OMG THANK YOU SO MUCH I NEEDED THIS SO MUCH FOR MY MATH TEST!!!!
Step-by-step explanation:
Answer:
444 adult ticket
763 student ticket
Step-by-step explanation:
let a = number of adult ticket
let s = number of student ticket
s+a=1207
5a+s=2983
get s by itself in the 1st equation so you can plug it into the 2nd
s+a=1207
-a -a
s=1207-a
5a+(1207-a)=2983
solve for a
4a+1207=2983
-1207 -1207
4a= 1776
444
this is adult ticket amount
subtract this from 1207 to get student amount
1207-444=763
Step-by-step explanation:
a triangle,=180
so 68+35-180=77
then 77+68=145
Answer:
Delia started working at 9:50 A.M.
Step-by-step explanation:
We are given that:
Delia worked for 45 minutes on her oil painting.
She took a break at 10:35 A.M.
We have to determine at what time Delia start working on the painting.
35 minutes before 10:35 A.M. is 10 A.M.
Now, 45-35=10 minutes are left
now 10 minutes before 10 A.M. is 9:50 A.M.
Hence, Delia started working at 9:50 A.M.
Answer: D
Step-by-step explanation:Lets label hot dogs as 'h' and soft drinks as 's'
6h + 4s = 13 (Equation 1)
3h + 4s = 8.50 (Equation 2)
We can solve by process of elimination.
Subtract equation 1 from equation 2.
We get:
3h = 4.5
h = 1.5
So that means that the hot dog costs $1.50 which is answer choice D.
