Set it up in a proportion.
8 (oil)/5 (salad dressing) = x/7
cross multiply to get 11.2
1 2 4 8 and 16 are the factors
Step-by-step explanation:
3x+2y=2------------1
-3x+5y=5-----------2
adding 1 and 2 we get
7y=7
y=1
and from (1),we get
3x+2×1=2
3x=0
x=0 is the required value of x.
I need to answer two questions in order to ask a question. sorry that i’m stupid and have no idea how to do this
The first step I would do would be to list the factors of 28.
28(1)
14(2)
7(4)
Now notice that 7 + 4 = 11
So that means that -7 + -4 = -11.
Therefore, -7(-4) = 28
Your two numbers are - 7 and - 4. Hope that helps!
