Question

I need help with a word problem and an evalutaing expression problem.

Answer 1

evaluate the expression y^2+w for y=-12 and w=-8

Answer 2

(-12)^2 + (-8)
144 - 8
136

Answer 3

Thanks...define a variable,write an equation,to solve and answer the question.the sum of three consecutive odd integers is 195.Find the integer.

Answer 4

srry idk those problems

Answer 5

(x) + (x+1) + (x+2) = 195
3x + 3 = 195
3x = 192
x = 64

Answer 6

ohh wait no odd my fault

Answer 7

(x) + (x+2) + (x+4) = 195
3x + 6 = 195
3x=189
x=63

Answer 8

sorry the first one was just for 3 consecutive integers, the bottom one is for odd integers.

Answer 9

thanks.. how about this one..
Define a variable write an equation and answer it. The tickets for a highschool musical are $6 for adults and $4 for students.A total of 310 tickets were sold.A total income of $1660 came in from ticket sales.How many adult tickets and student tickets were sold?

Answer 10

That is for a system of equations.
let a= adults, and s=students
6a + 4s = 1660 and a + s = 310

Answer 11

solve the system by substitution where a = 310 - s
6(310-s) + 4s = 1660
1860 - 6s + 4s = 1660
1860 - 2s = 1660
-2s = -200
s = 100

Answer 12

then put s back into the original equation.
a + 100 = 310
a = 210

Answer 13

Thanks a bunch!

Answer 14

you're welcome :-)
