3/5 = 1/2

  • Add 3/5 to both sides.

2y = 1/2 + 3/5

  • Let's make the two fractions have common denominators.
  • Multiply 1/2 by 5/5 and 3/5 by 2/2.
  • 1/2 * 5/5 = 5/10
  • 3/5 * 2/2 = 6/10

2y = 5/10 + 6/10

Add the two fractions.

2y = 11/10

Divide both sides by 2.

  • 11/10 ÷ 2
  • Use the Keep, Change, Flip method.
  • Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
  • 11/10 × 1/2 = 11/20

y = 11/20

Franklin weighs 46,266,400 milligrams and his baby brother weighs 4,535.9 grams. What la there total weight in kilograms?
amm1812

Answer:

Exact: 50.8064

Rounded to nearest whole #: 51

Step-by-step explanation:

Our units are: Milligrams, Grams, and Kilograms. For Reference;

Miligrams are 1 million (1,000,000) times smaller than kilos.

Grams are 1 thousand (1,000) times smaller than kilos.

If we divide Franklins weight, 46,266,400 mg, by 1,000,000, our answer is  46.2664 kg, 46 if we round it.

Now, for his baby brother, his weight is 4,535.9 g. Divide this by 1000, and you should get 4.5359 kg, 4.5 if we round it to the nearest tenth.

Now simply add our two answers and you have both of their weight combined.

This is pretty simple, you simply can move the decimal point a certain amount of times dependent on how bigger or smaller your unit is. If we were converting kilograms to grams, we would multiply a value by 1,000, and the inverse for grams to kilograms, which moves the decimal point 3 times.

Any questions? Just ask me. Thanks.
