Answer:
Don't be lazy, do it by yourself for more brain work!
Step-by-step explanation:
5x + 4y = 24
Substitute y for 1
5x + 4 = 24
5x =20
x = 4
Answer:
that is a negative slope
but dont know how to find the slope sorry
Step-by-step explanation:
If the number of adult tickets are taken as x then the number of children’s tickets can be taken as (89 — x ) then we can set up the equation
4.10(x) + 2.70 (89 — x) = 331.30
4.10x + 240.3 — 2.70x = 331.30
1.4x = 331.30 — 240.30
1.4x = 91
X = 65
Therefore 65 adult tickets and 24 children tickets as 89 — 65 is 24
