For the first one a = 2.5. For the second one m = 4. For the third one m = -4
Addition bc. you need adding to both sides x and will get this result of 3x+2 = 11
hope helped

➷ Since vertical angles are equal, we know this:
3x + 50 = 6x - 10
Now we just need to solve for x.
Subtract 3x from both sides:
50 = 3x - 10
Add 10 to both sides:
60 = 3x
Divide both sides by 3:
x = 20

Answer:
6+y
Step-by-step explanation:
simple:)
Amount of money collected in the 2-day fundraiser is represented by the following equations:
- 12x + 4y = 152 .................. (i)
- 32x + 12y = 420 .................. (ii)
where x is the cost of a chicken lunch and y is the cost of a vegetarian lunch
Multiplying (i) with 3 and subtracting it from (ii)
36x + 12y - (32x + 12y) = 456 - 420
⇒ 4x = 36
⇒ x = 9
Put value of x in (i)
⇒ 12 × 9 + 4y = 152
⇒ 108 + 4y = 152
⇒ 4y = 44
⇒ y = 11
Hence, cost of the vegetarian meal is 11.
