$\huge \bf༆ Answer ༄$

As we know, sum of interior angles of a triangle is 180°

that is ~

$\sf13x + 2 + 5x - 7 + 3x - 4 = 180$

$\sf21x - 9 = 180$

$\sf21x = 180 + 9$

$\sf x = \dfrac{189}{21}$

$\sf x = 9 \degree$

Hence, value of x is 9°

Answer:

x = 9

Step-by-step explanation:

Sum of interior angles is 180:

(13x + 2) + (5x - 7) + (3x - 4) = 180
21x - 9 = 180
21x = 189
x = 189/21
x = 9

A health club charges an initial fee of $100 to join, plus a fee of $33 per month. Write an algebraic equation. How much will yo

docker41 [41]

#1 answer: y=33x+100

explanation: The initial fee of $100 is your y-intercept.
The 33 is your slope.
You pay $33 a month which is what the x value represents (the month).
So your total equation is y=33x+100

#2 answer: $265

explanation: using the equation y= 33x + 100 you replace the x which is 5.
33(5) + 100. 33 * 5 = $165 but you can’t forget the + 100.
Therefore your answer will be $265.

Answer:

n = 3

Step-by-step explanation:

Equation: 17.1 = 5.7 * n

Divide both sides by 5.7 to get n by itself.

Step 1: Divide both sides by 5.7

17.1 = 5.7 * n
