im confused, what is it that you are asking?
Answer:
There is no graph
Step-by-step explanation:
One has to solve this using either substitution or elimination then...
x + y = 5
–2x + y = –4
x + y = 5
2x –y = 4
3x = 9
x = 3
y = 2
Solution (3 , 2)
Answer:
A
Step-by-step explanation:
Chocolate Chip 25
Oatmeal Raisin 15
Peanut Butter 22
<u>Sugar 18</u>
Total 80
A is false. If 160 students (double the original amount), approximately 36 students would buy a sugar cookie, not 18.
B is true. There are 18 students out of 80 that prefer a sugar cookie.
18/80 = 0.22 = 22%
C is true. If 240 students (triple the original amount), approximately 66 students would purchase a peanut butter cookie.
D is true. There are 40 students that prefer either chocolate chip or oatmeal raisin cookies. There are 80 students total.
25 + 15 = 40
40/80 = 1/2
Because of the parallel lines, angles A and DCE are congruent.
Also, angles E and BCA are congruent.
That makes angles B and D congruent.
m<DCE = 70 and m<EDC = 50, so m<E = 60
m<BCA = m<E = 60
Im not 100% sure what youre asking but if the value for C isnt given then it would be -7c because 3-10 is -7
(if theres a value for C can you let me know I can solve the actual thing it it would help more just lmk :)
