Question

The table below shows the ticket rates for whale watching trips offered by Dolphin Tricks & Tours:

Age Ticket Price
Under three years free
Three to 12 years $35
Over 12 years $46

On a certain day, the company took 88 people on whale watching trips. There were 44 children aged 12 and under, of which some children were under three years. If x represents the number of children under three years, which equation can be used to find the value of x, where C represents the total amount of money collected from tickets that day?

Answer 1

(44 + x)35 + (88 - (44 + x)) • 46 = C

(88 - x)35 + (88 - 44) • 46 = C

(44 - x)35 + (88 - 44) • 46 = C

(88 + x)35 + (88 - (44 + x)) • 46 = C

Answer 6

i just need help with 2 more i dont understand

Answer 7

Solve for x.

-ax + 2b > 8

x < the quantity negative 2 times b plus 8 all over negative a

x > the quantity negative 2 times b plus 8 all over negative a

x < the quantity 2 times b minus 8 all over negative a

x > the quantity negative 2 times b minus 8 all over a

Answer 8

idk im not done yet with the test. but, hey im really goof when it comes to MATH

Answer 9

^good i meant

Answer 10

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:

C = 5 over 9(F – 32)

Which of the following formulas correctly solves for F?

F = 9 over 5C + 32

F = 9 over 5C – 32

F = 9C + 32 over 5

F = 9C - 32 over 5

Answer 11

those two im lost on and im not

Answer 12

for the second question u would have to do the following in order to isolate \[x\]

Answer 13

here this is how:
-ax + 2b > 8
-2b -2b
---------------
-ax > 8 - 2b-------> This is what you get after subtracting 2b from both sides

Answer 14

wouldnt it be 6

Answer 15

x > the quantity negative 2 times b plus 8 all over negative a

Answer 16

wait sorry meant this x > the quantity negative 2 times b minus 8 all over a

Answer 17

-ax > 8 - 2b
Then divide by -a to both sides in order to solve x

-ax/ -a would leave x but itself. Then divide -a to the right side

Answer 18

so now u would get this:
\[x> (8-2b)/-a\]

Answer 19

sorry the > would flip over <

Answer 20

\[x < (8-2b)/-a\]

Answer 21

the answer to this would be the first option actually. Because when you multiply or divide by a negative number or variable, the inequality is flipped over. In this case, we divided -a, that is why the > sign changed into the < sign.

Answer 22

thank you

Answer 23

ur welcome :)

Answer 24

same thing with 46?

Answer 25

what do you mean by 46? do you mean 4b?

Answer 26

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:

C = 5 over 9(F – 32)

Which of the following formulas correctly solves for F?

F = 9 over 5C + 32

F = 9 over 5C – 32

F = 9C + 32 over 5

F = 9C - 32 over 5

Answer 27

@phi @cwrw238

Answer 28

the answer would be like this
9/5(C) + 32 = F
