Select all of the equations where x = 3 is a solution.
3x = 1
3x = 33
7x – 2 = 19
2x = 5
5x = 15
5x + 6 = 21

Answers

Answer 1

Answer:

7x-2=19

5x=15

5x+6=21

................

Answer 2

Step-by-step explanation:

Here x = 3

3x = 1 (False)

3* 3 ≠1

3x = 33 (False)

3 *3 ≠ 33

7x - 2 =19 (True)

7 *3 - 2 = 19

21 - 2 = 19

19 = 19

2x = 5 (False)

2 *3 ≠ 5

5x = 15 (True)

5 * 3 = 15

15 = 15

5x + 6 = 21 (True)

5 * 3 + 6 = 21

15 + 6 = 21

21 = 21

Hope it will help :)❤

Step-by-step explanation:

1. 100 = 100%, so seeing that there are 55 boys and 45 girls, we can go ahead and turn those into percentages, making this answer correct.

2. Once again, 100 = 100%, so 17 = 17%

3. "10/55 of those" isn't implying this is the boys only, but rather everyone, so this statement is not correct.

4. 10/35 of the students who chose math are girls. We can see that on the graph.

5. 8 + 8 = 16. Those are both the same number and half and half of the boys and girls...

In the current year Aveeno reported net income of $50,400which was a 12% increase over prior year net income Compute prior year net income

Answers

Answer:

$45000

Step-by-step explanation:

Given data

Net income =$50,400

Let the prior year income be x

12/100*x +x= 50400

0.12x+x= 50400

1.12x= 50400

x= 50400/1.12

x= $45000

Hence the prior year income is $45000

Answer:

4.25 hours

Step-by-step explanation:

A fully charged phone would be at 100%, so we'll set y equal to 100 and solve for x:

100=20x+15

85=20x

4.25=x

So Sammi's phone will be fully charged in 4.25 hours.

Answer:

4.25 hours

Step-by-step explanation:

"Fully charged" means the percentage should be 100%.

Substitute 100 for y then solve for x.

[tex]100=20x+15\\85=20x\\x=\frac{85}{20}\\x=4.25 \text{ hours}[/tex]

How do I do this I need help please?

Answers

Answer:

34.8 to 1 dp

Step-by-step explanation:

18/2 = 9

Area of rectangle 18 X 9 = 162 cm^2

diameter of each circle 9

radius = 4.5

Area of a circle = πr^2

π X 4.5^2 = 63.6172512

63.6172512 X 2 (there are 2 circles) = 127.234502

162 - 127.234502 = 34.7654975

This dot plot shows the number of runs scored by the yellow jackets in their last 12 games. How could you describe the graft?

Answers

Answer:

Symmetric

Step-by-step explanation:

The dot plot provided is almost symmetric :

Obtaining the median value :

2, 3, 5, 5, 6, 6, 6, 6, 7, 7, 7, 9

1/2 ( n + 1)

n = 12

1/2 (13) = 6.5

(6 + 6) /2

12 /2

= 6

Counting the number of points to the left and to the right of the median vlaue in the plot, we'll see that the difference in values aren't entirely different, and as such folding along the median value won't leave too much on one side than the other. Hence, the plot is symmetric.
