Let number of adult tickets be a , therefore number of student ticket be a+4 .
And total cost of the tickets is 58, that is
Distributing 2.50 on a+4
Combining like terms
Number of adult tickets are 8 and number of students tickets are 12.
First, multiply the 2 times (x-5) and you get 2x-10 on the left side.
Then on the right side, add up all the similar terms and you get 30 (the -3x and +3x cancel each other out.
2x-10=30
Then add 10 to both sides and you get 2x=40.
Then divide both sides by 2 and you get x=20.
Answer is B.
Answer:
x≥19.75
Step-by-step explanation:
Let b>a...
b=2(a+4)
b=2a+8 then we are told that:
b-a=11 using b found above in this equation gives you:
2a+8-a=11 combining like terms on left side
a+8=11 subtracting 8 from both sides
a=3
So the smaller number is 3.
...
since b=2a+8
b=14
check..
b=2(a+4)
14=2(3+4)
14=2(7)
14=14
and
b-a=11
14-3=11
11=11
Answer:
no
Step-by-step explanation:
to be a right triangle the smaller two sides squared & added together would equal the square of the longer side
does 5² + 6² = 8²?
25 + 36 = 61, not 64 so it is not a right triangle
