Answer:
Senior Citizen Tickets Cost = $9
Child Tickets Cost = $8
Step-by-step explanation:
Let price of senior ticket be "s", and
price of child ticket be "c"
5 senior ticket and 3 child ticket cost 69, so we can write:
Also, 1 senior and 8 child tickets cost 73, thus we can write:
Or
We can put this into 1st equation and get an equation in terms of "c" and solve for c first:
Thus, c = 8
Now,
s = 73 - 8c
s = 73 - 8(8)
s = 73 - 64
s = 9
So,
Senior Citizen Tickets Cost = $9
Child Tickets Cost = $8
Answer:
S = 14 inches
M = 18 inches
L = 23 inches
Step-by-step explanation:
Let's being by defining our variables:
Shortest piece = S
Middle piece = M
Longest piece = L
So now we need to write down what formulas we're given:
"Nagaraj has a party-length sandwich that is 55 inches long and is to be cut into three pieces"
so we can start by knowing the S + M + L = 55
"The middle piece will be 4 inches longer than the shortest piece"
This means that M - 4 = S
"the shortest piece will be 9 inches shorter than the longest piece"
Finally, this means that S + 9 = L
What we need to do now is turn all of these things into the form of one letter. We can see that S is in all three of these equations, so lets solve everything in terms of S.
M = S + 4
L = S + 9
Now we can plug in both of those things into our first equation to get:
S + S + 4 + S + 9 = 55
and now we solve :)
3S = 42
S = 14
So now given this we can use this to solve the other three lengths
M = 14 + 4 = 18
L = 14 + 9 = 23

Answer:
B
Step-by-step explanation:
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?
We can make everything have the same denominator so we can add, subtract, and compare them:
The common denominator between 2, 4, and 8, is 8.
7/8 = 7/8
1/2 = 4/8
1/4 = 2/8
The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:
Laura : 7/8
Daniel: 4/8
Annabelle: 2/8
4/8 + 2/8 = 6/8
So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:
7/8 > 6/8.
This means that Laura rowed more than Daniel and Annabelle.
