Enter 105
Where is the graph? not trying to be annoying just trying to answer ur question
5x - 10y = -40
-10y = -40 - 5x
y = -40 - 5x / -10
Answer:
Smoothie = 3
Ice cream = 1.5
Step-by-step explanation:
2s + i = 7.5
3s + 2i = 12
subtract the equations
(3s + 2i) - (2s + i) = s + i
s + i = 4.5
2s + i = 7.5, so s must equal 3 (7.5 - 4.5)
If s = 3, then i is 1.5 (4.5 - 3.5)
To check, plug 3 and 1.5 into s and i.
2(3) + 1.5 = 7.5
6 + 1.5 = 7.5
7.5 = 7.5
3(3) + 2(1.5) = 12
9 + 3 = 12
12 = 12
-0.5 n^2=-18
n^2= 36
n= sqrt (36)=6 or -6
Hope this can help.
