case high school sold 120 tickets to the school play and took in $195 from ticket sales. if student tickets were $1 and adult tickets were $2, how many of each kind did they sell?
Answers
Explanation:
Assume that all the ticket sold were adult ticket:
120 x 2$ = 240$
Then:
240$ - 195$ = 45$
Calculate the difference between student ticket and adult ticket:
2$ - 1$ = 1$
Find the student ticket:
45$/1$ = 45
45 ticket sold is the student ticket.
Find adult ticket sold:
120 - 45 = 75
75 ticket sold is the adult ticket.
Check:
(45 x 1) + (75 x 2) = 195
45 + 150 = 195
195 = 195

The equation after simplification is [tex]7x^{6}+42x^{2} -152=0[/tex].
What is simplification of an equation?Simplification of an equation is the process of writing an equation in the most efficient and compact form without affecting the value of the original equation. It involves, multiply out the brackets and then simplify the resulting equation by collecting the like terms.
For the given situation,
The equation is
[tex]7x^{6}=2[{45-3(7x^{2} -15+6)}+4][/tex]
⇒ [tex]7x^{6}=2[{45-3(7x^{2} -9)}+4][/tex]
⇒ [tex]7x^{6}=2[{45-21x^{2} +27}+4][/tex]
⇒ [tex]7x^{6}=2[-21x^{2} +76][/tex]
⇒ [tex]7x^{6}=-42x^{2} +152[/tex]
⇒ [tex]7x^{6}+42x^{2} -152=0[/tex]
Hence we can conclude that the simplified equation is [tex]7x^{6}+42x^{2} -152=0[/tex].

Answer:
PQ=12
QR= 8
Hope it helps.
Answer: PQ = 12
QR = 8
Step-by-step explanation:
3x + 6 + 2x+4 = 20
5x = 20- 10
so, x = 2
so
PQ = 3x + 6 = 3*2+6 = 6+6 = 12

A jar contains 30 red marbles, 50 green marbles, and 20 blue marbles. What is the probability of getting a
marble that is not red when drawing one at random?
Answers
Answer:
P(not red marble)=8/11
Step-by-step explanation:
sample space is 110
subtract the red (30)
110-30=80
80/110=8/11
gg ez
Of that 100, 70 are not red (50 green + 20 blue).
This means you have a 70/100 chance of pulling something that’s not red.
70/100 reduces down to 7/10 or 70%.
