You need to get 120 sooo x would need to be 25 because 25x4=100 100+20= 120. 120+60= 180°. Hope that made sense

<h2><u>Answer:</u></h2>

25° is the correct answer.

<u>Step-by-step explanation:</u>

(4x+20) +60°=180° [°.° Linear Pairs]

(4x + 20) + 60°  = 180°\\  ⟹ 4x + 20 + 60° = 180° \\  ⟹ 4x + 80° = 180° \\  ⟹ 4x =  180° - 80° \\  ⟹x =  \frac{100°}{4}  \\  ⟹25°

.°. x = 25°

sweet [91]

Answer:

19

Step-by-step explanation:

Let Sam be x

Let Susan be y


x = y+11

x + y = 27

(y+11) + y = 27

Solve the equation

2y + 11 = 27

2y = 16

y = 8


Susan's age is 8.

Sam's age is 8 + 11

Sam's age is 19


Hope this helped :)

Part A: Find a rational number that is between 7.7 and 7.9. Explain why it is rational. (2 points)
cluponka [151]
Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.

Part B.
sqrt(60) = 7.75
sqrt(60) cannot be written as a fraction of integers. It is a decimal number that never ends and never repeats.
