Answer:

There are no solutions

Step-by-step explanation:

2(x+1)=2x+5

Distribute the values on the left:

2x+2=2x+5

subtract 2x from each side

2x(-2x)+2=2x(-2x)+5

2=5

These value are not equal so there are no solutions

The answer is 3
2(x + 1) = 2x + 5
2x + 2 = 2x + 5
x = 3

Use the equation k = x÷ y to find the constant of proportionality for the set of values
Lubov Fominskaja [6]

The constant of proportionality is 1/3

and three more values are

x       1        2        3        4        5        

y       3       6        9        12       15

<h3>Variation</h3>

From the question, we are to determine the constant of proportionality

The given equation is

k = x ÷ y

From the given information,

When x = 1, y = 3

∴ k = 1 ÷ 3

k = 1/3

Thus, the constant of proportionality is 1/3

Now, we will determine the values of y for the values x = 3, x = 4, and x = 5

Since

k = x ÷ y

Then,

y = x ÷ k

When x = 3

y = 3 ÷ 1/3

y = 3 × 3

y = 9

When x = 4

y = 4 ÷ 1/3

y = 4 × 3

y = 12

When x = 5

y = 5 ÷ 1/3

y = 5 × 3

y = 15

Hence, the constant of proportionality is 1/3

and three more values are

x       1        2        3        4        5        

y       3       6        9        12        15

Solve these plz and give a explanation <br>​
77julia77 [94]

Answer:

\large{ \tt{☄ \: EXPLANATION}} :

✎ Firstly , Remember these things :

  • To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : 12\% =  \frac{12}{100}  = \boxed{  0.12}

\large{  \tt{☥ \: LET'S \: SOLVE}} :

\large{1. \:  \: 52\%  \: \text{of} \: 210 =  \frac{52}{100} \times 210 = 0.52 \times 210 =  \boxed{109.2}  }

\large{ 2. \:  \: 35\%  \: \text{of} \: 500 =  \frac{35}{100}  \times 500 = 0.35 \times 500 =  \boxed{175} }

\large{3. \: 28\%  \: \text{of}  \: 866 =  \frac{28}{100} \times 866 = 0.28 \times 366 =  \boxed{102.48} }

\large{ \tt{✺ \: REPEAT \: DAILY} }:

  • I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.

ツ Hope I helped! ۵

☃ Have a wonderful day / evening! ❃
