Answer:
Step-by-step explanation:
a-number of advance tickets
s-number of same day tickets
a*40+s*25=2400
a +s =75
I solve with the substitution method
s=75-a
40a+25*(75-a)=2400
40a+1875-25a=2400
15a=2400-1875
15a=525
a=525/15
a=35
so s=75-35
s=40
Answer:
Step-by-step explanation:
First lets prime factorize each number
24 = 2 x 2 x 2 x 3
36 = 2 x 2 x 3 x 3
45 = 3 x 3 x 5
GCF = 3 (3 is the only common prime number factor in the 3 numbers)
LCM = 2 x 2 x 2 x 3 x 3 x 5
= 24 x 3 x 5
= 72 x 5
= 360

Answer:
Both graphs can be used.
Step-by-step explanation:
because the time and the difficultly of the grade both depend on how long they take. Therefore it would be both graphs can be used.
Answer:
c) 31
Step-by-step explanation:
Given: f(x) = 3x + 1
We are being asked to find the function's value for x = 10.
Substitute 10 as the value of x in the function:
⇒ f(x) = 3x + 1
⇒ f(10) = 3(10) + 1
⇒ f(10) = 30 + 1
⇒ f(10) = 31
Therefore, the function's value at x = 10 is 31.

Answer:
The shape is a kite and x=26
Step-by-step explanation:
The shape is a kite because the two adjacent sides at the right match and the two sides on the left match
To find x:
125+125=250
360-250=110
(3x-11)+(2x-9)=110
Combine like terms: 5x-20=110
Add 20 to both sides: 5x-20+20=110+20
5x=130
Divide both sides by 5: 5x/5=130/5
x=26
