HELP PLS, 22 POINTS.Given: 2x+1/3=1 Prove: X = 1 Solve To Correctly Complete The Proof.2x+13=1 = Given2x+1=3

Answers

Answer 1

Answer:

2x+13=1, Given.

2x+1=3, multiplied both sides by 3.

2x=2, subtracted 1 from both sides.

x=1, divided both sides by 2.

NOTE: Your school may use special names for all of those proofs. If so, I don't know what they are. Sorry.

Step-by-step explanation:

For the first non-given statement, everything is over 3. A simple law of fractions is that the top number/s is being divided by the bottom, so all we need to do to reverse it is multiply it all by 3. This includes the other side.

For the second, it begins to get much easier as we've past the hardest step. Subtracting 1 from both sides gets us 2x = 2.

For the third, it is again easier. All that's left is to divide by 2 because that's what x is being multiplied by. After we do that, x turns out to be 1.

Step-by-step explanation:

I am not sure that you typed it all correctly.

but based on what is written here

f(x) = x²

g(x) = sqrt(x) + 2

so, g(f(2)) + f(1) = g(2²) + 1² = g(4) + 1 = sqrt(4) + 2 + 1 =

Talia sells educational software for a yearly salary of $65,000 plus a 2.65% commission on her total sales. If Talia sells $2.5 million of software during one year, what are Talia’s earnings for that year?

Answers

Answer:

$131250

Step-by-step explanation:

Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)

Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%

2,500,000 ÷ 100 = 25000

Step 2. Multiply this number by the specific percentage (2.65)

25000 x 2.65 = 66250

Now add the commission and the yearly salary

65000 + 66250 = 131250

Hence, total earnings of Talia were $131250

Enter the value of 3.4 (6+12).

Answers

Answer:

61.2

Step-by-step explanation:

first you add 6+12 and then multiply that number by 3.4

3.4(6+12)
solve what’s in the paranthesis
3.4 X 18
now multiply the numbers
3.4 x 18 = 61.2

Given (x – 7)2 = 36, select the values of x.

x = 13

x = 1

x = –29

x = 42

Answers

Answer:

x=1,13

Step-by-step explanation:

(x – 7)^2 = 36

Take the square root of each side

sqrt((x – 7)^2) = sqrt(36)

x-7 = ±6

x-7 = 6         x-7 =-6

Add 7 to all sides

x-7+7 = 6+7         x-7+7 = -6+7

x = 13                    x=1

Marie and Jorge are both trying to lose weight. After 3 months they compared their weight loss. Marie’s weight went from 175 to 150. Jorge’s weight went from 190 to 180. Which statements are true regarding their weight loss? Select three options.
Jorge’s weight change was approximately 5%.
Marie’s weight change was approximately 14%.
Marie had the greater percent change.
Jorge had the greater percent change.
Marie’s weight change was approximately 1.4%.

Answers

Answer:

Jorge's weight change was approximately 5%.

Marie's weight change was approximately 14%

Marie had the greater percent change.

Step-by-step explanation:

Solution:

Marie's former weight = 175

New weight = 150

Difference = 175 - 150 = 25

Percentage change = 25/175 × 100

= 1/7 × 100

= 14.2%

Jorge's former weight = 190

Jorge's new weight = 180

Difference = 190 - 180 = 10

Percentage change = 10/190 × 100

= 5.26%

From the above explanation, the following are right:

• Jorge's weight change was approximately 5%.

• Marie's weight change was approximately 14%

• Marie had the greater percent change.

Answer:

Step-by-step explanation:

Jorge’s weight change was approximately 5%.

Marie’s weight change was approximately 14%.

Marie had the greatest percent change.

Marie: 175-150 = 25

What percentage is 25 of 175 = x/100 = 25/175

= 14.29%

Jorge: 190-180= 10

What percent is 10 of 190? = x/100 = 10/190

= 5.3%

Step-by-step explanation:

(x-5)(x+4)=0;

x₁=5; x₂=-4.

Answer:

Solution 1: [tex]x = 5[/tex]

Solution 2: [tex]x = -4[/tex]

Step-by-step explanation:

The first is organize the given equation to the next form

[tex]ax^2 + bx + c[/tex]

So you substract -20 in both sides of the equation

[tex]x^2 - x - 20 = 0[/tex]

Know you can use the quadratic formula or find two number that sum give us [tex]b[/tex] and multiplied [tex]c[/tex].

[tex]b = s + r\\c = sr[/tex]

Replacing with the given values we have:

[tex]-1 = s + r\\-20 = sr[/tex]

With a trial and error the numbers are -5 and 4. Then you change the equation to

[tex]x^2 - x - 20 = (x - 5)(x + 4)[/tex]

And the equation is equal to 0 when  [tex]x[/tex] is equal to 5 and -4.

Sally picks seashells by the seashore. She lost 17 of them on her way home
With the remaining seashells, she planned to fill 5 jars with the same
number of seashells in each How many seashells did Sally originally pick?
a. You do not have enough information to solve this problem. The number
of seashells in each jar is the same as the number portion of her street
address, which is a 2-digit number. The first digit is 5. The last digit is
9 less than 3 times the first digit. How many seashells did Sally plan to
put in each jar?
b. By working backwards, determine how many seashells Sally originally
picked
C. The 5 jars that Sally chose would not each hold that many seashells In
her search for a 6th jar, she discovered a few seashells in her pocket
What are possible values for the number of seashells in each of the
6 jars and the number of seashells discovered in her pocket, such that
there are no seashells left over
(I need this ASAP! Thanks in advance!)
P.S. A step by step explanation would be really helpful ☺️

Answers

Answer:

  a) 56 shells in each jar

  b) 297 shells were picked

  c) 2, 8, 14, 20, ... shells were discovered (=2+6n); 47, 48, 49, 50, ... shells in each jar (=47+n); for n=0, 1, 2, 3, ...

Step-by-step explanation:

a)

The first digit is given as 5. The second is 9 less than 3 times 5, so is

  3×5 -9 = 15 -9 = 6

The 2-digit number that is Sally's house address is 56.

Sally originally planned to put 56 shells in each jar.

__

b)

If each of the 5 jars has 56 shells, and Sally collected 17 more than that, she originally picked ...

  5×56 +17 = 280 +17 = 297

Sally originally picked 297 shells.

__

c)

We saw that the number of shells to go into jars is 280. That will fill 6 jars with ...

  280/6 = 46 4/6 . . . . shells in each jar

That is, Sally can fill 6 jars with 46 shells each, and have 4 shells left over. The number of additional shells to put the same number in each jar will be a number that makes a multiple of 6 when 4 is added to it. Already we know that adding 2 shells will bring the total to 6 "extra", so will allow 1 more shell to be added to each of the 6 jars.

  additional shells = 2 +6n . . . . . . for some whole number n

  number in each jar = 47 +n . . . . . for the same whole number n

Sally could have discovered, 2, 8, 14, ... shells in her pocket.
