Jen Butler has been pricing​ Speed-Pass train fares for a group trip to New York. Three adults and four children must pay $ 132.
laiz [17]
Let a=price of adult ticket
let c=price of a child's ticket
start out by writing the following system of equations:
3a+4c=132
2a+3c=94
then, multiply the first equation by 2, and the second equation by 3 to get the following system of equations:
6a+8c=264
6a+9c=282
subtract the like terms to get the following equation:
-c=-18
divide both sides by -1 to get rid of the negative to get the price of a child's ticket to be $18. to find the price of an adult ticket, pick one of the original equations to substitute the 18 in for c to find a. for example:
2a+3c=94
2a+3(18)=94
2a+54=94
-54 -54
2a=40
2 2
a=20

or if you decide to use the other equation:
3a+4c=132
3a+4(18)=132
3a+72=132
-72 -72
3a=60
3 3
a=20
either way, you still get an adults ticket to be $20 and a child's ticket to be $18.

2/0 = 32/48 = 30/0. What number shpuld come in place of the zeros?​
Anton [14]

Answer:

\sf \dfrac{2}{3}  = \dfrac{32}{48}  = \dfrac{30}{45}

<h3><u>For the 1st part</u></h3>

\sf \rightarrow \dfrac{2}{x} = \dfrac{32}{48}

\sf \rightarrow 2(48)= {32x}

\sf \rightarrow 32x= 96

\sf \rightarrow x = 3

<h3><u>For the 2nd part</u></h3>

<u />\rightarrow \sf \dfrac{32}{48} = \dfrac{30}{y}

\rightarrow \sf {32y} = 30(48)

\rightarrow \sf {32y} = 1440

\rightarrow \sf y = 45

evablogger [386]
The top angle inside the triangle would be 90-20 = 70 degrees

 so X = 15 / tan(7) = 5.45 = 5.5 yd
