Distribute the equation 4(3x-2)=52
15x-8=52
Add 8 to both sides of the equation
12x-8=52
12x-8+8=52+8
Simply
Add the numbers
12x=60
Divide both sides of the equation by the same term
12x=60
Divide both side by 12
X=5

50 points help (show ur work)<br> Answer all of them

salantis [7]

Answer:

5. $40

6. 500 students

7. 60 books

8. 63 pages

Step-by-step explanation:

<h3><u>Question 5</u></h3>

Given:

Aiden spent $18 on souvenirs.
$18 is 45% of the money he brought on the trip.

Let x be the money Aiden brought on the trip.

Create equivalent ratios with the given information and defined variable, and <u>solve for x</u>:

$\implies 18:45\%=x:100\%$

$\implies 18:0.45=x:1$

$\implies \dfrac{18}{0.45}=\dfrac{x}{1}$

$\implies 18=0.45x$

$\implies x=\dfrac{18}{0.45}$

$\implies 40$

Therefore, Aiden brought $40 on the trip.

<h3><u>Question 6</u></h3>

Given:

Angel received 300 votes.
300 votes was 60% of all the votes.

Let x be the number of students who voted in the election.

Create equivalent ratios with the given information and defined variable, and <u>solve for x</u>:

$\implies 300:60\%=x:100\%$

$\implies 300:0.6=x:1$

$\implies \dfrac{300}{0.6}=\dfrac{x}{1}$

$\implies 300=0.6x$

$\implies x=\dfrac{300}{0.6}$

$\implies x = 500$

Therefore, there were 500 students who voted in the election.

<h3><u>Question 7</u></h3>

Given:

The students sold 80% of the books.
The total number of books they sold is 48.

Let x be the number of books in the sale.

Create equivalent ratios with the given information and defined variable, and <u>solve for x</u>:

$\implies 80\%:48=100\%:x$

$\implies 0.8:48=1:x$

$\implies \dfrac{0.8}{48}=\dfrac{1}{x}$

$\implies 0.8x=48$

$\implies x=\dfrac{48}{0.8}$

$\implies x=60$

Therefore, there were 60 books in the book sale.

<h3><u>Question 8</u></h3>

Given:

Aiyana read 147 pages of the book.
She completed 70% of the book.

If she has completed 70% of the book, then she still has 30% left to read, as 100% - 70% = 30%.

Let x be the number of pages Aiyana still has to read.

Create equivalent ratios with the given information and defined variable, and <u>solve for x</u>:

$\implies 70\%:147=30\%:x$

$\implies 0.7:147=0.3:x$

$\implies \dfrac{0.7}{147}=\dfrac{0.3}{x}$

$\implies 0.7x=44.1$

$\implies x=\dfrac{44.1}{0.7}$

$\implies x=63$

Therefore, Aiyana still has 63 pages left to read.

The sum of 2 consecutive integers is 21 what’s the two numbers

aleksklad [387]

Answer:

10 and 11

Step-by-step explanation:

Let the first integer be x.

Then the next one, since it's consecutive, must be (x+1).

The two equals 21. Thus:

$(x)+(x+1)=21$

Combine like terms:

$2x+1=21$

Subtract 1 from both sides:

$2x=20$

Divide both sides by 2:

$x=10$

So, the first integer is 10.

And the second integer is 10+1=11.

A .Dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 m/sec, while the cat can run at

Mila [183]

Answer:

33 ¹/₃ seconds

Step-by-step explanation:

Since the dog is 30 - 24 = <em>6 m/s faster than the cat</em>, that means that the dog is <em>6 meters closer to the cat each second</em>.

So, that gap will close in 200/6 = 33 ¹/₃ seconds.
