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°

Maya has 3 times as many dimes as nickels. She has 4 more quarters than nickels. if she has a total of $9.40, how many of each t
puteri [66]

Answer:  nickels = 14, dimes = 42, quarters = 18

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

Let n represent nickels <em>which has a value of $0.05 </em>

Let d represent dimes <em>which has a value of $0.10</em>

Let q represent quarters <em>which has a value of $0.25</em>

It is given that:

                       n = n

                      d = 3n

                      q = n + 4

and their total value is $9.40    ⇒     n + d + q = $9.40

Use substitution to find the quantity of nickels:

.05(n) + .10(3n) + .25(n + 4) = 9.40

 5n    +  10(3n) +   25(n+4)   = 940           <em>multiplied by 100 </em>

 5n    +   30n   +  25n + 100 = 940          <em>distributed</em>

                            60n + 100 = 940          <em>added like terms</em>

                            60n           = 840          <em>subtracted 100</em>

                                 n           = 14            <em>divided by 60</em>

n = 14

                d = 3n

                   = 3(14)

                   = 42

                                       q = n + 4

                                          = (14) + 4

                                           = 18

anyanavicka [17]
The equation, y = -2x + 5, is not in standard form. The standard form of a linear line is ax + by = c. This equation is in slope - intercept form, which is y = mx + b.
