So essentially, we have a choice of :
2 reception halls
3 DJs
2 catering companies.
In order to find the number of arrangements, you need to multiply those : 2*3*2=12- So they have 12 arrangements.
why?
Imagine those 3 Djs- they are three arrangements.
Now, they can play in one or the other hall -so in total it's 3 Djs in one hall and 3 in the other -that's 6.
And all of those 6 possibilities can be catered by one or the other company- making the possibilities twice as many, so it's 12 in total!
For part A: the constant is 83.50. the variable would be c and w. and the coefficient would be 10c or 15w.
part B: so 10(4)+15(15)+83.50 -----> 10x4= 40------> 40+15(15)+83.50---->15x15=225
40+225+83.50=348.50
part C The coefficient would change because a constant is always constant, a variable is just a letter standing in for a number which would make the coefficient the one that changes for $10 to $20.
hope that help!
Answer:
5
Step-by-step explanation:
Let's work from the middle of the equation to the outside of it. Our first part of the equation is 3+4, which equals seven, so we have the equation:
81-2[5(7)]
Then, we multiply 5 and 7, which is 35, so we get the equation:
81-2[35]
Then we have -2 outside of the brackets, so we can multiply -2 and 35, which is -75, so we have the equation:
81-75
Which is 5.

Answer:
c. 19
Step-by-step explanation:
You must find everyone's age.
Toni is 21 and Toni's age plus Maria's age is 36. so 36-21= 15.
This tells us that Maria is 15.
Jacob's age plus Maria's age is 29. to find Jacobs age we need to subtract Maria's age from 29, 29-15 is 14.
Maria is 15,
Jacob is 14,
and Toni is 21.
Jacobs age plus marcels age is 33, so now we need to subtract Jacobs age to 33. 33-14 = 19
Marcel is 19 years old.
I hope this wasn't confusing and it helped. Have a good day.
