Answer:
The equation is p=34a+12, and a=7
Step-by-step explanation:
Perimeter is all of the sides added together
p=12a+6a+8+6a+8+10a-4
Combine like-terms
p=34a+12
Solve for a by making p equal to 250
250=34a+12
Subtract 12 from both sides
238=34a
Divide both sides by 34
7=a
The sum of a trapezoid is 360 degrees
45+90+90+x=360
45+180+x=360
225+x=360
x=135

I'm sorry if this is wrong.
Answer:
just simplify it ...
Step-by-step explanation:
- 4a-b+4b-a=180
- 3a+3b=180
- 3(a+b)=180
- both sides divide by 3
- a+b =60
- b=60-a
Answer:
N < 5
Step-by-step explanation:
"Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50" can be written as $8 = ($1.50/ticket)*N.
Dividing both sides by ($1.50/ticket) results in
$8
---------------------- = 5 1/3 tickets
($1.50/ticket)
or N < 5.
