What is the measure of the smallest angle?

63°
57°
53°
64°

Answers

Answer: 53°

Step-by-step explanation:

3x - 4 + 3x + 6 + 4x - 12 = 180

10x - 10 = 180

Add 10 to both sides

10x = 190

Divide both sides by 10

x = 19

3x - 4

3 (19) - 4 = 57 - 4

= 53

3x + 6

3 (19) + 6 = 57 + 6

= 63

4x - 12

4 (19) - 12 = 76 - 12

= 64

The smallest angle is 53°

How much does a t-shirt cost?
How much does a hat cost?
pls help need it asap
20 points and a brainlist if you can explain

Answers

Answer:

£9.00

Step-by-step explanation:

67.00-49.00 = 18.00÷2 = 9.00

Let's Try:

a) 9.00×7 = 63.00+4.00(hat) = 67.00

b) 9.00×5 = 45.00+4.00(hat) = 49.00

Answer:

tshirt equals £9

and hat equals £4

Step-by-step explanation:

7t + h = 67

5t +h = 49 subtract bottom eq from top

2t = 18 t = 9

5(t) + h = 49

5(9) + h = 49

45 + h = 49

h = 4

Answers

Answer:

p = -1/5

Step-by-step explanation:

-5p + -15/5 = -4

-5p -3 = -4

-5p = -4 +3

-5p = -1

p = -1/5

Answer:

p = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Given

- 5 (p + [tex]\frac{3}{5}[/tex] ) = - 4 ← distribute parenthesis on left side by - 5

- 5p - 3 = - 4 ( add 3 to both sides )

- 5p = - 1 ( divide both sides by - 5 )

p = [tex]\frac{1}{5}[/tex]
