Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:
Now, make sure that only one of the unknown values remain on the left hand side. For example:
I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:
I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:
Then just solve the equation by finding the value of b.
Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
Answer:
7.06
Step-by-step explanation:
17/8 = 15/DF
DF = 7.06
Answer:
Ok that's not it
x=-1 then y=4
x=0 then y= 6
x=1 then y = 8
x=2 then y= 10
x=3 then y= 12
Step-by-step explanation:
when y=2x+6
you have to plug what it says x is in each of the equations.
For the first one it says x=-1
you then plug that in and you get y=2(-1)+6
then you go through PEMDAS and first you get y=-2+6
-2+6 = 4
therefore y=4
and you just go through the rest wiht that

Answer:
(g)x divided by 12/4
Step-by-step explanation:
Answer:
About 19.45%
Step-by-step explanation:
First set the fraction equal to x over 100 ———- (70/360)=(x/100)
cross multiply———- 70 * 100 = 7000 360 * x = 360x
solve for x —————- 7000=360x
7000/360= 19.44444444
Round ——- x=19.45
OR
Divide fraction ———— 70/360 = 0.1944444444
Next, convert to percentage by moving decimal 2 places to the right ——
019.44444444
Round ————- = 19.45
