Step-by-step explanation:

Answer:

20.

Step-by-step explanation:

Let the number be x.

5x + 7 = 107

5x = 107 - 7

x = 100 / 5

x = 20

Answer:

After comparing we observe both equations have different answers.

Step-by-step explanation:

Find the value of [tex]\frac{5}{22}\times (\frac{3}{7}\times (-\frac{6}{11}))[/tex] and [tex](\frac{5}{22}\times \frac{3}{7})\times (-\frac{6}{7})[/tex]

Solving [tex]\frac{5}{22}\times (\frac{3}{7}\times (-\frac{6}{11}))[/tex]

[tex]=\frac{5}{22}\times (\frac{3}{7}\times -\frac{6}{11})\\=\frac{5}{22}\times (-\frac{18}{77})\\=\frac{5}{22}\times -\frac{18}{77}\\=\frac{5}{11}\times -\frac{9}{77}\\=-\frac{45}{847}[/tex]

Now solving [tex](\frac{5}{22}\times \frac{3}{7})\times (-\frac{6}{7})[/tex]

[tex]=(\frac{15}{154})\times (-\frac{6}{7})\\=\frac{15}{154}\times -\frac{6}{7}\\=\frac{15}{77}\times -\frac{3}{7}\\=-\frac{45}{539}[/tex]

After comparing we observe both equations have different answers.

8÷32

= 0.25 x 100

= 25%

Answer:

The answer is literally 3/4 as a fraction and you have to shade 15 parts.

Answer:

8:3

Step-by-step explanation:

You divide them both by 5.

Answer:

40:15 = 8:3

Step-by-step explanation:

This is the answer because:

1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:

40 ÷ 5 = 8

15 ÷ 5 = 3

8:3

Therefore, the answer is 8:3.

Answer:

4 - slope

2 - y - intercept

Step-by-step explanation:

The equation is in slope-intercept form.

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The '4' is the slope of the equation.

[tex]y=\boxed{m}x+b\\\\y=\boxed{4}x+2[/tex]

The '2' is the y-intercept.

[tex]y=mx+\boxed{b}\\\\y=4x+\boxed{2}[/tex]

Step-by-step explanation:

just think about it

Answer:

-3 or decreasing by 3

Step-by-step explanation:

To find the average change, you only care about the first and last point which would be (3,17) and (8,2)

the overall change during that time is 2-17=-15 (for the f(x) side )

the overall change during that time is 8-3=5(for the x side)

all we have to do is -15/5=-3

therefore the average rate of change is -3

Answer:

x = 10

Step-by-step explanation:

x-sqrt(2x+5) = 5

2x+5 = 25-10x+x^2

x = 10

Hope this helped!

Answer:

x = 5

Step-by-step explanation:

x - 5 = [tex]\sqrt{2x+5}[/tex] ( x > 5)

(x - 5)² = ( [tex]\sqrt{2x+5}[/tex] )²

x² - 10x + 25 = 2x + 5

x² - 12x + 20 = 0

(x - 10)(x - 2) = 0

[tex]x_{1}[/tex] = 10

[tex]x_{2}[/tex] = 2 strange root, does not satisfy the condition x > 5 ( 2 - [tex]\sqrt{2*2+5}[/tex] ≠ 5 )

10 - [tex]\sqrt{2*10+5}[/tex] = 5

10 - 5 = 5

5 = 5

Answer:

24°

Step-by-step explanation:

m∠DCE = 180° - 90° - 41° - 25° = 24° (angles on a straight line are supplementary)

This is a question on angles . If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

Answer:

C

Step-by-step explanation:

They are similar triangles as all 3 angles are same

Answer:

C. The triangles are similar

Step-by-step explanation:

Similar means same figure/shape but not the same size, congruent is exactly the same. We can see that the two triangles are similar in shape, and if u want to go that fat, they have the same angles too. But they're not the same size so they are similar.

Answer:

Earl runs 1.5 meters per second

Step-by-step explanation: 60 divided by 40= 1.5

Answer:

1.5 meters/s

Step-by-step explanation:

Since he runs 60 meters in 40 seconds, we can divide 60 by 40 to get how quickly he runs in meters/s. 60/40 = 6/4 = 3/2 = 1.5, so Earl runs 1.5 meters per second.
