Answer:
Im not sure what you are asking. But if you are using distributive property then it would be simplified to 4x-28
Sorry if this isnt what you mean .-.
The equation in required form is: -x+2y = 12
Step-by-step explanation:
Given equation is:
In order to convert the equation in 
Multiplying both sides by 2
subtracting x from both sides
Hence,
The equation in required form is: -x+2y = 12

Answer:
7/9 ÷ 1/3 = 21/9 as simplified as 7/3 in fraction form. 7/9 ÷ 1/3 = 2.3333 in decimal form.
Answer:
z = 110°
Step-by-step explanation:
Angles z and the one marked 70° form an linear pair, hence are supplementary.
z = 180° -70° = 110°
<h3>Angles where chords cross</h3>
The angle made by two chords is half the sum of the arcs intercepted by those chords. Here, that means ...
70° = 1/2(60° +x) ⇒ x = 140° -60° = 80°
The arc w completes the circle of 360°, so we have ...
w +x +79° +60° = 360° ⇒ w = 360° -219° = 141°
Finally, z is the average of w and 79°:
z = (w +79°)/2 = (141° +79°)/2 = 110° . . . as above
