Answer:

a.x=4

b.x=4

c.(b)

Step-by-step explanation:

We are given that

9-x=5

a. First we adding x on both sides we get

9-x+x=5+x

9=5+x

Now, subtract 5 on both sides we get

9-5=x

x=4

b.

We are subtracting 9 from both sides we get

9-9-x=5-9

-x=-4

x=4

We can solve equation both approach a and b

But I prefer (b) because in approach (b)

There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .

Hence, I prefer approach (b)

Answer:

y = 2x + 54

Step-by-step explanation:

slope of equation:

(y2-y1)/(x2-x1)

= (72-58)/(9-2)

= 14/7

= 2

y = 2x + b

58 = 2(2) + b

58 = 4 + b

b = 54

How do I find X in this problem
Alona [7]

Answer: x = 16°

Step-by-step explanation:

  • This is a right triangle, which means all angles add up to 180°.
  • One of the angle is already determined to be 90°, that means the sum of the other two angles must also be 90° in order to meet a total of 180°.

This means (x+26)° + 3x° = 90°.

Solve for x:

x + 26 + 3x = 90

x + 3x = 90 - 26

4x = 64

x = 64 ÷ 4 = 16°
