I'm assuming you mean #10?

So we're given this equation:

b - 5 = - 5

In this equation, we a variable of <em>b</em>. We want to solve for <em>b</em> by isolating it, or setting it alone. We see that on the side with <em>b</em> on it, it is being subtracted by 5. We want to the opposite in order to isolate <em>b</em>.

Remember that when you do one thing to one side of the equation, you must do it to the other side as well. We can add 5 on both sides to cancel out the negative 5 on the left.

b - 5 = -5&#10;&#10;add 5 on both sides&#10;&#10;b - 5 + 5 = -5 + 5&#10;&#10;simplify&#10;&#10;b = 0

Therefore we know that <em>b</em> does not equal -10, which can be represented as:

b  \neq  -10

So you have to (a) color the hair yellow.

So the answer is (a). Because -10 - 5 = -15. So it's obviously not the letter (b), since your answer in this equation is supposed to be -5. The correct equation is : 0 - 5= -5. To find this answer you must do the equation that is contrary to the subtraction which is the addition. So, -5 +5 = 0.

Hope this helps you! :)

David is making patterns using these rules. Rule for Pattern A: start with 20 and subtract 2 Rule for Pattern B: start with 10 a
pochemuha

Answer:

20,18,16,14,12,10,8,6,4,2

10,9,8,7,6,5,4,3,2,1

Step-by-step explanation:

Pattern A:

Rule : start with 20 and subtract 2

Pattern B:

Rule : Start with 10 and subtract 1

Pattern 1:

20 - 2 = 18

18 - 2 = 16

16 - 2 = 14

14 - 2 = 12

12 - 2 = 10

10 - 2 = 8

8 - 2 = 6

6 - 2 = 4

4 - 2 = 2

20,18,16,14,12,10,8,6,4,2

Pattern 2:

10 - 1 = 9

9 - 1 = 8

8 - 1 = 7

7 - 1 = 6

6 - 1 = 5

5 - 1 = 4

4 - 1 = 3

3 - 1 = 2

2 - 1 = 1

10,9,8,7,6,5,4,3,2,1

Help with length of hypotenuse ​
Salsk061 [2.6K]

Answer:

sqrt(10) *x

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

x^2 + (3x)^2 = hypotenuse ^2

x^2 + 9x^2 = hypotenuse ^2

10x^2 = hypotenuse  ^2

Take the square root of each side

sqrt( 10x^2) =  sqrt(hypotenuse  ^2)

sqrt(10) * x = hypotenuse
