Answer:
2.25, 2, 4.75 I am not sure if it is correct tho
Step-by-step explanation:
the frist row shows 5 6 so basically it would be r = y + 1 (red paint being r and yellow paint being y)
1.25 + 1 + 2.25
3 - 1 = 2
3.75 + 1 = 4.75
and for part be may I know the options?
Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)

400 - 2 (24 months) = $352
Step-by-step explanation:
Answer:
AC ≈ 17.3 , BC ≈ 5.3
Step-by-step explanation:
using the tangent ratio in right triangle ACD
tan51° = 
= 
= 
( multiply both sides by 14 )
14 × tan51° = AC , then
AC ≈ 17.3 ( to the nearest tenth )
using the cosine ratio in right triangle ABC
cos72° = 
= 
= 
( multiply both sides by 17.3 )
17.3 × cos72° = BC , then
BC ≈ 5.3 ( to the nearest tenth )
