Answer:

12+n

Step-by-step explanation:

Hi!

8+n-4 = n+4

n+4 = n+4 (Can not be simplified).

(8+n)-4 = n+4

12+n = 12+n (Can not be simplified).

(8-4)+n = n+4

So the answer would be 12+n because it does not equal n+4.

I think the answer is n+4 because the 8 wasn’t added or subtracted.

QUESTION 1 (ONLY ANSWER FOR ALL QUESTIONS) a) 2x/3 =8 (what is x=?) b)3x/2 =6 (what is x=?) QUESTION 2 a)x/3 -2 =6 (what is x=?)
Alex777 [14]

Answer:

1 (a) x = 12

1 (b) x = 4

2 (a) x = 24

2 (b) x = 20

3 (a) x = 4

3 (b) x = 17.5

Step-by-step explanation:

1 (a)

2x/3 = 8

2x = 8 × 3

2x = 24

x = 24 ÷ 2

x = 12

1 (b)

3x/2 = 6

3x = 6 × 2

3x = 12

x = 12 ÷ 3

x = 4

2 (a)

x/3 - 2 = 6

x/3 = 6 + 2

x/3 = 8

x = 8 × 3

x = 24

2 (b)

x/5 + 1 = 5

x/5 = 5 - 1

x/5 = 4

x = 4 × 5

x = 20

3 (a)

5x/2 + 1 = 11

5x/2 = 11 - 1

5x/2 = 10

5x = 10 × 2

5x = 20

x = 20 ÷ 5

x = 4

3 (b)

2x/7 - 3 = 2

2x/7 = 2 + 3

2x/7 = 5

2x = 5 × 7

2x = 35

x = 35 ÷ 2

x = 17.5

2. Solve for x. Round to the nearest hundredth if necessary.<br> Х<br> 19<br> 29°
marysya [2.9K]

Answer:

x ≈ 34.28

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan29° = \frac{opposite}{adjacent} = \frac{19}{x} ( multiply both sides by x )

x × tan29° = 19 ( divide both sides by tan29° )

x = \frac{19}{tan29} ≈ 34.28 ( to the nearest hundredth )
